类型转换 - 在 C# 中对数据类型 short 强制转换错误

关于 C# 中 int 和 short 的基本问题

为什么我会收到此代码的语法错误：

for (short i = 0; i < list.Length; i++)
{
      short key = i + (short)1; //This is where I get error
                                //Can not implicitly convert 'int' to 'short'
      //Some more code, dealing with this key...
}

某处是否有一个好的表格显示不同类型的初始值设定项快捷方式？

（就像var f = 1M;将编译成十进制）

short key = i + (short)1;

short key = (short) (i + (short)1);

short key = (short) (i + (short)1);
