I want to make new ride, for it I have this code:
using (var db = new CarManagerDbEntities())
{
Guid? carId = GetCarId(carLicenceId);
if (carId == null)
{
return null;
}
Guid rideId = Guid.NewGuid();
Ride newRide = new Ride() { DriverID = driverId, CarID = carId.Value, StartDrive= startTime, Id = rideId};
db.Ride.Add(newRide);
await db.SaveChangesAsync();
return carId;
}
but in the line:
await db.SaveChangesAsync();
I get this exception:

What I'm not doing right?

I'm having some difficulty with crashing code in a Delete method (MVC). Here are two methods in my ProductItem controller class. The "Delete" works fine, but I'm getting an error message and when I step through, I notice that the DeleteConfirmed below it is getting a null value for prodID (itemID passes in fine). I have a tough time troubleshooting this because I don't know how the DeleteConfirmed method is being "called" or how the values are getting passed in (or supposed to be passed in) so I don't know what to trace or step through.
EDIT: I removed the nullable from the two arguments for itemID and productID, now it doesn't even get to DeleteConfirmed, I get this:
[ArgumentException: The parameters dictionary contains a null entry for parameter 'prodID' of non-nullable type 'System.Int32' for method 'System.Threading.Tasks.Task`1[System.Web.Mvc.ActionResult] DeleteConfirmed(Int32, Int32)' in 'Memberships.Areas.Admin.Controllers.ProductItemController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.

I figured it out, oddly enough when I had to copy the code and paste it for a new function. The problem was in the delete button itself. The model used to build the parameter string for the Edit Details and Delete buttons (code pasted below) uses "ProductID" for a parameter name, yet the controller's delete method used the argument ProdID instead of ProductID so it was coming in null!!
public string ActionParameters //Build a string containing any id paramaters which are passed in.
{
get
{
var param = new StringBuilder("?");
if(ID != null && ID>0)
{ //If the ID is not null then "id=<ID>" will be appended to the parameter string.
param.Append(String.Format("{0}={1}&","id",ID));
}
if ((ItemID ?? 0) > 0)
{ //If the ID is not null then "id=<ID>" will be appended to the parameter string.
param.Append(String.Format("{0}={1}&", "ItemID", ItemID));
}
if ((ProductID ?? 0) > 0)
{ //If the ID is not null then "id=<ID>" will be appended to the parameter string.
**param.Append(String.Format("{0}={1}&", "ProductID", ProductID));**
}
if ((SubscriptionID ?? 0) > 0)
{ //If the ID is not null then "id=<ID>" will be appended to the parameter string.
param.Append(String.Format("{0}={1}&", "Subscription", SubscriptionID));
}
return param.ToString().Substring(0,param.Length-1); //Remove last "&"
}
I found this when I had to copy and paste the code for a similar function and noticed that the arguments didn't match.
Thanks for everyone who contributed!
I am trying to use Aspnet with Roles. With the NRE, still I cannot figure out what to instantiate.
This is in the controller
[Authorize(Roles = "Admin")]
public ActionResult ForAdmin()
{
return View();
}
This is how I authorize
public Programmer GetLoginCredentials(Login credential)
{
Programmer programmer = null;
HttpContext.Current.Session["ProgrammerName"] = null;
HttpContext.Current.Session["Roles"] = null;
using (
var cmd = new SqlCommand("Sp_GetLoginCredentials", _dbConnection)
{
CommandType = CommandType.StoredProcedure
})
{
try
{
cmd.Parameters.AddWithValue("#Username", credential.Username);
cmd.Parameters.AddWithValue("#Password", credential.Password);
var da = new SqlDataAdapter(cmd);
var ds = new DataSet();
da.Fill(ds);
if (ds.Tables[0].Rows.Count <= 0) return null;
foreach (DataRow row in ds.Tables[0].Rows)
{
programmer = new Programmer()
{
ProgrammerId = Convert.ToInt32(row["ProgrammerId"]),
ProgrammerName = row["ProgrammerName"].ToString(),
Username = row["Username"].ToString(),
Password = row["Password"].ToString()
};
HttpContext.Current.Session["ProgrammerName"] = programmer.ProgrammerName;
}
if (programmer != null)
{
GetRoles(programmer);
}
return programmer;
}
catch
{
return null;
}
}
}
This is how I fill the session with roles
public List<Role> GetRoles(Programmer credential)
{
var roleList = new List<Role>();
using (var cmd = new SqlCommand("Sp_GetRoles", _dbConnection) {CommandType = CommandType.StoredProcedure})
{
cmd.Parameters.AddWithValue("#Username", credential.Username);
cmd.Parameters.AddWithValue("#Password", credential.Password);
var da = new SqlDataAdapter(cmd);
var ds = new DataSet();
da.Fill(ds);
if (ds.Tables[0].Rows.Count > 0)
{
roleList.AddRange(from DataRow row in ds.Tables[0].Rows
select new Role()
{
RoleName = row["RoleName"].ToString()
});
}
HttpContext.Current.Session["Roles"] = roleList;
}
return roleList;
}
This is my role provider
public class SiteRole : RoleProvider
{
public override string[] GetRolesForUser(string username)
{
var data = HttpContext.Current.Session["Roles"];
return data as string[];
}
}
In my Session["Roles"] I get it like this
So that means I am able to get the "Admin" role but in my browser, I get this error:

