Custom Exception Handling in C#

Rule of thumb is to avoid throwing System.Exception or System.ApplicationException. I created a custom exception (below) which inherits from Exception.

Implement standard exception constructors

Types should not extend certain base types

[Serializable]
public class MyCustomException : System.Exception
{
public MyCustomException(){}

public MyCustomException (string message) : base (message) {}

public MyCustomException (string message, Exception innerException) :
base(message, innerException){}

protected ProcessorException(SerializationInfo info, StreamingContext context) :
base (info, context) {}

}
