Visual Studio class designer of many skills, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can get something.

Visual Studio has a lot to learn, here we mainly introduce Visual Studio class designer, Visual Studio class designer is a visual code design tool, with the integrated design effect of .NET Framework, including the introduction of visual inheritance hierarchy and so on. The visual effect of the class designer is closely related to the common language runtime. CLR graphics, such as classes, structures, and interfaces, are represented visually and uniquely and are used to identify them. Moreover, the terms in the figure are language-specific, for example, in Visual Basic, you can use Public, Private, and Friend access levels, while in C #, they will be displayed as public, private, and internal. Tightly integrated with CLR, Class designer has become an ideal tool for designing classes using the .NET Framework.

The Visual Studio class designer is useful throughout the development cycle, providing functionality in all of the major aspects mentioned above. For example:

1) understand existing code: the Visual Studio Class designer allows you to quickly and easily examine relationships between classes. You can check not only the inheritance hierarchy of existing code, but also reference types and NET assemblies, which allows you to visually browse and familiarize yourself with existing types.

2) Class design: the Visual Studio class designer helps to quickly design classes and class hierarchies. Using the familiar drag-and-drop functionality, you can edit the class through the diagram while synchronizing with the code editor. Changes to the class diagram are directly reflected in the code, and vice versa. The class diagram always shows a real-time view of the code.

3) Review and ReFactor Code: the Visual Studio Visual Class designer is a powerful tool for code review and refactoring. You can add comments to an existing code diagram for later operation, and use built-in code refactoring features to quickly and easily complete day-to-day tasks such as renaming symbols or encapsulating fields in attributes.

4) document class diagrams: class diagrams can be displayed in different ways, such as printing or saving as images for display in HTML pages or Microsoft PowerPoint presentations.

Create a class using the Visual Studio Class designer

The Visual Studio Class designer makes it very easy to create and configure classes in your project. The class diagram is actually a real-time view of the code. Changes to the diagram are automatically synchronized with the code, and vice versa. Drag a class from the toolbox to the surface of the Class designer to create a simple class. Once you have created a class in your project, you can open the code editor and add code directly to the new class. Any changes you make will be reflected in the class diagram.

Once you have created a class, you can use the Class details window to add members. For example, to add a method, click "" in the Class details window and type a name for the method. You can then indicate the return type, access level, and add any comments about the method. Once you have created a method, you can add parameters to the method name (much like the process of adding a method)-first indicate the parameter name, and then indicate the type, modifier, and any comments. You can add properties, fields, and events as you add methods. The process of using the tree control editing method is very similar to typing in the code editor-all use the same keystrokes to navigate between units, and you can all use IntelliSense help.

Implementation interface

You can easily implement an interface in a class using the Visual Studio Class designer. In fact, if the interface is displayed on the surface of the class designer, you can use the process used to inherit the class to implement the interface, that is, draw an inheritance line from the class to the interface. If the interface is not displayed in Class designer, it is still easy to implement. Simply drag the interface from Class view to the class you want to implement. The method stub for the method defined in the interface is automatically generated. Once the interface is implemented, you can add specific implementation code to the code editor.

Visual inheritance hierarchy

You can use the Visual Studio Class designer to visualize the inheritance hierarchy in your project. To display the base class of an inherited class, right-click the top area of the class, and click Show Base Class. The base class appears on the chart. To display classes that inherit from an existing class, right-click the top area of the class, and click Show derived types. A derived class appears on the diagram and is connected to the class through an inheritance line.
