C# WinForm 读写XML文件

 

建立一个WinForm应用程序 添加MenuStrip控件，填写两个功能“读取” 和“导出数据”。

        用了两个DataSet控件和对话框“打开(OpenFilesDialog控件)"和"保存(SaveFilesDialog控件)"

        读取

private void 读取ToolStripMenuItem_Click(object sender, EventArgs e)                 {                      if (opFileDlg .ShowDialog() == DialogResult.OK)                     {                          if(opFileDlg .OpenFile()!=null)                          {                              twoXML .ReadXml (@opFileDlg .FileName );