Can you please show me where I am getting it wrong? Thank you.
You cannot cast HttpContext.Current.Session["Roles"] to string[] because it's of type List<Role>
Try this instead:
public override string[] GetRolesForUser(string username)
{
var data = HttpContext.Current.Session["Roles"] as IEnumerable<Role>;
return data.Select(d => d.RoleName).ToArray();
}
I know there is lots of similar questions about this, but this is different:
This exception happens ONLY in IE.
Also this is in login page. There is #Html.AntiForgeryToken() on the form and with or without using this:
var addAntiForgeryToken = function (data, form) {
data.__RequestVerificationToken = $("#" + form + " input[type=hidden] [name='__RequestVerificationToken']").val();
return data;
};
var formdata = addAntiForgeryToken($(this), 'login-form').serialize(),
the __RequestVerificationToken field is always present in the formdata(in debug mode of IE); but always ajax login function returns this exception. Why?
The required anti-forgery form field "__RequestVerificationToken" is not present.

$("#result").html("");
if ($(this).valid()) {

wait();

else {
window.location = response.Content
}
}).fail(function (error) {

Edit 1:
The application is working locally in my computer. I am coping all the folder and sending to the server. Then, I try to access locally in the server and I get this. IIS on the server has the same configuration for Application Pool and I believe it is configured right, at least for a local use as I am doing. I am trying to get it to work locally in the server and then I´ll configure for remote use.

This is /Home/Index:

and the /Index/Login (Class has authorize attribute, only this specific method has [AllowAnonymous]) so users not yet authenticated are allowed to login

Any help?
Solved the problem adding
<modules runAllManagedModulesForAllRequests="true"/>
in the web.config
P.S. It is not the right way to do as it will load all modules at every request. Although can´t find what is not loading.
I have a WCF streaming binary files. Below is a shortened version of the contract.
[MessageContract()]
public class DocumentTransfer
{
[MessageHeader(MustUnderstand = true)]
public string Title { get; set; }
[MessageHeader(MustUnderstand = true)]
public string FileName { get; set; }
[MessageBodyMember(Order = 1)]
public System.IO.Stream Data;
}
Everything works fine but there are scenarios when only some other values associated with the file need to be updated but not the file itself. In that case the client sets Data = null. The Data property then cannot be interpreted/serialized and throws this exception:
System.ServiceModel.Dispatcher.StreamFormatter.Serialize(XmlDictionaryWriter writer, Object[] parameters, Object returnValue)
System.ServiceModel.Dispatcher.OperationFormatter.SerializeBodyContents(XmlDictionaryWriter writer, MessageVersion version, Object[] parameters, Object returnValue, Boolean isRequest)
System.ServiceModel.Dispatcher.OperationFormatter.OperationFormatterMessage.OperationFormatterBodyWriter.OnWriteBodyContents(XmlDictionaryWriter writer)
System.ServiceModel.Channels.BodyWriter.WriteBodyContents(XmlDictionaryWriter writer)
System.ServiceModel.Channels.BodyWriterMessage.OnWriteBodyContents(XmlDictionaryWriter writer)
System.ServiceModel.Channels.Message.OnWriteMessage(XmlDictionaryWriter writer)
System.ServiceModel.Channels.Message.WriteMessage(XmlDictionaryWriter writer)
System.ServiceModel.Channels.TextMessageEncoderFactory.TextMessageEncoder.WriteMessage(Message message, Stream stream)
System.ServiceModel.Channels.HttpOutput.WriteStreamedMessage(TimeSpan timeout)
System.ServiceModel.Channels.HttpOutput.Send(TimeSpan timeout)
System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.SendRequest(Message message, TimeSpan timeout)
System.ServiceModel.Channels.RequestChannel.Request(Message message, TimeSpan timeout)
System.ServiceModel.Dispatcher.RequestChannelBinder.Request(Message message, TimeSpan timeout)
System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)
System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs)
System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)
System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)
System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
...UploadDocument(DocumentTransfer request)
...UploadDocument(DocumentTransfer request) in ...
Any ideas guys?
You are getting the error in SerializeBodyContents when the body is null.
You can either create a different operation for when you do not have a file, or put a byte in the stream to avoid the exception. The first of these options is preferable, the last if you cannot change the contract.
Another option would be to return Stream.Null.
