示例

下面的示例将的内容RichTextBox保存到 ASCII 文本文件中。The following example saves the contents of the RichTextBox into an ASCII text file. 该示例使用SaveFileDialog类来显示一个对话框, 用于请求用户的路径和文件名。The example uses the SaveFileDialog class to display a dialog to request the path and file name from the user. 然后, 代码将控件的内容保存到该文件。The code then saves the contents of the control to that file. 该示例使用SaveFile方法的此版本来指定将文件另存为 ASCII 文本文件, 而不是标准格式文本格式。The example uses this version of the SaveFile method to specify that the file be saved as an ASCII text file instead of the standard Rich Text Format. 此示例假设代码放置在一个Form RichTextBox具有名为richTextBox1的控件的类中。This example assumes that the code is placed in a Form class that has a RichTextBox control named richTextBox1.

public:
   void SaveMyFile()
   {
      // Create a SaveFileDialog to request a path and file name to save to.
      SaveFileDialog^ saveFile1 = gcnew SaveFileDialog;
      
      // Initialize the SaveFileDialog to specify the RTF extension for the file.
      saveFile1->DefaultExt = "*.rtf";
      saveFile1->Filter = "RTF Files|*.rtf";
      
      // Determine if the user selected a file name from the saveFileDialog.
      if ( saveFile1->ShowDialog() == System::Windows::Forms::DialogResult::OK &&
         saveFile1->FileName->Length > 0 )
      {
         // Save the contents of the RichTextBox into the file.
         richTextBox1->SaveFile( saveFile1->FileName, RichTextBoxStreamType::PlainText );
      }
   }
public void SaveMyFile()
{
   // Create a SaveFileDialog to request a path and file name to save to.
   SaveFileDialog saveFile1 = new SaveFileDialog();

   // Initialize the SaveFileDialog to specify the RTF extension for the file.
   saveFile1.DefaultExt = "*.rtf";
   saveFile1.Filter = "RTF Files|*.rtf";

   // Determine if the user selected a file name from the saveFileDialog.
   if(saveFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK &&
      saveFile1.FileName.Length > 0) 
   {
      // Save the contents of the RichTextBox into the file.
      richTextBox1.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText);
   }
}

Public Sub SaveMyFile()
    ' Create a SaveFileDialog to request a path and file name to save to.
    Dim saveFile1 As New SaveFileDialog()
    
    ' Initialize the SaveFileDialog to specify the RTF extension for the file.
    saveFile1.DefaultExt = "*.rtf"
    saveFile1.Filter = "RTF Files|*.rtf"
    
    ' Determine if the user selected a file name from the saveFileDialog.
    If (saveFile1.ShowDialog() = System.Windows.Forms.DialogResult.OK) _
        And (saveFile1.FileName.Length) > 0 Then
    
        ' Save the contents of the RichTextBox into the file.
        richTextBox1.SaveFile(saveFile1.FileName, _
            RichTextBoxStreamType.PlainText)
    End If
End Sub
