Trap ~ Do not be ambiguous about the reference type!

The reference type is always mysterious because it stores the memory address. For a variable of the reference type, when you perform the value assignment operation, it is transmitted in the form of an address, when you operate on a reference type in a code segment, it will respond to the original object. Below I will talk about several common usage of the reference type:

Case 1: Will modifying the content element of a set variable affect the original object?

A: Yes, it will be reflected in the meta set.

Code:

            List<Yinyong> yiyi =  List<Yinyong> {  Yinyong { ID = , Name =  },  Yinyong { ID = , Name = ].Name =             Console.WriteLine(yiyi[

Scenario 2: After defining a set variable, add some of its elements to another set, and modify its elements in another set, will it be reflected in the original set?

A: Yes, it will be reflected in the meta set.

Code:

            List<Yinyong> yiyi =  List<Yinyong> {  Yinyong { ID = , Name =  },  Yinyong { ID = , Name = <Yinyong> temp =  List<Yinyong>=> i.ID ==  ( item = 

Case 3: After defining the set variable, pass it as a parameter to other methods. Will the modification of this object in other methods be reflected in the original set of the original method?

A: Yes, it will be reflected in the meta set.

Code:

    Main(<Yinyong> yiyi =  List<Yinyong> {  Yinyong { ID = , Name =  },  Yinyong { ID = , Name =                              ModifySet(List<Yinyong>].Name = 

 

Well, after mastering the above three points, we will be more comfortable writing code. Only by mastering the basic knowledge can we design better programs!
