What is error C#?

When executing C# code, different errors can occur: coding errors made by the programmer, errors due to wrong input, or other unforeseeable things.

How do you handle errors in C#?

C# exception handling is built upon four keywords: try, catch, finally, and throw.

  1. try − A try block identifies a block of code for which particular exceptions is activated.
  2. catch − A program catches an exception with an exception handler at the place in a program where you want to handle the problem.
