That would be unfortunately auto generated Anonymous Type.

but is there any other way to do it? like using ToList() or IQueryble() or anything else?

You can create your own type and return IQueryable(Of ThatType).

If nothing helps don't project into a anonymous type, create a "helper-type" or just use a "general" type object/IEnumerable/IQueryable and reflect the properties in the function.

You can pass the lambda expression to the function.

public void fx(Expression<func><tinputclasstype,>> expression)
{
.........
............
}

let the function run the LINQ
