Exception Handling in C#

January 6, 2024

This post covers the basics of exception handling in C#, including try-catch blocks and handling different types of exceptions. It also discusses best practices for handling errors in your code.

Try-Catch Blocks

Exception handling in C# is primarily done using try-catch blocks. The try block contains the code that may throw an exception, and the catch block is used to handle the exception if it occurs.


try
{
    // Code that may throw an exception
}
catch (Exception ex)
{
    // Handle the exception
}

Handling Different Types of Exceptions

C# provides a variety of exception classes for different types of errors. You can use multiple catch blocks to handle different types of exceptions.


try
{
    // Code that may throw an exception
}
catch (FileNotFoundException ex)
{
    // Handle file not found exception
}
catch (DivideByZeroException ex)
{
    // Handle divide by zero exception
}

Best Practices for Exception Handling

When handling exceptions in C#, it’s important to follow best practices to ensure robust error handling in your code. Some best practices include:

  • Only catch exceptions that you can handle
  • Use specific exception types when possible
  • Log exceptions for troubleshooting
  • Handle exceptions as close to the source of the error as possible

By following these best practices, you can ensure that your code handles errors effectively and maintains its reliability.
