FIX4NET.Utils.ParseInt() Negative Numbers

[jdahl]

Not sure if it is intended, but the ParseInt function is only valid for positive integers.

This is what I mod'd it to:

public static int ParseInt(string s, int iIndex, int iLen)
{
    int iStop = iIndex + iLen;
    int iValue = 0;

    if(s[iIndex] == '-')
        iIndex++;

    for (int i = iIndex; i < iStop; i++)
        iValue = (iValue * 10) + (s[i] - 48);

    return s[iIndex] == '-' ? iValue * -1 : iValue;
}

Sorry, copied wrong code. It should be this:

public static int ParseInt(string s, int iIndex, int iLen)
        {
            int iStop = iIndex + iLen;
            int iValue = 0;
            int multiplier = 1;
           
            if(s[iIndex] == '-')
            {
                multiplier = -1;
                iIndex++;
            }

            for (int i = iIndex; i < iStop; i++)
                iValue = (iValue * 10) + (s[i] - 48);

            return multiplier < 0 ? iValue * multiplier : iValue;
        }
