C byte array (byte []) and string are converted to each other

adopt C# Medium system.text.encoding The encoding of the obtained string can be ASCII,DEFAULT,utf-8 And other ways , For English, there is no big difference between these codes , Chinese is very different , among DEFAULT What has been taken is GB2312, It can be confirmed in the following ways , After the program runs, you will find bufOfGB and buf It's the same
 

                string str = "hello, My motherland ";
                byte[] bufOfGB = System.Text.Encoding.GetEncoding("gb2312").GetBytes(str);
                Array.ForEach(bufOfGB,m=>Console.WriteLine(m));
                Console.WriteLine(System.Text.Encoding.Default);
                byte[] buf = System.Text.Encoding.Default.GetBytes(str);
                Array.ForEach(buf,m=>Console.WriteLine(m));
                Console.WriteLine("-------------");
                byte[] bufOfASCII = System.Text.Encoding.ASCII.GetBytes(str);
                Array.ForEach(bufOfASCII,m=>Console.WriteLine(m));
                Console.WriteLine("-------------");
                byte[] bufOfUTF = System.Text.Encoding.UTF8.GetBytes(str);
                Array.ForEach(bufOfUTF,m=>Console.WriteLine(m));
                Console.WriteLine("-------------");

byte[] byteArray ={43,45,67,88,23,1f}
string str = System.Text.Encoding.Default.GetString(byteArray);
