Exception handling in C# allows programs to gracefully handle errors and unexpected problems that occur during execution. It uses keywords like try, catch, and finally to wrap code that could cause exceptions in try blocks, specify exception types to catch in catch blocks, and define cleanup code to run in finally blocks. An example of an exception is trying to divide a number by zero, which would normally cause a program to crash but can be caught and handled through exception handling.

1. EXCEPTION HANDLING

• A problem that arises during the execution of a program
• In C#, Exception Handling is a response to an exceptional
circumstance that arises while a program is running
• Eg:- an attempt to divide by zero

3. Example
Num1 = 10 Divided Num2 = 0
Answer = Infinity
Exception Occurs
IF

4. • C# exception handling is built upon four keywords
try
catch
finally
throw
• Syntax
try
{
// Statement which can cause an exception.
}
catch(Type x)
{
// Statements for handling the exception
}
finally

//Any cleanup code
}
