Stream, byte, character, string in C #

First, you must understand what they are composed:

Stream: Binary

Byte: unsigned integer

Character: unicode encoded character

String: Multiple Unicode characters

 

In. net, how can they be converted?

Generally, the following rules are observed:

Stream-> byte array-> character array-> string

 

The following describes the conversion syntax.

Stream-> byte array

Memorystream MS = new memorystream ();

Byte [] buffer = new byte [Ms. Length];

Ms. Read (buffer, 0, (INT) ms. Length );

 

Byte array-> stream

Byte [] buffer = new byte [10];

Memorystream MS = new memorystream (buffer );

 

Byte array-> character array

1.

Byte [] buffer = new byte [10];

Char [] CH = new asciiencoding (). getchars (buffer );

// Or: Char [] CH = encoding. utf8.getchars (buffer)

2.

Byte [] buffer = new byte [10];

Char [] CH = new char [10];

For (INT I = 0; I <buffer. length; I ++)

{

Ch [I] = convert. tochar (buffer [I]);

}

 

Character array-> byte array

1.

Char [] CH = new char [10];

Byte [] buffer = new asciiencoding (). getbytes (CH );

// Or: byte [] buffer = encoding. utf8.getbytes (CH)

2.

Char [] CH = new char [10];

Byte [] buffer = new byte [10];

For (INT I = 0; I <Ch. length; I ++)

{

Buffer [I] = convert. tobyte (CH [I]);

}

 

Character array-> string

Char [] CH = new char [10];

String STR = new string (CH );

 

String> character array

String STR = "ABCDE ";

Char [] CH = Str. tochararray ();

 

Byte array-> string

Byte [] buffer = new byte [10];

String STR = system. Text. encoding. utf8.getstring (buffer );

// Or: String STR = new asciiencoding (). getstring (buffer );

 

String> byte array

String STR = "ABCDE ";

Byte [] buffer = system. Text. encoding. utf8.getbytes (STR );

// Or: byte [] buffer = new asciiencoding (). getbytes (STR );

 

Note: The convert class and the class in the system. Text namespace are used. encoding is a static class, asciiencoding is an entity class, and the methods are the same!
