(精华)2020年02月13日 WinForm进销存管理系统项目实战(MenuStrip菜单控件的使用）

1.先设置MenuStrip的Name

2.获取数据源遍历添加到菜单上

/// <summary>
///递归添加菜单项
/// </summary>
/// <param name="mList"></param>
/// <param name="pMenu"></param>
/// <param name="pId"></param>
private void AddMenuItem(List<MenuInfoModel> mList, ToolStripMenuItem pMenu, int pId)
{
    //获取所有子菜单列表
    var childList = mList.Where(m => m.ParentId == pId);
    foreach (var child in childList)
    {
        if(child.MDesp==MenuDesp.OpenSys.ToString()&&hasOpened)
        {
            continue;
        }
        if(child.MDesp==MenuDesp.UnOpenSys.ToString()&&!hasOpened)
        {
            continue;
        }
        ToolStripMenuItem mi = new ToolStripMenuItem();
        mi.Name = child.MId.ToString();
        mi.Text = child.MName;
        if (!string.IsNullOrEmpty(child.MKey))
        {
            //alt+K
            string sKey = child.MKey.ToString().Trim();
            //设置Alt快捷键  Ctrl+P   Shift+C
            if (sKey.Length > 1 && sKey.Split('+')[0].ToLower() == "alt"&& child.ParentId==0)
            {
                mi.Text += $"(&{sKey.Split('+')[1]})";
            }
            mi.ShortcutKeys = SetShortKeys(sKey);
        }
        //菜单项关联页面
        if (!string.IsNullOrEmpty(child.MUrl))
        {
            mi.Tag = child;
        }
        //菜单项响应事件注册（先没有子菜单的）有关联和没有关联页面
        if (mList.Where(m => m.ParentId == child.MId).ToList().Count == 0)
        {
            mi.Click += Mi_Click;
        }
        if (pMenu != null)
            pMenu.DropDownItems.Add(mi);
        else
            PSIMenus.Items.Add(mi);
        AddMenuItem(mList, mi, child.MId);//为当前菜单项添加它的子菜单
    }
}
