無法訪問Program.cs上的處置對象主要方法

Question

我有一個WinForm應用程序有兩種不同的形式。如果第一個命令行參數是「下載」，則應出現Download表單。我在Main方法的Application.Run(new Download(args));行上獲得ObjectDisposedException行。

static class Program 
{ 
    /// <summary> 
    /// The main entry point for the application. 
    /// </summary> 
    [STAThread] 
    static void Main(string[] args) 
    { 
     Application.EnableVisualStyles(); 
     Application.SetCompatibleTextRenderingDefault(false); 
     if (args.Length > 0) 
      switch (args[0]) 
      { 
       case "download": 
        if (args.Length == 4) 
         Application.Run(new Download(args)); 
        break; 
       default: 
        Application.Run(new ApsisRunner(args)); 
        break; 
      } 
    } 
} 

更新： 異常堆棧跟蹤

Answer 1

你在下載構造函數中做這樣的事嗎？

的問題可能會在下載表格的代碼。您不應該在構造函數中關閉或處理表單。

Answer 2

您發佈的代碼是好的，但如果一個對象設置例外的任何地方occures您的下載類裏面拋出了調用堆棧直到你看到它（主要方法），

原因是你試圖設置你的窗體後可以看到它。

您可以嘗試打斷ObjectDisposed Exceptions並找到它引發的確切行，您可以在Debug - > Exceptions下執行此操作。
