Assume certain things to be true. points is the name of a variable that stores integer values, while textbox is the name of a textbox control. Implement the TryParse methods in an if-else statement that transforms the Text property of a pointsTextBox control to an int and stores the result in a points variable, as shown in the following example. If the conversion fails, an error message will be shown in a message box on the screen.
