Help Me Convert Some Code

Hello,

I have a routine that is currently in c++ and I really need to have it converted to c sharp. Could someone with a lot more knowledge then myself have a look at the code and help me out.

The code follows:

Thanks

Mike

This is the c++ code.

Code:

---

char * computeChecksum(char*  message)
        {
            static char ascii_checksum[ 5 ];
            WORD checksum    = 0
            int i                          = 0;

            while ( message[i] != '\0';
            {
              checksum += (unsigned) message[i];
              i++ ;
            }

            checksum =    -(checksum & 0xFFFF);
            sprintf( ascii_checksum, "%4.4X, checksum );
     
            return ascii_checksum;

        }

---

string computeChecksum(string m)
{
char[] message=m.ToCharArray();
static char ascii_checksum[ 5 ];
int checksum = 0
int i = 0;

while ( message[i] != '\0';
{
checksum += (int) message[i];
i++ ;
}

checksum = -(checksum & 0xFFFF);
string ascii_checksum= checksum.ToString() ;

return ascii_checksum;

}
i guess this would help you

Your C++ code was not compilable - after correcting it and converting I get:

Code:

---

private string computeChecksum_ascii_checksum = new string(new char[5]);
private string[] computeChecksum(sbyte[] message)
{
//C++ TO C# CONVERTER NOTE: This static local variable declaration (not allowed in C#) has been moved just prior to the method:
//        static sbyte ascii_checksum[5];
        ushort checksum = 0;
        int i = 0;

        while (message[i] != '\0')
        {
          checksum += (uint) message[i];
          i++;
        }

        checksum = -(checksum & 0xFFFF);
        computeChecksum_ascii_checksum = string.Format("{0,4:X4}", checksum);

        return computeChecksum_ascii_checksum;
}

Method should return String not String[]

Right you are (this is fixed in the next build).
