推荐答案

您去了:
DataTable结构:
记住您的表结构应类似于:

Hi,
Here you go:
DataTable Structure :
Remember your table structure should be like:

ID  | Description  |  ParentID  |  NavigateURL

前端编码:
要绑定菜单项，只需调用此函数:

Front-End Coding:
For binding the menu item just call this function:

//This function will bind the top menu item
private void AddTopMenuItems(DataTable menuData)
{
    DataView view = new DataView(menuData);
    view.RowFilter = "ParentID IS NULL";
    foreach (DataRowView row in view)
    {
        MenuItem newMenuItem = new MenuItem(row["Text"].ToString(), row["MenuID"].ToString());
        menuBar.Items.Add(newMenuItem);
        AddChildMenuItems(menuData, newMenuItem);
    }

}

//This code is used to recursively add child menu items by filtering by ParentID
private void AddChildMenuItems(DataTable menuData, MenuItem parentMenuItem)
{
    DataView view = new DataView(menuData);
    view.RowFilter = "ParentID=" + parentMenuItem.Value;
    foreach (DataRowView row in view)
    {
        MenuItem newMenuItem = new MenuItem(row["Text"].ToString(), row["MenuID"].ToString());
        newMenuItem.NavigateUrl = row["NavigateUrl"].ToString();
        parentMenuItem.ChildItems.Add(newMenuItem);

        AddChildMenuItems(menuData, newMenuItem);
    }
}
