There are the following 2 types of exceptions:
There are the following 2 types of exceptions:
- System Exception.
- Application Exception.
System Exception
An exception raised implicitly from some predefined condition is a “System Exception”. For example DivideByZeroException, FormatException, OverFlowException and NullReference Exception.
If you want to learn about system exceptions then read my article:
Finally Block
Application Exception
An exception that is raised explicitly by the programmer in the application on its own condition is an “Application Exception”.
It can also referred to as a “User Defined Exception”.
Now let's we learn how to develop our own User Defined Exception.
Use the following procedure to develop a User Defined Exception.
Step 1: Inherit a class from the Exception class.
For example : Exception
Step 2: Override the string message from the exception class.
For example:
An exception raised implicitly from some predefined condition is a “System Exception”. For example DivideByZeroException, FormatException, OverFlowException and NullReference Exception.

For example:
Public override string Message
{
get
{
Return “Display the error Message when Exception Occur”
}
}
Step 3: In the other class, if an exception occurs that throws an exception for the creation of an object of your own exception class then do something.
For example:
Throws new
