编码-解码统计

1，byte[] jsonBytes = Encoding.UTF8.GetBytes(json);

2，    byte[] jsonBytes = Encoding.GetEncoding("iso-8859-1").GetBytes(json);

Base64编码解码示例:https://www.cnblogs.com/dxqs/p/4670539.html

===================================================================

iso88591和utf-8编码是为了语言的需要

iso88591：英文；

utf-8：中文；

url编码：将一些http请求中不支持的特殊字符转换成支持的字符组合

base64编码：是网络上最常见的用于传输8Bit字节码的编码方式之一

=======================================================================

string name = "张";
byte[] byteArray = System.Text.Encoding.Default.GetBytes(name);
byte[] byteArray1 = System.Text.Encoding.UTF8.GetBytes(name);
byte[] byteArray2 = System.Text.Encoding.Unicode.GetBytes(name);
byte[] byteArray3 = Encoding.GetEncoding("iso-8859-1").GetBytes(name);
byte[] byteArray4 = Encoding.GetEncoding("gb2312").GetBytes(name);

After testing local default encoding is gb2312;
