Unit Testing for 3.Visual StudioThere are many. NET unit test packages, many of which are open source and free. This article intends to use the built-in unit test support that is included with Visual Studio, but some others. NET unit Test package is also available.To demonstrate unit test support for Visual Studio, this example intends to add a new implementation of the Idiscounthelper interface to the sample project. Under the Models folder, create a new class file MinimumDiscountHelper.cs:name

TemplateField consolidates data such as UnitPrice, UnitsInStock, and UnitsOnOrder and is displayed on a DetailsView line. The first TemplateField will display the discontinued data, but the formatting method will be used to show "YES" when there is a discount, otherwise the "NO" is displayed.

In this example, we start with a simple calculation: // Double price () {// price = basePrice-quantity discount + shippingreturn _ quantity * _ itemPrice-Math. max (0, _ quantity-800) * _ itemPrice * 0.15 + Math. min (_ quantity * _ itemPrice * 0.25, 100 );}T

Because this will be the original value of the parameter is missing, we need to introduce a temporary variable, and then the temporary variable to operate.1.

simple judgment. to process more complex logic judgment, you need to use nested if statements. In the following example, the prompt information should be displayed not only when the if condition $ today = Sunday is true, but also when each condition is true.If ($ today = Sunday ){Echo" ";Echo "today is not going to work! ";} Else {If ($ time = "9:00 ")Echo "it's time to get up! ";If ($ today = "Saturday ")Echo "the weekend is over! ";} 3. elseif statement When you need to make multiple decision

control should be the same as the abstract class, or be more relaxed. an abstract class contains at least one abstract method. Interface Using interfaces, you can specify the methods that a class must implement, but you do not need to define the specific content of these methods. All methods defined must be public and the method is empty. A constant can be defined, but no attribute exists. The implementation of the interface (implements) must implement all methods and multiple interfaces can be
