string[] names = { "agen", "balen", "coure", "apple" }; string[] findNameA = Array.FindAll<string>(names, delegate(string v) { return v.StartsWith("a"); }); string[] findNameB = Array.FindAll<string>(names, v => v.StartsWith("a")); 上面中两个FindAll方法的反编译代码如下: string[] findNameA = Array.FindAll<string>(names, delegate (string v) { return v.StartsWith("a"); } ); string[] findNameB = Array.FindAll<string>(names, delegate (string v) { return v.StartsWith("a"); } ); 从而可以知道“Lambda表达式”与“匿名方法”是可以划上等号的,只不过使用“Lambda表达式”输写代码看上去更直观漂亮,不是吗?
