帶環境的文件夾瀏覽器對話框

Question

我爲我父親創建了一個應用程序。這只是一個簡單的聽寫程序。事情是，當他安裝在他的電腦上，它停滯不前，並說一般訪問被拒絕錯誤。

的第一次給了我以前SaveFileDialog sfd = new SaveFileDialog()錯誤，然後加入通常是「if語句」，以確保對話是好的，但應用程序有一個訪問文件被拒絕。

我做同樣的事情Environment.GetFolder而且它安裝在他的電腦上的位置並且運行良好，但是當我使用工具箱中的saveFileDialog1和openFileDialog1時，它並不保存或打開一個txt文檔。這可能是由於代碼與他的電腦有錯誤。還有什麼是正確的方式使用Environement.GetFolder與SaveFileDialog。

如果需要，我也可以將完整的代碼發佈到程序中。

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(); 
     } 
    } 

這是我在屏幕錄像機上使用的Enviroment。我當我點擊保存它會調出一個對話框，我把文件名按保存，它什麼都不做。它保存文件，但不是我指定的。所以我試圖合併上面和下面的代碼。上面的代碼不授予訪問權限但下面確實

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";  
    }

很難說得清你失敗，因爲沒有在路上多嘗試/捕捉或記錄。

您可以使用它來粘貼顯示在消息框中的堆棧跟蹤嗎？

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)); 
    } 
} 

有了這個，再加上記錄到Windows事件查看器（開始>運行> EVENTVWR>安全）事件，我們應該能夠告訴你問題是什麼。

最後，如果您只是提供可運行的可執行文件，則應該檢查該文件的屬性以確保它不會在Windows中被阻止。
