Is there a way to catch multiple exceptions at once and without code duplication?

Yes, there are a couple of ways to catch multiple exceptions at once in C# without code duplication:

Using a Single catch Block with Multiple Exception Types

You can catch multiple exception types in a single catch block by separating the exception types with the pipe (|) operator. Here's an example:

try
{
    // Code that may throw exceptions
}
catch (ArgumentException | NullReferenceException ex)
{
    // Handle ArgumentException and NullReferenceException
    Console.WriteLine(ex.Message);
}

In this example, if either an ArgumentException or a NullReferenceException is thrown within the try block, the catch block will handle both exceptions without duplicating the exception handling code.

Using Multiple catch Blocks with Exception Inheritance

You can also catch multiple exceptions by using multiple catch blocks, taking advantage of exception inheritance. If an exception type is not cau...
