在vb.net中把string轉化成byte數組
dim  StrFtpUpdateIniDest  as  string  ="C:\AVM\PlayList\New\"  
Dim  sms()  As  Byte=System.Text.Encoding.default.getbytes(StrFtpUpdateIniDest)  

1、
        System.Text.UnicodeEncoding converter = new System.Text.UnicodeEncoding();
        byte[] inputBytes =converter.GetBytes(inputString);
        string  inputString = converter.GetString(inputBytes);
2、
        string inputString = System.Convert.ToBase64String(inputBytes);
        byte[] inputBytes = System.Convert.FromBase64String(inputString);

1、
        System.Text.UnicodeEncoding converter = new System.Text.UnicodeEncoding();
        byte[] inputBytes =converter.GetBytes(inputString);
        string  inputString = converter.GetString(inputBytes);
2、
        string inputString = System.Convert.ToBase64String(inputBytes);
        byte[] inputBytes = System.Convert.FromBase64String(inputString);
