//  Let's say we want to append the following row:
//  yelp,Yelp,,web,San Francisco,CA,1-Jul-04,1000000,USD,a

//  If we have the row as-is, we could do this:
Chilkat.Csv csvTemp = new Chilkat.Csv();
success = csvTemp.LoadFromString("yelp,Yelp,,web,San Francisco,CA,1-Jul-04,1000000,USD,a");
int numCols = csvTemp.NumColumns;

int row = csv.NumRows;
while (i < numCols) {
    csv.SetCell(row,i,csvTemp.GetCell(0,i));
    i = i + 1;
}

//  Show the updated CSV:
Debug.WriteLine(csv.SaveToString());

//  Output should be:
