convert list to list

Question

How to convert List to List in C#?

Answer 1

Like this:

List longs = ints.ConvertAll(i => (long)i);

This uses C# 3.0 lambda expressions; if you're using C# 2.0 in VS 2005, you'll need to write

List longs = ints.ConvertAll(
    delegate(int i) { return (long)i; }
);
