The scope of a variable is the region of code from which the variable can be accessed. In general, the scope is determined by the following rules:

• A field (also known as a member variable) of a class is in scope for as long as its containing class is in scope (this is the same as for C++, Java, and VB).
• local variable is in scope until a closing brace indicates the end of the block statement or method in which it was declared.

• A local variable that is declared in a for, while, or similar statement is in scope in the body of that loop.
