C＃中的讀寫操作鎖定文件

Question

第三方應用程序正在讀取我的Windows應用程序的輸出文本文件，它正在暫停。我想，這是因爲文件在寫入或讀取時被鎖定。我怎麼能讓這個工作正常。請看我的代碼。

List<string> fileList = new List<string>(); 

    System.Timers.Timer timer; 

    string currentfilename; 
    string currentcontent; 

    public Service1() 
    { 

//

 timer = new System.Timers.Timer(); 

     timer.AutoReset = false; 



     timer.Elapsed += new System.Timers.ElapsedEventHandler(DoStuff); 

    } 

    void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) 
    { 
     throw new NotImplementedException(); 
    } 

    private void DoStuff(object sender, System.Timers.ElapsedEventArgs e) 
    { 


    DateTime LastChecked = DateTime.Now; 
    try 
    { 
     string[] files = System.IO.Directory.GetFiles(@"C:\Journal", "*.jrn", System.IO.SearchOption.AllDirectories); 

     foreach (string file in files) 
     { 
      if (!fileList.Contains(file)) 
      { 
       currentfilename = file; 
       fileList.Add(file); 

        copywarehouse(file); 


       try 
       { 


         string sourcePath = @"C:\Journal"; 
         string sourceFile = System.IO.Path.Combine(sourcePath, file);

         } 


       }

        { 
         if (currentfilecontent.Contains(currentcontent)) 
         { 
          string originalcontent = currentfilecontent.Substring(currentcontent.Length);

     TimeSpan MaxWaitTime = TimeSpan.FromMilliseconds(100); 


     if (MaxWaitTime.Subtract(ts).CompareTo(TimeSpan.Zero) > -1) 
      timer.Interval = MaxWaitTime.Subtract(ts).Milliseconds; 
     else 
      timer.Interval = 1; 

     timer.Start(); 



    } 



    catch (Exception ex)

這裏的問題是與正在讀我的應用程序輸出input.it沒有允許訪問一個以上的文件內容的第三方應用程序..
