C#遍历菜单项

（1）横向遍历  ToolStripMenuItem

foreach (ToolStripMenuItem con in this.MainMenuStrip.Items)
            {

}

（2）纵向遍历  ToolStripItem

foreach (ToolStripItem con2 in con.DropDownItems)
                {
                    if (con2 is ToolStripMenuItem)
                        if (con2.Tag == "10")
                            con2.Enabled = false;   //使此项不能选

//con2.Visible= false;     //使此项不可用

}

（3）先横后纵遍历

foreach (ToolStripMenuItem con in this.MainMenuStrip.Items)
            {
                foreach (ToolStripItem con2 in con.DropDownItems)
                {
                    if (con2 is ToolStripMenuItem)
                        if (con2.Tag == "10")
                            con2.Enabled = false;  //使此项不能选

//con2.Visible= false;     //使此项不可用

}
            }

如果能与数据库结合，就可以实现“角色”功能。例如，在系统中实现过。
