Summary of the use of C ＃ Jason code in TCP communication

Json Use

1、 Through management Nunet Package , download Newtonsoft.Json.DLL Assembly

2、 Import package in program ;
using Newtonsoft.Json;
3、 Create classes that need to be serialized , Design the attribute structure in the class , encapsulation , structure
4、 serialize
It is written as follows ：

  string r= JsonConvert.SerializeObject(new  Class name ( Fill in the corresponding attribute value according to the structure ));

The serialized string structure is as follows ：

Deserialization is written as follows ：

  string UserJson = "{\"UNO\":\"1\"," +
          " \"UName\":\" dragon \"," +
          " \"Uage\":\"21\"," +
          " \"Uaddress\":\" China \"," +
          " \"Uphone\":\"151 3692 3546\"}";
        User Data = JsonConvert.DeserializeObject<User>(UserJson);

Json How to use it

When used in specific projects , As receiver , Most of the data I receive is based on a format document , Write and send to me , There was no problem with it . But carefully observe the format of sending instructions in the format document , You will find some of the same fields , For example, instruction code , Machine code , Equipment address and other fields . But there are different . It can only be said that the field names with the same meaning are the same .
therefore , Think about serialization and deserialization , What happens if the properties of their corresponding objects are different .
After a series of tests , The following results are obtained ：
1、 When the attribute of the object serialized by the sender is greater than and contains the object attribute corresponding to the deserialization of the receiver , The deserialized object will only extract the value of the same field and return .
2、 When the attributes of the object serialized by the sender are smaller than those of the object deserialized by the receiver , The deserialized object will only initialize the value of the corresponding field according to the corresponding field and return .

Conclusion , The receiver doesn't have to set the same class as the sender to deserialize , Just set a class that wants to get the field as needed .

Because in the project , I need to receive different instructions with the same field , So I put all possible attributes in all instructions into one class as attributes , In this way, different instructions can be deserialized with a class .（ I'm really a little smart ） In this way, there is no need to set different classes to deserialize instructions according to the corresponding instructions , Reduce the complexity of the project .
