• String Byte 互转


    string类型转成byte[]:
    
    byte[] byteArray = System.Text.Encoding.Default.GetBytes ( str );
    
    byte[]转成string:
    
    string str = System.Text.Encoding.Default.GetString ( byteArray );
    
    string类型转成ASCII byte[]:
    
    ("01" 转成 byte[] = new byte[]{ 0x30,0x31})
    
    byte[] byteArray = System.Text.Encoding.ASCII.GetBytes ( str );
    
    ASCIIbyte[]转成string:
    
    (byte[] = new byte[]{ 0x30, 0x31} 转成"01"string str = System.Text.Encoding.ASCII.GetString ( byteArray );
    
    byte[]转16进制格式string:
    
    new byte[]{ 0x30, 0x31}转成"3031":
    
    publicstaticstring ToHexString ( byte[] bytes ) // 0xae00cf => "AE00CF "
    
    {string hexString = string.Empty;
    
    if ( bytes != null )
    
    {                
    
    StringBuilder strB = new StringBuilder ();
    
    for ( int i = 0; i < bytes.Length; i++ )
    
    {                    
    
    strB.Append ( bytes[i].ToString ( "X2" ) );                
    
    }                
    
    hexString = strB.ToString ();            
    
    }return hexString;        
    
    }
    
    16进制格式string 转byte[]:
    
    publicstaticbyte[] GetBytes(string hexString, outint discarded)
    
    {            
    
    discarded = 0;
    
    string newString = "";
    
    char c;// remove all none A-F, 0-9, charactersfor (int i=0; i<hexString.Length; i++)
    
    {              
    
      c = hexString[i];if (IsHexDigit(c))                    
    
    newString += c;
    
    else                    
    
    discarded++;            
    
    }// if odd number of characters, discard last characterif (newString.Length % 2 != 0){                discarded++;                
    
    newString = newString.Substring(0, newString.Length-1);            }
    
    int byteLength = newString.Length / 2;byte[] bytes = newbyte[byteLength];string hex;int j = 0;for (int i=0; i<bytes.Length; i++){               
    
     hex = new String(new Char[] {newString[j], newString[j+1]});               
    
     bytes[i] = HexToByte(hex);                j = j+2;           
    
     }
    
    return bytes;       
    
     }
