C#中下拉窗口权限动态设置

private void button1_Click(object sender, EventArgs e)




...{


//权限字符串


String ls_a, ls_b, ls_c, ls_d;


ls_a = "1111";


ls_b = "1001";


ls_c = "0011";


ls_d = "1100";


int li_count;


li_count = a.DropDown.Items.Count;


//循环为每个纵向的窗口赋权限


for (int i=0; i < li_count; i++)




...{


string ls_str2, ls_str1,ls_str3,ls_str4;


ls_str1 = ls_a.Substring(i, 1);


if (ls_str1 == "1")




...{


a.DropDown.Items[i].Visible = true;


}


ls_str2 = ls_b.Substring(i, 1);


if (ls_str2 == "1")




...{


b.DropDown.Items[i].Visible = true;


}


ls_str3 = ls_c.Substring(i, 1);


if (ls_str3 == "1")




...{


cToolStripMenuItem.DropDown.Items[i].Visible = true;


}


ls_str4 = ls_d.Substring(i, 1);


if (ls_str4 == "1")




...{


dToolStripMenuItem.DropDown.Items[i].Visible = true;


}
