c# - 检查对象是否有带有委托(delegate)签名的方法

Question

如何检查对象是否具有与特定委托(delegate)具有相同签名的方法

    public delegate T GetSomething<T>(int aParameter);
    public static void Method<T>(object o, GetSomething<T> gs)
    {
        //check if 'o' has a method with the signature of 'gs'
    }

Answer 1

// You may want to tweak the GetMethods for private, static, etc...
foreach (var method in o.GetType().GetMethods(BindingFlags.Public))
{
    var del = Delegate.CreateDelegate(gs.GetType(), method, false);
    if (del != null)
    {
        Console.WriteLine("o has a method that matches the delegate type");
    }
}
