在winfrom窗體中放一個文本框，2個按鈕，一個panle，以下圖

form.cs文件中的代碼：

  //讀取xml內容
  private void button1_Click(object sender, EventArgs e)

   fileName.InitialDirectory = Application.StartupPath;//設置翻開控件後，默許目次為exe運轉文件地點文件夾
   fileName.Filter = "一切XML文件|*.XML";//設置控件翻開的文件類型
   fileName.FilterIndex = 2;//設置控件翻開文件類型的顯示次序
   fileName.RestoreDirectory = true;//設置對話框能否記憶之前翻開的目次
   if (fileName.ShowDialog() == DialogResult.OK)
   {
     Path = fileName.FileName.ToString();//取得用戶選擇的完全途徑
     Name = Path.Substring(Path.LastIndexOf("\\") + 1);//獲得用戶選擇的不領路徑的文件名

  //修正xml中一切的內容
  public void SavaConfig()

      break;
     }


    }


   }
   XMLDoc.Save(path);//保留。 
  }
  //修正xml中某一個節點
  public void SavaXMLConfig(int tag, string Name)

   strlist[tag] = Name;
  }
