这是示例代码.试试这个，

Hi,

Here is the sample code. try this,

MenuItem[] mi = new MenuItem[1];
mi[0] = new MenuItem();
mi[0].Index = 0;
mi[0].Text = "New";
mi[0].MergeType = MenuMerge.MergeItems;
          
MainMenu MM = new MainMenu();
MM.MenuItems.Add("File", mi);

我假设您已经知道如何连接到数据库，并且您已经拥有一个包含数据库表中数据的数据集.将下面的代码放在窗体的OnShown事件中

I assume you already know how to connect to the database and you already have a DataSet containing the data from the database table. Put the code below in the OnShown event of the form

DataTable dt = dataSet1.Tables[0];
MainMenu menu = new MainMenu();
List<menuitem> list = new List<menuitem>();

foreach(DataRow row in dt.Rows)
{
   MenuItem item  = new MenuItem();
   item.Text = row["menu_name"];
   list.Add(item);
}

menu.MenuItems.Add("Products", list.ToArray());
                      
this.Menu = MM;

</menuitem></menuitem>

我不太确定确切的语法，但是使用Visual Studio应该不是问题.

I''m not very sure about the exact syntax, but with visual studio that shouldn''t be a problem.
