I am working on a function that will give me a Kermit CRC value from a HEX string. I have a piece of code in DELPHI. I am a .NET developer and need the code in C#.

function CRC_16(cadena : string):word; 
var 
valuehex : word; 
i: integer; 
CRC : word; 
Begin 
   CRC := 0; 
   for i := 1 to length(cadena) do 
   begin 
      valuehex := ((ord(cadena[i]) XOR CRC) AND $0F) * $1081; 
      CRC := CRC SHR 4; 
      CRC := CRC XOR valuehex; 
      valuehex := (((ord(cadena[i]) SHR 4) XOR LO(CRC)) AND $0F); 
      CRC := CRC SHR 4; 
      CRC := CRC XOR (valuehex * $1081); 
   end; 
  CRC_16 := (LO(CRC) SHL 8) OR HI(CRC); 
end;

I got the code from this webpage: Kermit CRC in DELPHI

I guess that Delphi function is correct. If any one can please convert the code to C# that will be great. I tried to convert to C#, but got lost in WORD data type and the LO function of Delphi. Thank you all.
