Question: Write some code to use a delegate.Answer: Member function with a parameterusing System; namespace Console1 { class Class1 { delegate void myDelegate(int parameter1); static void Main(string[] args) { MyClass myInstance = new MyClass(); myDelegate d = new myDelegate(myInstance.AMethod); d(1); // <--- Calling function without knowing its name. Test2(d); Console.ReadLine(); } static void Test2(myDelegate d) { d(2); // <--- Calling function without knowing its name. } } class MyClass { public void AMethod(int param1) { Console.WriteLine(param1); } } } Multicast delegate calling static and member functions using System; namespace Console1 { class Class1 { delegate void myDelegate(int parameter1); static void AStaticMethod(int param1) { Console.WriteLine(param1); } static void Main(string[] args) { MyClass myInstance = new MyClass(); myDelegate d = null; d += new myDelegate(myInstance.AMethod); d += new myDelegate(AStaticMethod); d(1); //both functions will be run. Console.ReadLine(); } } class MyClass { public void AMethod(int param1) { Console.WriteLine(param1); } } } |
