Hi,
Is there any difference between System Exception and Exception?

Do I have to catch separately System Exception and Exception?

Thank you so much,

@A_Learner,

System.Exception and System.SystemException are both categories of exceptions but serve different purposes:

  1. System.Exception: This is the base class for all exceptions within the .NET Framework. It represents any runtime exception that might occur during program execution. When you handle exceptions of type System.Exception, you are essentially catching any exception that may be thrown in your code. However, catching more specific exception types is considered a best practice as it allows for more granular and targeted error handling.
  2. System.SystemException: This is a more specific base class for system-level exceptions within the .NET Framework, and it is derived from System.Exception. It represents exceptions thrown by the Common Language Runtime (CLR) or related to system-level issues. Examples of exceptions derived from System.SystemException include NullReferenceException, IndexOutOfRangeException, and InvalidOperationException .

Regarding whether you need to catch them separately, it depends on the specific needs of your error handling strategy. While System.Exception can catch all exceptions (since it is the more generic base class), catching System.SystemException allows you to specifically target exceptions related to system issues. For more granular handling, you might want to catch these exceptions separately.

LLM helped me to write this but it’s validated by me.
