使用枚举+切换 [英] Using Enum + Switch

问题描述

我想知道为什么我的Switch语句在这样的情况下不起作用:

I want to know why my Switch statement is not working if I have something like this:

public enum cond
{ checknum,
  checkval
}
private string data()
{ cond condtype = cond.checknum;
  switch (condtype)
  { case cond.checknum:
    // ... code
    break;
  }
}

似乎永远都不要输入任何条件类型...

有什么主意吗?

It looks like never enter in any condtype...

any idea ?

推荐答案

您忘记了冒号

You forgot the colon

private string data()
{ cond condtype = cond.checknum;
  switch (condtype)
  { case cond.checknum:
    // ... code
    break;
  }
}

但是，这根本没有任何意义.为什么需要开关来确定已设置的内容?

However, this makes no sense at all. Why do you need a switch to determine what you have already set?

这对我来说似乎很正常

This is what I did seems to be working fine for me

class Program
{
    public enum cond
    {
        checknum,
        checkval
    }
    static private void data()
    {
        cond condtype = cond.checknum;
        switch (condtype)
        {
            case cond.checknum:
                Console.WriteLine("I am checknum");
                break;
            case cond.checkval:
                Console.WriteLine("I am checkval");
                break;
            default:
                Console.WriteLine("I am no one");
                break;
        }
    }
    static void Main(string[] args)
    {
        data();
        Console.ReadKey();
    }
}

我建议您在代码的其他方面查看该问题.

I suggest you look at other areas of the code for the problem.
