Question

if(){
      String var=1; 
      if(var==-1){
        //do this
      }
      else
      {
         if()
         {        
           String myString=var; //This is where I want to use var
         }
      }
}

Now myString is not getting assigned the value of var..why is that ? It’s nested if..it should get the value..isn’t it ?

Following code seems to work fine:

if (true)
{
    String var = "1";
    if (var == "-1") {/*DoSomething()*/ }
    else
    {
        if (true)
        {
            String myString = var; //Gives 1 in myString!
            MessageBox.Show(myString);
        }
    }
}

Variable and Method Scope in Microsoft .NET is a good reference to understand how scoping
works.

Btw, var is a type used in 3.5 and above; should avoid naming variables akin to type names.
