我试图逃跑while循环。基本上，如果如果条件满足，我希望能够退出这个循环：

 私人无效CheckLog（）
{
    而（真）
    {
        Thread.sleep代码（5000）;
        如果（！System.IO.File.Exists（Command.bat））
            继续;

        使用（就是System.IO.StreamReader SR = System.IO.File.OpenText（Command.bat））
        {
            字符串s =;
            而（（S = sr.ReadLine（））！= NULL）
            {
                如果（s.Contains（MP4：生产/ CATCHUP /））
                {
                    RemoveEXELog（）;

                    进程p =新的Process（）;
                    p.StartInfo.WorkingDirectory =倾销;
                    p.StartInfo.FileName =TEST.EXE;
                    p.StartInfo.Arguments =秒;
                    p.Start（）;

                    ＆LT;＆LT;逃离这里 - 如果，如果条件满足，在这里和GT逃脱循环;＆GT;
                }
            }
        }
    }
}
 

解决方案

使用突破; 逃跑的第一个循环：

 如果（s.Contains（MP4：生产/ CATCHUP /））
{
   RemoveEXELog（）;
   进程p =新的Process（）;
   p.StartInfo.WorkingDirectory =倾销;
   p.StartInfo.FileName =TEST.EXE;
   p.StartInfo.Arguments =秒;
   p.Start（）;
   打破;
}
 

如果您也想逃避第二个循环，你可能需要使用一个标志，并检查出环路的后卫：

 布尔breakFlag = FALSE;
        而（！breakFlag）
        {
            Thread.sleep代码（5000）;
            如果继续（System.IO.File.Exists（Command.bat）！）;
            使用（就是System.IO.StreamReader SR = System.IO.File.OpenText（Command.bat））
            {
                字符串s =;
                而（（S = sr.ReadLine（））！= NULL）
                {
                    如果（s.Contains（MP4：生产/ CATCHUP /））
                    {

                        RemoveEXELog（）;

                        进程p =新的Process（）;
                        p.StartInfo.WorkingDirectory =倾销;
                        p.StartInfo.FileName =TEST.EXE;
                        p.StartInfo.Arguments =秒;
                        p.Start（）;

                        breakFlag = TRUE;
                        打破;
                    }
                }
            }
 

或者，如果你想只完全退出功能从嵌套循环，放于返回之内; ，而不是打破; 。

但这些都没有真正考虑的最佳实践。你应该找到一些方法来添加必要的布尔逻辑到你的，而卫兵。

I am trying to escape a while loop. Basically, if the "if" condition is met, I would like to be able to exit this loop:

private void CheckLog()
{
    while (true)
    {
        Thread.Sleep(5000);
        if (!System.IO.File.Exists("Command.bat"))
            continue;

        using (System.IO.StreamReader sr = System.IO.File.OpenText("Command.bat"))
        {
            string s = "";
            while ((s = sr.ReadLine()) != null)
            {
                if (s.Contains("mp4:production/CATCHUP/"))
                {
                    RemoveEXELog();

                    Process p = new Process();
                    p.StartInfo.WorkingDirectory = "dump";
                    p.StartInfo.FileName = "test.exe";
                    p.StartInfo.Arguments = s;
                    p.Start();

                    << Escape here - if the "if" condition is met, escape the loop here >>
                }
            }
        }
    }
}

Use break; to escape the first loop:

if (s.Contains("mp4:production/CATCHUP/"))
{
   RemoveEXELog();
   Process p = new Process();
   p.StartInfo.WorkingDirectory = "dump";
   p.StartInfo.FileName = "test.exe"; 
   p.StartInfo.Arguments = s; 
   p.Start();
   break;
}

If you want to also escape the second loop, you might need to use a flag and check in the out loop's guard:

        boolean breakFlag = false;
        while (!breakFlag)
        {
            Thread.Sleep(5000);
            if (!System.IO.File.Exists("Command.bat")) continue;
            using (System.IO.StreamReader sr = System.IO.File.OpenText("Command.bat"))
            {
                string s = "";
                while ((s = sr.ReadLine()) != null)
                {
                    if (s.Contains("mp4:production/CATCHUP/"))
                    {

                        RemoveEXELog();

                        Process p = new Process();
                        p.StartInfo.WorkingDirectory = "dump";
                        p.StartInfo.FileName = "test.exe"; 
                        p.StartInfo.Arguments = s; 
                        p.Start();

                        breakFlag = true;
                        break;
                    }
                }
            }

Or, if you want to just exit the function completely from within the nested loop, put in a return; instead of a break;.

But these aren't really considered best practices. You should find some way to add the necessary Boolean logic into your while guards.
