How to tell if a type is a delegate

If you are holding a reference to a type, how can you tell if it’s a delegate? I expected there to be an ‘IsDelegate’ property on Type, but it isn’t there. The way I’ve found to do it, is to test if the type’s BaseType property inherits from System.MulticastDelegate.

public bool IsDelegate(Type type)
{
    return typeof (MulticastDelegate).IsAssignableFrom(type.BaseType);
}

Now this code:

Console.WriteLine("string    {0}", IsDelegate(typeof(string)));
Console.WriteLine("int       {0}", IsDelegate(typeof(int)));
Console.WriteLine("Func<int> {0}", IsDelegate(typeof(Func<int>)));
Console.WriteLine("Test      {0}", IsDelegate(typeof(Test)));

Will output this:

string    False
int       False
Func<int> True
Test      True

Do you know a better way?

Update: ‘Test’ in the example is defined like this:

public delegate int Test(int a, int b);
