本文實例講述了c#應用Dataset讀取XML文件靜態生成菜單的辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：

Step 1：Form1 上添加一個ToolStripContainer控件

Step2：完成代碼

private void Form2_Load(object sender, EventArgs e)
{
 CMenuEx menu = new CMenuEx();
 string sPath = "D://Menu.xml";//xml的內容
 if (menu.FileExit())
 { 
  menu.LoadAllMenu(sPath, toolStripContainer1);
  //讀取xml來加載菜單
 }
 else
 { MessageBox.Show("XML文件加載掉敗！"); }
}
/// <summary>
/// 菜單讀取類
/// </summary>
public class CMenuEx
{
 private string _Path;
 /// <summary>
 /// 設置XML設置裝備擺設文件途徑
 /// </summary>
 public string Path
 {
 get { return _Path; }
 set { _Path = value; }
 }
 /// <summary>
 /// 斷定文件能否存在
 /// </summary>
 /// <returns>文件能否存在</returns>
 public bool FileExit()
 {
 if (File.Exists(_Path))
 { return true; }
 else return false;
 }
 /// <summary>
 /// 加載菜單
 /// </summary>
 /// <param name="menuStrip">母菜單對象</param>
 public void LoadAllMenu(string sXmlPath, ToolStripContainer pToolStripContainer)
 {
 DataSet ds = new DataSet();
 ds.ReadXml(sXmlPath, XmlReadMode.Auto);
 string ToolStripPanelType = "TopToolStripPanel";
 //查找一切最後一級的菜單
 DataView dvMenuOptions = new DataView(ds.Tables["MenuOptions"], "ParentLevel=ID and ToolStripPanelType='" + ToolStripPanelType + "'", "DisplayOrder Asc", DataViewRowState.CurrentRows);
 string sParentLevel = "";
 ToolStripPanel tspTop = pToolStripContainer.TopToolStripPanel;
 tspTop.Dock = DockStyle.Top;
 ToolStrip tsTop = new ToolStrip();
 tspTop.Join(tsTop); //綁定ToolStrip
 foreach (DataRowView rvMain in dvMenuOptions)
 //輪回獲得主菜單
 {
  sParentLevel = rvMain["ParentLevel"].ToString();
  ToolStripMenuItem tsItemParent = new ToolStripMenuItem();
  tsItemParent.Text = rvMain["Text"].ToString();
  tsItemParent.Name = rvMain["Name"].ToString();
  tsTop.Items.Add(tsItemParent);//添加父菜單
  //查找父菜單下的一切子菜單
  DataView dvSub = new DataView(ds.Tables["MenuOptions"], "ParentLevel<>ID and ParentLevel='" + sParentLevel + "'", "DisplayOrder", DataViewRowState.CurrentRows);
  foreach (DataRowView rvSub in dvSub)
  {
  ToolStripMenuItem itemSub = new ToolStripMenuItem();
  itemSub.Text = rvSub["Text"].ToString() + " " + rvSub["ShortCutKeys"].ToString();
  //為菜單添加單擊事宜
  itemSub.Click += new EventHandler(toolSubItem_Click);
  //菜單呼應函數
  itemSub.Name = rvSub["Method"].ToString();
  tsItemParent.DropDownItems.Add(itemSub);
  }
 }
 }
 //自界說新聞呼應函數
 void toolSubItem_Click(object sender, EventArgs e)
 {
 //創立菜單挪用辦法類的實例
 MenuMethod menuMethod = new MenuMethod();
 Type type = menuMethod.GetType();
 //靜態獲得辦法對象
 MethodInfo mi = type.GetMethod(((ToolStripMenuItem)sender).Name);
 //挪用指定辦法
 if (mi != null)
 {
  mi.Invoke(menuMethod, null);
 }
 }
 /// <summary>
 /// 菜單的辦法列表類
 /// </summary>
 class MenuMethod
 {
 public void New()
 {
  MessageBox.Show("New");
 }
 public void Open()
 {
  MessageBox.Show("Open");
 }
 }
}
