【Lamda所有的Capture均是引用】
下面的程序，两个lambda 引用的实际上是同一个a、b。连int都能引用了，说明Lambda对所有类型都是以引用来处理。
1 int a = 0; 2 int b = 1; 3 Func<int> exe = ()=>{ 4 int tmp = a; 5 a = b; 6 b = tmp+b; 7 return a; 8 }; 9 Debug.Log("a1 = " + exe()); 10 Debug.Log("a2 = " + exe()); 11 Debug.Log("a3 = " + exe()); 12 Debug.Log("a4 = " + exe()); 13 Debug.Log("a5 = " + exe()); 14 15 Func<int> exe2 = ()=>{ 16 int tmp = a; 17 a = b; 18 b = tmp+b; 19 return a; 20 }; 21 Debug.Log("a1 = " + exe2()); 22 Debug.Log("a2 = " + exe2()); 23 Debug.Log("a3 = " + exe2()); 24 Debug.Log("a4 = " + exe2()); 25 Debug.Log("a5 = " + exe2());
结果为：
