整数求和蓝调，短+=短问题

C#中的程序：

short a, b;

a = 10;

b = 10;

a = a + b; // Error : Cannot implicitly convert type 'int' to 'short'.

// we can also write this code by using Arithmetic Assignment Operator as given below

a += b; // But this is running successfully, why?

Console.Write(a);

Answer 1

嗯，+=接线员说你会增加a短暂的，短暂的=说你会覆写值，并具有操作的结果。手术a + b生成一个int，不知道它可以做其他操作，所以您试图将该int分配给空。
