Thread: ItemArray assignment not working as expected

Code:

protected void processDS(DataSet ds)
        {
            DataTable dt;
            int i=0;            
            
            batchLot = ds.Tables[0].Rows[0].ItemArray[0].ToString();
            dt = ds.Tables[0];
            foreach (DataRow dr in dt.Rows)
            {
                for(i=0;i<dr.ItemArray.Length;i++)
                {
                    dr.ItemArray.SetValue(dr.ItemArray[i].ToString().Replace("(M####)",batchLot),i);
                    dr.ItemArray.SetValue(dr.ItemArray[i].ToString().Replace("(DATE)",today.ToString("MMDDYY")),i);
                }
            }
        }

I'm looking in each field of each DataRow for the string values of either (M####) or (DATE) to change them to other things for display on a web page. Can anyone explain what kind of stupidity I've fallen into, please?

Nevermind, I'm a friggin moron. Following code works as expected:

Code:

protected void processDS(DataSet ds)
        {
            DataTable dt;
            int i=0;            
            
            batchLot = ds.Tables[0].Rows[0].ItemArray[0].ToString();
            dt = ds.Tables[0];
            foreach (DataRow dr in dt.Rows)
            {
                for(i=0;i<dr.ItemArray.Length;i++)
                {
                    if (dr.ItemArray.GetValue(i).ToString().Contains("(M####)"))
                        dr[i] = dr.ItemArray.GetValue(i).ToString().Replace("(M####)", batchLot);
                    if (dr.ItemArray.GetValue(i).ToString().Contains("(DATE)"))
                        dr[i] = dr.ItemArray.GetValue(i).ToString().Replace("(DATE)", today.ToString("MMddYY"));
                }
            }
        }

Thanks for your time, people!
