Structured exception handling Series

I recently saw many custom exception classes in the project and want to understand them.

Want to know why? What are the advantages of such processing? How do I frequently use custom exception classes that I need?

 

C # structured exception handling refers to dividing the names, messages, and other useful information of errors in a program into a defined package.

Build a strongly-typed custom exception so that the exception class can be used according to different problems in the program for exception handling. This makes it clearer to use, you can see what exceptions are handled here.

 

Here are the study notes. I hope you can give me more instructions:
