The purpose of this article is to share with you about how to handle .net exceptions. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article.

Exception handling

You can use TryCatch activities to handle exceptions that are thrown during method execution. You can handle these exceptions or rethrow them using the Rethrow activity. Activities in the Finally section are performed when the Try section or Catches section is completed. After catching the exception, record it and ensure that the program can continue to be used normally.

Four elements of exception handling

A class type that represents the details of the exception
