Usually type converter in socket transfor

As a chsarp developer, you must have learned the socket, and you know that the data transfor by network shoshould be rely on byte or XML.

There I will give the usually type converter in socket transfor

 

1: String byte [] (use to fransfor message in socket)

(1): String convert to byte []

String STR = "Wulong ";

Byte [] bytearray = system. Text. encoding. Default. getbytes (STR );

// You also cocould select your own encode Accoding to the requirement of Project

 

(2) byte [] convert to string

Byte [] bytearray; // you can get it by the socket, then convert to string

String STR = system. Text. encoding. Default. getstring (bytearray );

 

2: file byte [] (use to file transfor in socket)

(1): file to byte []

String filename = "";

Filestream = new filestream (filename, filemode. Open, fileaccess. Read );

Binaryreader = new binaryreader (filestream );

Binaryreader. basestream. Seek (0, seekorigin. Begin );

Byte [] bytes = binaryreader. readbytes (INT) binaryreader. basestream. Length );

(2): byte [] to filestream

Byte [] bytes;

Filestream = new filestream (filename, filemode. Open, fileaccess. Read );

Filestream. Write (bytes, 0, bytes. Length );

Then you coshould deal with the filestream

3: Image byte [] (use transfor image in socket)

(1): image to byte []

Image image = image. fromfile ("filepath ");
Memorystream MS = new memorystream ();
Image. Save (MS, system. Drawing. imaging. imageformat. PNG );
Byte [] byteimage = Ms. getbuffer ();

(2): byte [] to image

Byte [] byteimage;

Memorystream MS = new memorystream (byteimage );
Image imagegetbybytes = image. fromstream (MS );
