C#速记开关语句

Question

有没有更短的方法来缩短这个开关语句？Ps:我到处都找过了，但都是复杂的。

下面是代码：

switch (type)
{
    default: case 1: Type = "MANUAL"; break;
    case 2: Type = "SELF DECOUPLING"; break;
    case 3: Type = "AUTO"; break;
    case 4: Type = "SEMI PNEUMATIC"; break;
}

Answer 1

您不能变短，但是可以使用在开关表达式 8.0中引入的C#，这样可以节省几个可打印的字符

public string SomeMethod(int type)
    => type switch
    {
       2 => "SELF DECOUPLING",
       3 => "AUTO",
       4 => "SEMI PNEUMATIC",
       _ => "MANUAL"
    };

或者如果那样的话

if (type == 2) Type = "SELF DECOUPLING";
else if (type == 3) Type = "AUTO";
else if (type == 4) Type = "SEMI PNEUMATIC";
else Type = "MANUAL";
