IQueryable<a> to list<b> type conversion, when a & b having similar signature using LINQ

asp.net-mvc-3, c#, entity-framework, linq-to-entities, linq-to-sql

Solution

You need to use `Select` to project from one type to another, then `ToList` to create a list:

// Property names changed to follow .NET naming conventions
var list = query.Select(a => new B { X = a.A, Y = b.B, Z = c.C })
                .ToList();

The compiler and runtime wouldn't care if your types had the same properties (not that they do in this case - they have different names) - they're still entirely separate types.

Problem

I'm having some basic problem with linq, I tried to google but didn't get the desired reuslt. Lets say We have two class with almost similar signature like these: ``` public class A { public int a { get; set; } public int b { get; set; } public int c { get; set; } } public class B { public int x { get; set; } public int y { get; set; } public int z { get; set; } } ``` Here A is data context class which is generated by the framework while creating the .edmx file & B is my custom class to carry data to UI. I'm querying the data base using A & getting a iqueryable list. Now I need to convert this list into another list of type B. How can I do that?
