C # strings and byte arrays are converted to each other

Summary: It is unlikely that a method can be found directly from the System.String class to convert between a string and a byte array. To convert between them, you need to use a different type: System.Text.Encoding. This type provides a way to convert C # strings to byte arrays, as well as to convert C # byte arrays into strings.

The default constructor for the System.Text.Encoding type is not available, but the type provides several default static Properties. As follows:

1   //2         //summary:3         //gets the encoding of the ASCII (7-bit) character Set. 4         //5         //return result:6         //encoding of the ASCII (7-bit) character Set. 7          public StaticEncoding ASCII {Get; }8         //9         //summary:Ten         //gets the encoding of the UTF-16 format using the Big Endian byte order.  one         // a         //return result: -         //gets the encoded object in UTF-16 format that uses the Big Endian byte order.  -          public StaticEncoding Bigendianunicode {Get; } the         // -         //summary: -         //gets the encoding of the operating System's current ANSI code Page.  -         // +         //return result: -         //The encoding of the operating System's current ANSI code Page.  +          public StaticEncoding Default {Get; } a         // at         //summary: -         //gets the encoding in UTF-16 format using the Little-endian byte order.  -         // -         //return result: -         //encode in UTF-16 format using the Little-endian byte order.  -          public StaticEncoding Unicode {Get; } in         // -         //summary: to         //gets the encoding in UTF-32 format using the Little-endian byte order.  +         // -         //return result: the         //encodes an object in UTF-32 format using the Little-endian byte order.  *          public StaticEncoding UTF32 {Get; } $         //Panax Notoginseng         //summary: -         //gets the encoding for the UTF-7 format.  the         // +         //return result: a         //encoding of the UTF-7 format.  the          public StaticEncoding UTF7 {Get; } +         // -         //summary: $         //gets the encoding for the UTF-8 format.  $         // -         //return result: -         //encoding of the UTF-8 format.  the          public StaticEncoding UTF8 {Get; }

System.Text.Encoding

one, the string is converted into a byte array

1  //System.Text.Encoding.GetBytes (String Str)2             //1. String conversion byte array3 4             stringSTR1 ="character string1";5             varStrToBytes1 =System.Text.Encoding.UTF8.GetBytes (str1);6 7             stringSTR2 ="character string2";8             varStrToBytes2 =System.Text.Encoding.Default.GetBytes (str2);9 Ten             stringSTR3 ="character String3"; one             varStrToBytes3 =System.Text.Encoding.Unicode.GetBytes (str3); a  -             stringSTR4 ="character String4"; -             varStrToBytes4 =System.Text.Encoding.ASCII.GetBytes (str4); the  -             stringSTR5 ="character String5"; -             varSTRTOBYTES5 =System.Text.Encoding.UTF32.GetBytes (str5); -  +             stringSTR6 ="character String6"; -             varSTRTOBYTES6 = System.Text.Encoding.UTF7.GetBytes (str6);

System.Text.Encoding.GetBytes (String Str)

second, byte arrays are converted into strings

1  //2. byte array converted to string2 3Console.Write ("StrToBytes1 is converted to a string using UTF8 encoding:");4             varByteToString1 =System.Text.Encoding.UTF8.GetString (strToBytes1);5 Console.WriteLine (byteToString1);6Console.Write ("StrToBytes1 is converted to a string using the default Encoding:");7             varByteToString2 =System.Text.Encoding.Default.GetString (strToBytes2);8 Console.WriteLine (byteToString2);9Console.Write ("StrToBytes1 is converted to a string using Unicode encoding:");Ten             varByteToString3 =System.Text.Encoding.Unicode.GetString (strToBytes3); one Console.WriteLine (byteToString3); aConsole.Write ("StrToBytes1 is converted to a string using ASCII encoding:"); -             varByteToString4 =System.Text.Encoding.ASCII.GetString (strToBytes4); - Console.WriteLine (byteToString4); theConsole.Write ("StrToBytes1 is converted to a string using UTF32 encoding:"); -             varByteToString5 =System.Text.Encoding.UTF32.GetString (strToBytes5); - Console.WriteLine (byteToString5); -Console.Write ("StrToBytes1 is converted to a string using UTF7 encoding:"); +             varByteToString6 =System.Text.Encoding.UTF7.GetString (strToBytes6); -Console.WriteLine (byteToString6);

System.Text.Encoding.GetString (byte[] Byte)

three, string conversion into a stream

1   // System.IO.MemoryStream 2             // 3. String conversion to stream 3             new  System.IO.MemoryStream (strToBytes2); 4             New System.IO.MemoryStream (convert.frombase64string (str1));

System.IO.MemoryStream

Iv. transfer to a string

1   // System.IO.MemoryStream 2             // 4. Transfer to string 3             var memoryToString1 = System.Text.Encoding.Default.GetString (ms2 . ToArray ()); 4             var memoryToString2 = convert.tobase64string (ms2. ToArray ());

System.IO.MemoryStream

V. Convert a byte array into a stream

1   // 5. byte array converted to stream 2             new  System.IO.MemoryStream (strToBytes1); 3 4             New 0, strtobytes1.length);

converting a byte array into a stream

six, Transfer to byte array

1 // 6. Transfer to byte array 23byte[] bt = ms3. ToArray (); 4 5 New System.IO.MemoryStream (); 6 0, (int) ms4. Length);
