Tcp Windows服務不創建任何日誌文件

Question

我已經創建了一個Windows服務，它將打開端口並記錄文本文件中的數據。它是異步數據通信允許連接多個客戶端。但我的問題是它不會創建任何日誌文件以及它不記錄任何data.kindly指導我在哪裏我做錯了？ 這裏是我的代碼...

現在用下面的代碼，任何東西都工作正常

private static void AddtoLogFile(string Message) 
    { 
     string LogPath = @"D:\Logfile\"; 
     string filename = "Log_" + DateTime.Now.ToString("dd-MM-yyyy") + ".txt"; 
     string filepath = LogPath + filename; 
     if (File.Exists(filepath)) 
     { 
      using (StreamWriter writer = new StreamWriter(filepath, true)) 
      { 
       writer.WriteLine(Message); 
      } 
     } 
     else 
     { 
      using (StreamWriter writer = new StreamWriter(filepath, false)) 
      { 
       using(StreamWriter writer1 = File.CreateText(filepath)) 
       { 
        if(File.Exists(filepath)) 
        { 
         writer.WriteLine(Message); 
        } 
       } 
       //StreamWriter writer1 = File.CreateText(filepath); 
       //writer.WriteLine(Message); 
      } 

謝謝你們....
