带有环境的文件夹浏览器对话框

Question

我为我父亲创建了一个应用程序。这只是一个简单的听写程序。问题是当他将它安装在他的计算机上时，它停止并说一般访问被拒绝错误。

第一次出现错误时我使用了SaveFileDialog sfd = new SaveFileDialog() 然后添加了通常的“if 语句”以确保对话框正常。但是应用程序的访问文件被拒绝。

我对@9​​87654323@ 做了同样的事情，它安装在他的电脑上并运行良好。但是，当我在工具箱外使用saveFileDialog1 和openFileDialog1 时，它不会保存或打开txt 文档。

它适用于我的笔记本电脑，而不是他的。这可能是由于代码与他的计算机中的错误。还有什么是使用Environement.GetFolder 和SaveFileDialog 的正确方法。

如果需要，我也可以将完整代码发布到程序中。

  private void lblOpenFile_Click(object sender, EventArgs e)
    {

        OpenFileDialog open = new OpenFileDialog();
        open.Title = "Open File";
        open.Filter = "Text Files (*txt) | *.txt";

        if (open.ShowDialog() == DialogResult.OK)
        {
            StreamReader read = new StreamReader(File.OpenRead(open.FileName));

            txtTextBox.Text = read.ReadToEnd();
            read.Dispose();
        }
    }

    private void lblSaveFile_Click(object sender, EventArgs e)
    {

        SaveFileDialog save = new SaveFileDialog();
        save.Title = "Save File";
        save.Filter = "Text Files (*txt) | *.txt";

        if (save.ShowDialog() == DialogResult.OK)
        {
            StreamWriter write = new StreamWriter(File.Create(save.FileName));

            write.Write(txtTextBox.Text);
            write.Dispose();
        }
    }

这是我在屏幕录像机上使用的Enviroment。我当我点击保存时，它会弹出一个对话框，我输入文件名按保存，它什么也不做。它保存文件，但不是我指定的。所以我试图合并上面和下面的代码。上面的代码没有授予访问权限，但是下面的代码没有

string OutputPath;    

OutputPath = Environment.GetFolderPath(Environment.SpecialFolder.MyVideos) + @"\\IvanSoft Desktop Recorder" + saveFileDialog1;


private void saveFileDialog1_FileOk(object sender, CancelEventArgs e)
    {
       string fileName = saveFileDialog1.FileName;
        fileName = "Tutorial";       
    }

很难说你在哪里失败了，因为尝试/捕获或记录的方式并不多。

您可以改用它，然后粘贴消息框中显示的堆栈跟踪吗？

private string fileOutputLocation { get; set; }

private void lblSaveFile_Click(object sender, EventArgs e)
{
    bool fileSelected = false;
    Try(() =>
    {
      SaveFileDialog save = new SaveFileDialog();
      save.Title = "Save File";
      save.Filter = "Text Files (*txt) | *.txt";
      save.InitialDirectory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyVideos), "IvanSoft Desktop Recorder");

      if (save.ShowDialog() == DialogResult.OK)
      {
         fileOutputLocation = save.FileName;
         fileSelected = true;
      }
   });
   if (fileSelected)
   {
      bool fileSaved = SaveFile();
      MessageBox.Show("File saved successfully: " + fileSaved.ToString());
   }
}

private bool SaveFile()
{
   TryDeleteFile();

   bool fileSaved = false;

   Try(()=>
   {
     File.WriteAllText(fileOutputLocation, txtTextBox.Text);
     fileSaved = true;
   });

   return fileSaved;
}

private void TryDeleteFile()
{
   Try(()=>
   {
      if (File.Exists(fileOutputLocation))
      {
         File.Delete(fileOutputLocation);
      }
   });
}

private void Try(Action action)
{
    try
    {
        action();
    }
    catch (Exception e)
    {
        MessageBox.Show(string.Format("The following exception was thrown:\r\n{0}\r\n\r\nFile path: {1}", e.ToString(), fileOutputLocation));
    }
}

有了这个，加上记录到 Windows 事件查看器的事件（开始>运行>Eventvwr>安全），我们应该能够告诉你问题是什么。

最后，如果你只是提供一个可执行文件来运行，你应该检查文件的属性以确保它在 Windows 中没有被阻止。
