Different encoding or decoding functions must be applied according to different data contents in order to obtain the corresponding byte or string data.

Different encoding or decoding functions must be applied according to different data contents in order to obtain the corresponding byte or string data.

This program example will create four different byte data, and use three different encoding methods to convert the original byte data into a string, observe the result of the encoding function processing, the program code is as follows:

static void Main (string[] args) { byte[] ibyte1, Ibyte2, ibyte4;  byte[] ibyte3 = new byte[1024];     Ibyte1 = System.Text.Encoding.ASCII.GetBytes ("0123456789");  ibyte2 = System.Text.Encoding.ASCII.GetBytes ("Zhang Limin");  randomnumbergenerator.create (). GetBytes (Ibyte3);  ibyte4 = new byte[]{0,1,2,3,4};  show (IBYTE1);  show (IBYTE2);  show (Ibyte3);  show (IBYTE4);  console.readline (); } private static void Show (byte[] ibyte) { console.writeline ("/**********************************************/n ");  console.writeline ("ibyte[0]:" + ibyte[0]. ToString () + "n");  string ascii2str = Encoding.ASCII.GetString (ibyte);  console.writeline ("Ascii2str:" + ascii2str + "T");  console.writeline ("Ascii2str. Length: "+ ascii2str. Length + "n");  string unicode2str = Encoding.Unicode.GetString (ibyte);  console.writeline ("Unicode2str:" + unicode2str + "T");  console.writeline ("Unicode2str. Length: "+ unicode2str. Length + "n");  string utf82str = Encoding.UTF8.GetString (ibyte);  console.writeline ("Utf82str:" + utf82str + "T");  console.writeline ("Utf82str. Length: "+ utf82str. Length + "n");  byte[] Ascii2byte = Encoding.ASCII.GetBytes (ASCII2STR);  byte[] Unicode2byte = Encoding.Unicode.GetBytes (UNICODE2STR);  byte[] Utf82byte = Encoding.UTF8.GetBytes (UTF82STR);  console.writeline (Ascii2byte. Length + "" +    Unicode2byte. Length + "" + utf82byte. Length + "n");  console.writeline ("/**********************************************/n"); After executing the program, it is found that the IBYTE1 variable is encoded in ASCII or UTF8, resulting in the same string content and length as the original variable. The IBYTE2 variable is encoded in ASCII or UTF8, although the resulting string data has the same length as the original variable, but the data content differs from the original variable. After the IBYTE3 variable is ASCII encoded, the resulting string data is the same length as the original variable. After the IBYTE4 variable is encoded in ASCII or UTF8, the resulting string data is the same length as the original variable, but the data content differs from the original variable.  

As you can tell from the above results, before converting a byte to a string, you must first select the appropriate conversion function for the contents of the data before you can get the result that meets the requirements.

Different encoding or decoding functions must be applied according to different data contents in order to obtain the corresponding byte or string data.
