Open the Call Hierarchy view
Click "View" > "Call Hierarchy" on the menu bar to check in the Call Hierarchy view.
View member calls
In the code editing window, right-click the class member you want to view, and then select "View Call Hierarchy" to view the calls of the member.
After clicking this button, the Call Hierarchy window will automatically open. There is no need to open the window in advance.
Remove a member from view
We can observe the calls of many members in the call hierarchy at the same time. So what should we do if we don't want to see the calls of a certain member? At this time, just click the red × in the toolbar, which is the "Remove Root" button, to remove the currently selected member.
View detailed calling location
In the call hierarchy window, we double-click a reference to the member of interest to jump to the corresponding call area, or we can click the "Switch Details Pane" button on the toolbar to open a detailed window. , when we click the reference of a member, we can see which file and line of code the reference is in.

Introduction to the Call Hierarchy window
Call Hierarchy allows us to view the calling relationship of members in the code.
Use Call Hierarchy to analyze calls to a member.
In the Call Hierarchy window, a member's calling tree (or called tree) is displayed. The root node of the tree represents the selected member itself, and each child node represents the place where that member is called. By expanding or collapsing nodes, we can gain insight into the calling relationships of members.
Right-click a member and select Go to Definition to jump to the member's definition. Or double-click.
By using Call Hierarchy, you can more easily understand and analyze the calling relationships between members, speed up code debugging, and improve code maintainability.
In addition, Visual Studio also provides many other tools, such as the class designer, which is used to visually design and edit classes and the relationships between classes.
Class Designer allows us to graphically create and modify elements such as classes, interfaces, methods, and properties without directly editing the source code. Drag and drop classes and class members, and set their properties and relationships to visually build the structure of your class.
At the same time, the class designer also helps to better understand and visualize the code structure. It plays an important auxiliary role in object-oriented programming, allowing us to design and modify class relationships more conveniently.
With the combination of Call Hierarchy and class designer, we can better understand and maintain the calling relationship and class structure of the code. This is helpful at work.
