我有一个WinForm有两种不同形式的应用程序。如果第一个命令行参数是"download"，则Download应该出现该表单。我得到了ObjectDisposedException关于我的程序方法的Application.Run(new Download(args));在线信息。Main

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;
            }
    }
}

您是否在“下载的构造函数”表单中做类似的事情？

问题可能出在下载表单的代码中。您不应在构造函数中关闭或处置 Form。

您发布的代码很好，但是如果在您的 Download 类中的任何地方发生对象处理异常，它将被抛出调用堆栈，直到您看到它（主要方法），

原因是您尝试在处置表单后将其设置为可见。

您可以尝试中断 ObjectDisposed Exceptions 并找到它被抛出的确切行，您可以在 Debug -> Exceptions 下这样做。
