How do I convert an HttpRequest into an HttpRequestBase object? - asp.net-mvc

Question

My problem is the opposite of this:
How do I convert an HttpRequestBase into an HttpRequest object?
In my ASP.NET MVC application I have a method used by many controllers that receive an HttpRequestBase as argument.
Now I have to call that method from another method, that is not an action (it's an nhibernate interceptor). In this second method I could access HttpContext.Current.Request, that is a HttpRequest and I cannot cast it to HttpRequestBase (I thought it was possibile due to the naming ...).
Does someone know in what relationship are this classes and how can I solve my problem?
Thank you.

Answer 1

You'll want to wrap your HttpRequest in a HttpRequestWrapper:
var wrapper = new HttpRequestWrapper(httpRequest);
The HttpRequestWrapper inherits from HttpRequestBase.

Answer 2

This is an another solution which does not require to create a new instance:
var httpRequestBase = myHttpRequest.RequestContext.HttpContext.Request;

Answer 3

In my application I had calls coming from several different places that needed access to the HttpRequestBase. I created this set of extension methods to get and convert from several different Http types into a HttpRequestBase, then used HttpRequestBase as the base type for interface and class methods through the application when I needed access to the request.
public static class RequestExtensions
{
public static HttpRequestBase GetHttpRequestBase(this HttpContext httpContext)
{
if (httpContext == null)
{
throw new ArgumentException("Context is null.");
}
return httpContext.Request.ToHttpRequestBase();
}
public static HttpRequestBase GetHttpRequestBase(this HttpRequestMessage httpRequestMessage)
{
if (httpRequestMessage == null)
{
throw new ArgumentException("Request message is null.");
}
HttpContextWrapper context = null;
if (httpRequestMessage.Properties.ContainsKey("MS_HttpContext"))
{
context = httpRequestMessage.Properties["MS_HttpContext"] as HttpContextWrapper;
}
if (context == null)
{
throw new ArgumentException("Context is null.");
}
return context.Request;
}
public static HttpRequestBase GetHttpRequestBase(this HttpApplication httpApplication)
{
if (httpApplication == null)
{
throw new ArgumentException("Application is null.");
}
return httpApplication.Request.ToHttpRequestBase();
}
public static HttpRequestBase ToHttpRequestBase(this HttpRequest httpRequest)
{
if (httpRequest == null)
{
throw new ArgumentException("Request is null.");
}
return new HttpRequestWrapper(httpRequest);
}
}
I came across several SO answers that helped me build these extensions:

Convert HttpRequestMessage to HttpRequest
Get the IP address of the remote host

I find the following extension methods useful:
public static HttpContextBase AsBase(this HttpContext context)
{
return new HttpContextWrapper(context);
}
public static HttpRequestBase AsBase(this HttpRequest context)
{
return new HttpRequestWrapper(context);
}
Usage:
HttpContext.Current.AsBase()
HttpContext.Current.Request.AsBase()
