How to Catch Multiple Exceptions in C#

How to Catch Multiple Exceptions in C#?

From C# 7.0 onwards, you can catch multiple exception types in a single catch block using a pipe (|) between exception types.

For example, Using catch with Multiple Exception Types (C# 7.0 and later)

try
{
    // Code that may throw exceptions
}
catch (ArgumentNullException | DivideByZeroException ex)
{
    Console.WriteLine("An exception of type ArgumentNullException or DivideByZeroException was caught: " + ex.Message);
}

In C# 6.0 and later, you can use exception filters to catch specific exceptions only if certain conditions are met, making the code more readable and expressive.

For example, Using Exception Filters (C# 6.0 and later)

try
{
    // Code that may throw exceptions
}
catch (Exception ex) when (ex is ArgumentNullException || ex is DivideByZeroException)
{
    Console.WriteLine("ArgumentNullException or DivideByZeroException caught: " + ex.Message);
}

Catching System.Exception and switching on exception types using is allows you to catch and handle specific exception types in a controlled manner.
