public delegate void TheEvent(int a); public void test() { TheEvent testdel1 = new TheEvent(del1); testdel1(12); } public void del1(int x) { Console.WriteLine("output x : {0}", x); } |
现在我们可以写成这样:
public void test() { TheEvent testdel1 = del1; testdel1(12); } |
或者将程序改写为:
delegate void TheEvent2(int a); public void test2() { int a = 12; TheEvent ev2 = delegate(ref int x) { Console.WriteLine("output x : {0}", x); }; ev2( ref a); } |
如下代码将是委托本质的提高?让我们看看下面的例子。
public static void test3() { int a = 12; int y = 32; TheEvent ev2 = delegate(ref int x) { Console.WriteLine("output x + y : {0}", x + y); }; ev2( ref a); } |
