Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

In languages that support implicit conversions (such as C# or VB.NET), in many cases you do not have call this constructor explicitly. When indicated, a call to an available equivalent implicit conversion operator will be created by the compiler automatically.
