C # Newtonsoft. Json serialization of byte type data-CodePudding

I use c # Newtonsoft. Json serialization Json data communicate with the server, but found that the serialization with Chinese utf8 string, became GBK code automatically, and then I direct serialized byte type character array, the serialized into base64 encoded automatically, and how to correct serialized as utf8 string,

 

Encoding utf8 Encoding of=. Utf8; 
Encoding defalutEnc=Encoding. The Default; 
Byte [] unicodeBytes=defalutEnc. GetBytes (" drops drop 123 ");//Chinese string 
Byte [] asciiBytes=Encoding. The Convert (defalutEnc utf8, unicodeBytes);//utf8 byte array 

Var sendText=utf8. Get string (asciiBytes);//utf8 string 

Var data=https://bbs.csdn.net/topics/new 
{
Type=5000, 
The content=asciiBytes//1. Direct serialization byte 
//the content=sendText//2. Serialization utf8 string 
}; 

//directly serialized byte, dataStr inside the content into base64 encoded data 
//serialization utf8 string, dataStr inside the content into GBK encoding data 
Var dataStr=JsonConvert. SerializeObject (data); 

//send json string 
SendJsonStr (dataStr);
