Hi, i am new to C#. I am using some code similar to the one below. I am
declaring an ArrayList in one case block but the compiler complains
about it already being used in the previous case block. Is this normal
in C#? Assume that i follow this and in the first case block, i allocate
the memory using the "ArrayList mylist=new ArrayList()", and in the
second block, i just use the variable mylist like
"mylist.Add(something)". Now if the switch statement executes the second
case block first, that would case a violation, wouldn't it?

       private void button1_Click(object sender, EventArgs e)
       {
           switch (button1.Text)
           {
               case "button1":
                   ArrayList mylist = new ArrayList();
                   mylist.Add(button1.Text);
                   button1.Text = "button2";
                   break;
               case "button2":
                   ArrayList mylist = new ArrayList();
                   mylist.Add(button1.Text);
                   button1.Text = "button1";
                   break;
               default:
                   break;
           }
       }
