The Equality method defines the operation of the equality operator for the String class.

This operator is implemented using the Equals method, which means the comparands are tested for a combination of reference and value equality. This operator performs an ordinal comparison.

NoteNote:

   The Visual Basic compiler does not resolve the equality operator as a call to the Equality method. Instead, the equality operator wraps a call to Operators.CompareString.

The following example demonstrates the equality operator.
