Conversion of C # strings, byte arrays, and memory streams-top of the IT wave

Defines the string variable as str, the memory rheology is MS, and the bit array is BT

1. String = = array of bits

(1)byte[] Bt=system.text.encoding.default.getbytes (" string");(2)byte[] bt= Convert.frombase64string (" string");       

Add:

System.Text.Encoding.Unicode.GetBytes (str); System.Text.Encoding.UTF8.GetBytes (str); System.Text.Encoding.GetEncoding ("// Specify encoding method  

string str =  " China? Ss123? "; byte[] bytes = System.Text.Encoding.Default.GetBytes (str); //gb2312 encoded Chinese characters accounted for 2 bytes, English alphabet accounted for 1 bytes bytes length 12string s = System.Text.Encoding.Default.GetString (new byte[] {Bytes[0],bytes[1]}); // decoded to "medium"          

byte[] bytes = {// Result: abcdef ASCII code table 

Common methods:

GetString  is overloaded. When overridden in a derived class, decodes a sequence of bytes into a string. GetChars   is overloaded. When overridden in a derived class, decodes a sequence of bytes into a set of characters. GetBytes   is overloaded. When overridden in a derived class, encodes a set of characters into a sequence of bytes. GetByteCount  is overloaded. When overridden in a derived class, calculates the number of bytes produced by encoding a set of characters. GetCharCount  is overloaded. When overridden in a derived class, calculates the number of characters produced by decoding a sequence of bytes. Getdecoder When overridden in a derived class, gets a decoder that converts an encoded sequence of bytes into a sequence of characters. Getencoder When overridden in a derived class, gets a decoder that converts a sequence of Unicode characters to an encoded sequence of bytes

2. Bit array = string

(1)string str=system.text.encoding.default.getstring (BT);(2)string str=convert.tobase64string (BT );

3. String = Flow

(1) MemoryStream ms=new MemoryStream (System.Text.Encoding.  Default.getbytes (" string")));(2) MemoryStream ms=new MemoryStream (Convert.frombase64string (" string "));        

4. Stream = = string

(1)string str=convert.tobase64string (Ms. ToArray ());(2)string str=system.text.encoding.default.getstring (Ms. ToArray ());   

5. Array of bits = flow

(1) MemoryStream ms=new MemoryStream (BT);(2) MemoryStream ms=new MemoryStream (); Ms. Read (BT,0,BT. lenght);    

6. Stream = array of bits

(1)byte[] Bt=ms. ToArray ();(2) MemoryStream ms=new MemoryStream (); Ms. Write (BT,0,ms. Length);
