CSharp - Introduction Local variables

Introduction

The scope of a local variable/constant is its own block and nested block.

You cannot declare another local variable with the same name in the block or in any nested blocks. For example:

static void Main()
{
       int x;
       {
         int y;
         int x;            // Error - x already defined
       }
       {
         int y;            // OK - y not in scope
       }
       Console.Write (y);  // Error - y is out of scope
}
