c# try catch finally

The try-catch-finally block is a fundamental concept in C# programming for handling exceptions.

The try block contains the code that may throw an exception. If an exception is thrown, the catch block is executed, which catches the exception and handles it accordingly. The finally block is always executed, regardless of whether or not an exception is thrown.

Syntax:

try {
  // code that may throw an exception
}
catch (ExceptionType1 e1) {
  // handle exception e1
}
catch (ExceptionType2 e2) {
  // handle exception e2
}
finally {
  // code that will always be executed
}

In the above syntax, the catch block can handle multiple exceptions of different types. If no exception is thrown, the catch block is skipped and only the finally block is executed.

The finally block is used to clean up resources that were used in the try block, such as closing a file or releasing memory. It is also used to ensure that certain code is executed, regardless of whether or not an exception was thrown
