vb.net - Get hashed Password using same concept in c# , vb give different results -

i have vb code apply hashing string , tried same concept using c# give me different result although when debug code using same value , values of myhash,bytearray,hasharray in c# project same vb project final returned string different here code in vb:

       dim hashkey(23) byte public function stringhash(byval strstring string) string     if strstring.trim = "" return ""     try         generatekey()         dim myhash hashalgorithm = new mactripledes(hashkey)         dim bytearray() byte         bytearray = asciistringtobytearray(strstring)         dim hasharray() byte         hasharray = myhash.computehash(bytearray)         hasharray = removequotes(hasharray)         return bytearraytoasciistring(hasharray)     catch ex exception         return ""     end try end function  public function generatekey() byte()     integer = 0 hashkey.length - 1         hashkey(i) = * 3 + 19     next     return hashkey end function public function asciistringtobytearray(byval strstring string) byte()     dim e encoding = encoding.ascii     'dim result(strstring.length - 1) byte     dim result() byte     result = e.getbytes(strstring)     return result end function public function removequotes(byref bytearray() byte) byte()     dim intarraylength integer     intarraylength = bytearray.length     dim result(intarraylength - 1) byte     integer = 0 bytearray.length - 1         if bytearray(i) <> 34 , bytearray(i) <> 39             result(i) = bytearray(i)         else             result(i) = 32         end if     next     return result end function public function bytearraytoasciistring(byval bytearray() byte) string     return system.text.encoding.ascii.getstring(bytearray) end function 

the code in c# :

    byte[] hashkey = new byte[24];     public string stringhash(string strstring)     {         if ((strstring == ""))         {             return "";         }         try         {             generatekey();             hashalgorithm myhash = new mactripledes(hashkey);             byte[] bytearray;             bytearray = asciistringtobytearray(strstring);             byte[] hasharray;             hasharray = myhash.computehash(bytearray);             hasharray = removequotes(ref hasharray);             return bytearraytoasciistring(hasharray);         }         catch (exception ex)         {             return "";         }      }     public byte[] generatekey()     {         (int = 0; (i <= (hashkey.length - 1)); i++)         {             //hashkey[i] =  bitconverter.getbytes(i * 3 + 19)[0];             hashkey[i] = (byte)(i * 3 + 19);         }          return hashkey;     }      public byte[] asciistringtobytearray(string strstring)     {         encoding e = encoding.ascii;         // dim result(strstring.length - 1) byte         byte[] result;         result = e.getbytes(strstring);         return result;     }     public byte[] removequotes(ref byte[] bytearray)     {         int intarraylength;         intarraylength = bytearray.length;         byte[] result = new byte[intarraylength];          (int = 0; (i <= (bytearray.length - 1)); i++)         {             if (((bytearray[i] != 34) && (bytearray[i] != 39)))             {                 result[i] = bytearray[i];             }             else {                 result[i] = 32;             }          }          return result;     }      public string bytearraytoasciistring(byte[] bytearray)     {         return system.text.encoding.ascii.getstring(bytearray);     }
