C＃複選框日誌文件寫入

Question

如果複選框被選中，我試圖執行復選框來寫入日誌。

但我有這麼多的問題，所以我不知道下一步做什麼我搞砸了代碼。

如果你看圖像有複選框寫日誌，如果我檢查它並輸入IP地址，然後單擊「Ping！」按鈕，然後必須ping，同時將日誌文件寫入c：\ Logs \。

我的代碼： 「住手！」

namespace PingProgramm 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 
     } 
     Thread th; 
     private void button1_Click(object sender, EventArgs e) 
     { 
      if(checkBox1.Checked) 
      { 

      } 
      th = new Thread(thread1); 
      th.Start(); 
     } 

     public void thread1() 
     { 
      try 
      { 
       string command = "/c ping -t " + textBox1.Text; 
       ProcessStartInfo procStartInfo = new ProcessStartInfo("CMD", command); 
       Process proc = new Process(); 
       proc.StartInfo = procStartInfo; 
       procStartInfo.RedirectStandardOutput = true; 
       procStartInfo.RedirectStandardInput = true; 
       procStartInfo.RedirectStandardError = true; 
       procStartInfo.UseShellExecute = false; 
       procStartInfo.CreateNoWindow = true; 
       proc.OutputDataReceived += new DataReceivedEventHandler(proc_OutputDataReceived); 
       proc.Start(); 
       proc.BeginOutputReadLine(); 
       proc.WaitForExit(); 
      } 
      catch (Exception) 
      { 
       //if an error occurs with in the try block, it will handled here. 
      } 
     } 
     void proc_OutputDataReceived(object sender, DataReceivedEventArgs e) 
     { 
      if (stop) 
      { 
       var proc = (Process)sender; 

       stop = false; // allows you to spawn a new thread after stopping the first 
       proc.SynchronizingObject = this; // puts the form in charge of async communication 
       proc.Kill(); // terminates the thread 
       proc.WaitForExit(); // thread is killed asynchronously, so this goes here... 

      } 
      if (e.Data != null) 
      { 
       string newLine = e.Data.Trim() + Environment.NewLine; 
       MethodInvoker append =() => richTextBox1.Text += newLine; 
       richTextBox1.BeginInvoke(append); 
      } 
     } 
     bool firstTime = true; 
     private void textBox1_Click(object sender, EventArgs e) 
     { 
      if (firstTime) 
      { 
       firstTime = false; 
       textBox1.Clear(); 
      } 
     } 

     bool stop = false; 
     private void button2_Click(object sender, EventArgs e) 
     { 
      stop = true; 
     } 

     public static void WriteLog(string strLog) 
     { 
      StreamWriter log; 
      FileStream fileStream = null; 
      DirectoryInfo logDirInfo = null; 
      FileInfo logFileInfo; 

      string logFilePath = "C:\\Logs\\"; 
      logFilePath = logFilePath + "Log-" + System.DateTime.Today.ToString("MM-dd-yyyy") + "." + "txt"; 
      logFileInfo = new FileInfo(logFilePath); 
      logDirInfo = new DirectoryInfo(logFileInfo.DirectoryName); 
      if (!logDirInfo.Exists) logDirInfo.Create(); 
      if (!logFileInfo.Exists) 
      { 
       fileStream = logFileInfo.Create(); 
      } 
      else 
      { 
       fileStream = new FileStream(logFilePath, FileMode.Append); 
      } 
      log = new StreamWriter(fileStream); 
      log.WriteLine(strLog); 
      log.Close(); 
     } 

     private void checkBox1_CheckedChanged(object sender, EventArgs e) 
     { 

     } 

    } 
} 

如果我點擊按鈕，然後停止ping +停止寫入日誌。

最良好的祝願，

嘗試改變這一行：

MethodInvoker append =() => richTextBox1.Text += newLine; 

要

MethodInvoker append =() => { 
     richTextBox1.Text += newLine; 
     if (checkBox1.Checked) 
     { 
      WriteLog(newLine); 
     } 
    };
