Hey Chandu! An assertion is code that’s used during development—usually a routine or macro—that allows a program to check itself as it runs. When an assertion is true that means everything is operating as expected. When it’s false that means it has detected an unexpected error in the code. For example if the system assumes that a customer-information file will never have more than 50000 records the program might contain an assertion that the number of records is less than or equal to 50000. As long as the number of records is less than or equal to 50000 the assertion will be silent. If it encounters more than 50000 records however it will loudly “assert” that there is an error in the program. using System; using System.Diagnostics; static class Program { static void Main() { int value = -1; // A. // If value is ever -1 then a dialog will be shown. Debug.Assert (value != -1 Value must never be -1.); // B. // If you want to only write a line use WriteLineIf. Debug.WriteLineIf (value == -1 Value is -1.); } } Result A. The dialog is displayed. B. Message is written to the Output: Value is -1. Thank you !! -------------------------------------------------- If you satisfy with the answer Please Accept it.

Hi Assert sends a strong message to the developer. An assertion interrupts normal operation of the program but does not terminate the application. The Debug.Assert method in the System.Diagnostics class provides a way to implement this.
