Explanation
The output is as follows: The output is as follows: Connecting to server SMTP Error: Server busy Connection closed In the try block, the first Console.WriteLine command runs. The Throw command stops execution and processing resumes in a catch block. Because the first catch block matches the exception type thrown, processing resumes in the first catch block. After the catch block has finished running, processing continues inside the finally block. The try...catch block is used to handle runtime errors. In an event procedure, the try statement is placed just before the statements that might cause an error. The catch statement is placed just before the list of statements that are to be run if a runtime error occurs. For example: //Statements that might cause a runtime error. //Statements to be run if a runtime error occurs. A block of code that appears just after the finally statement is called a finally block. The statements in a finally block are executed immediately after execution of the try/catch block. The finally block is optional. However, each try statement must have at least one catch block or a finally block. When a finally block is defined in a source code, it is guaranteed to execute, regardless of whether or not an exception is thrown.
