How can I select a number and value from an enum in C#?

I have just changed my code so that now it stores some data in an enum instead of in a SQL Server table.

Here's the enum:

public enum ContentTypes : int
{
    Article = 0,
    Menu = 1,
    ContentBlock = 3
}

I was running the following code:

        var contentTypes =
          (
              from contentType in this._contentTypeService.GetContentTypes()
              select new
              {
                  id = contentType.ContentTypeId,
                  name = contentType.Name
              }
          );

How can I change this so that instead of taking the data from the content service it just queries the enum to data for contentTypes?

pswg might be right, but I am thinking you want something like this?

Here is code more direct to your question:

select new
{
    id = (int)contentType,
    name = contentType.ToString()
}

You can get the integer id simply by casting to an int and get the name of it by using its ToString (which may or may not be implicit here)

I think what you want is this

var contentTypes =
    from value in Enum.GetValues(typeof(ContentTypes)).Cast<int>()
    select new
    {
        id = value,
        name = Enum.GetName(typeof(ContentTypes), value)
    };
