How do you use exception in c sharp?

Answer 1

Exceptions are the error handling mechanism of C#. When an error occurs, an exception is thrown using this syntax:

void BadMethod()

{

bool Error = true;

if (Error)

{

throw new Exception("Whoops!");

}

}

Methods can then handle exceptions using a try/catch/finally syntax. The code that you are trying to execute goes between a try { } block, the code to handle the error goes between the catch { } block. Any code that you put between the finally { } block will always execute after the exception handling code is complete (or if an error did not occur).

void test()

{

try

{

BadMethod();

catch (Exception ex)

{

Console.WriteLine("An error occured. The description is: " + ex.Description);

}

finally

{

Console.WriteLine("I'm done!");

}

}
