If your RaisSalary () method is not set to static, you must instance the Testsalary class, then call RaisSalary (). If you are defined as static, there is no such problem. 2. Method or variables that need to be called directly in the Static method should be defined as static. If you don't want to be defined as static, you should new testsalary (). RaisSalary (s)
