Question

I’m sure this is easy. Infact I’m sure I’ve done this before…

I have a class of MyClass which has 2 parameters TheString and SomeInt

Somewhere, in another class I declare an List<MyClass> MyClassList and a List<String> StringList

Both have the same number of items. I want this to set all “TheStrings” in each MyClass from MyClassList equal to the corresponding String from StringList

I set MyClassList = StringList

Now I know this wont work because they’re different types. I think I’ve got to overload the assignment (=) operator but I can’t see how this is done. I suppose I could always provide a method to call from MyClass, but that isn’t quite so elegant. What would be the most elegant solution?

Thanks

You can’t overload the = operator. You could do an implicit conversion, example from MSDN:

public static implicit operator double(Digit d)
{
   return d.val;
}

However in case of lists I think the best solution is to use LINQ:

List<MyClass> list = (from value in StringList
                     select new MyClass { TheString = value }).ToList();
