匿名委托可以将返回值作为非void类型吗？

Question

匿名委托可以将返回值作为非void类型吗？

Answer 1

Yes. Both the delegate { return xyz; } delegate { return xyz; } and lambda x => x+1 syntax can return values.

Answer 2

I also had this question, and wrote a test program. The answer is yes.

using System;

public delegate int ReturnedDelegate(string s);

class AnonymousDelegate
{
    static void Main()
    {
        ReturnedDelegate len = delegate(string s)
        {
            return s.Length;
        };
        Console.WriteLine(len("hello world"));
    }
}
