Create new content nodes programmatically in Umbraco 8 - umbraco

Question

In Umbraco 7 I used the following code to generate code programmatically from C# (controller)
using ContentService.CreateContent
And following is the code for the same
int parentID = 1100;
var request = ContentService.CreateContent("New Node Name", parentID, ContactUsForm.ModelTypeAlias);
request.SetValue(ContactRequestItem.GetModelPropertyType(C => C.FirstName).PropertyTypeAlias, FormModel.FirstName);
ContentService.PublishWithStatus(request);
Now in Umbraco 8
it is asking for
Udi ParentId
getting error "Can not convert 'int' to 'Umbraco.Core.Uid' ".
Have searched a lot, but can't find anything for Umbraco 8.
So now the question is How we can create a node from a controller in Umbraco 8?

Answer 1

How about getting the parent node first (this can be done via int ID) and then get the UDI from that? Something like
var parent = ContentService.GetById(1100);
var request = ContentService.CreateContent("New Node Name", parent.GetUdi(), ContactUsForm.ModelTypeAlias);

Answer 2

The solution is as suggested on the following the link
on the Umbraco Forum
public IContentService _contentService { get; set; }
public TestController(IContentService contentService)
{
_contentService = contentService;
}
public override ActionResult Index(ContentModel model)
{
var parentId = new Guid("3cce2545-e3ac-44ec-bf55-a52cc5965db3");
var request = _contentService.Create("test", parentId, ContentPage.ModelTypeAlias);
_contentService.SaveAndPublish(request);
return View();
}

Answer 3

In Umbraco 8, you need the parent Udi to create a new node. You can do this by getting the parent node first then getting the Udi using the parent node like this:
var parentNode = ContentService.GetById(1100);
var parentUdi = new GuidUdi(parentNode.ContentType.ToString(), parentNode.Key);
You can then call the CreateContent method and pass in the parentUdi as a parameter:
var request = ContentService.CreateContent("New Node Name", parentUdi, ContactUsForm.ModelTypeAlias);
ContentService.SaveAndPublish(request);
