的FolderBrowserDialog的应用程序崩溃 [英] FolderBrowserDialog crashes the application

问题描述

每当我打电话folderbrowserdialog.showDialog（）我的应用程序崩溃。
我使用的是为我工作之前代码，因此它不能代码。

Whenever I call folderbrowserdialog.showDialog() my application crashes. I'm using the code that worked before for me, so it CAN NOT be the code.

try
{
    FolderBrowserDialog fbd = new FolderBrowserDialog();
    fbd.RootFolder = Environment.SpecialFolder.Desktop;
    if (fbd.ShowDialog() == DialogResult.OK)
    {
        //  this.Minecraft.Text = fbd.SelectedPath;
    }
}
catch
{
}

它不抛出任何错误，也不例外，那里只是弹出的小负荷圈，然后应用程序走了，我之前也是不同的.net应用程序注意到了这一点！

It does not throw any error, no exception, there just pops up the little loading circle, then the app is gone, I noticed it with a different .NET app before too!

BTW：将重新安装.NET 4的工作

btw: will reinstalling .net 4 work?

推荐答案

尝试添加这对您的应用程序（在开始？在主要（）方法，最好）。查看是否exceptions.txt文件中有记录到它，当你达到冰点任何异常。

Try adding this to your application (at the start of the Main() method, preferably). See if the exceptions.txt file has any exceptions logged into it when you reach your freezing point.

        AppDomain.CurrentDomain.FirstChanceException += (sender, e) =>
        {
            if ((e == null) || (e.Exception == null))
            {
                return;
            }

            using (var sw = File.AppendText(@".\exceptions.txt")) 
            {
                sw.WriteLine(e.ExceptionObject);
            }                
        };

        AppDomain.CurrentDomain.UnhandledException += (sender, e) =>
        {
            if ((e == null) || (e.ExceptionObject == null))
            {
                return;
            }

            using (var sw = File.AppendText(@".\exceptions.txt")) 
            {
                sw.WriteLine(e.ExceptionObject);
            }                
        };
