如何判断Customer和Administor

Master Page Code :

1.先判断Login是否为空，然后判断Login是否为‘Cust’或者‘Admin’，Code： if(Session['Role']==null)

{

lblbtnLogOut=false;

lblMenu.Visible=false;

}

else

{

lblbtnLogOut=true;

lblMenu.Visible=true;

ShopoingMenuSource.SiteMapProvider=Session["Role"].ToString();//Connection with Master Page

lblHi.Text="Hi "+Session["UserId"];

}
