int to string in Entity Framework

Question

How do you convert an int to a string in Link to EF?

The clr cant imagine casting an int to a string and Entity framework cant figure out what SQL snippet to translate .ToString() into.

So how do you write a linq statement that returns a string instead of an int?

Sadly EF does not know how to convert .ToString(). You must use the embedded function SqlFunctions.StringConvert: http://msdn.microsoft.com/en-us/library/dd466292.aspx Also there is no overload for int so you must typecast to double :-(

var vendors = 
   from v in Vendors  
   select new
   {             
       Code = SqlFunctions.StringConvert((double)v.VendorId)
   };
