How to Fix: How to catch SQLServer timeout exceptions

Catching SQLServer timeout exceptions in C# using try-catch blocks and exception handling.

Quick Answer: Use the SqlException class and check for the 'Timeout' error code, which is 1205.

To catch SQLServer timeout exceptions, it is recommended to use a custom exception handler that can identify and handle the specific error code associated with timeout exceptions. The SqlException class in .NET provides a unique error code for timeout exceptions, which can be checked using the ErrorCode property.
