The exception is a problem that occurs during system execution. C # variance is a response to different situations while the system is running, such as dividing by zero.
The alternative provides a way to transfer control from one part of the system to another. C # external management is built on four keywords: try, hold, end, and throw.
try - A try block identifies a block of code for which particular exceptions is activated, and one or more catch blocks follow it.
catch -A program catches an exception with an exception handler at the place in a program where you want to handle the problem. The catch keyword indicates the catching of an exception.
finally - The finally block is used to create a set of statements given, whether the exception is thrown or not. For example, when you open a file, it should be closed whether a different suggestion or not.
throw- The program throws something different when a problem arises, and this is done using a keyword to throw.
Taking a block suggests a different hosting method using a combination of words to try to capture. A try/capture block is placed around the code that may produce a different one. The code inside the try/catch block is called a protected code, and the syntax for using the try/catch looks like the following -
You can write down many catch statements to catch a different type of variation if your blockchain raises more than once in various situations.
