type of conditional expression cannot be determined

using Microsoft.visualBasic;

private void GetData(ref DataTable dtData, ref DataTable dtData2)
 {

        DataRow dr = null;
        string strFilter = null;
        int intVPLCs = 0;
        int intTotVPLCS = 0;
        int intMSCs = 0;
        int intTotMsCs = 0;
        int intBSCs = 0;
        int intTotBSCs = 0;
        int intVPLScnQty = 0;
        int intTotVPLScnQty = 0;

        try
        {
            foreach (DataRow drWithinLoop in dtData.Rows)
            {
                dr = drWithinLoop;
               drWithinLoop["Vpl"] = (intMSCs == 0) ? 0 : Microsoft.VisualBasic.Strings.FormatNumber(((intVPLCs + intVPLScnQty) * 100 / (double)intMSCs), 0,   Microsoft.VisualBasic.TriState.True, Microsoft.VisualBasic.TriState.UseDefault, Microsoft.VisualBasic.TriState.UseDefault);
           }

catch(Exception Ex)

{

}

}

}

I am getting Exception type of conditional expression cannot be determined because there is no implicit conversion int to string

How can i solve that issue.

Thanks
