DataTable/Excel

I have a datatable populated with data from an Excel spreadsheet.

What I want to do now is loop through each row and column.

I want to find out on each row and the current column, on if the columnName is the specified start column name. It will then continue on collecting the names of columns until the specified end column name is specified.

this means that we can then go through each row but starting to get data based on the startcolumn and the end column

any ideas?

Is this what you are trying to do?

Code:

---

DataTable dt;

            dt = PopulateMyDataTable();

            int iStart = 0;
            int iEnd = 0;

            // Figure out our starting and ending columns
            for (int i = 0; i < dt.Columns.Count;i++ )
            {
                if (dt.Columns[i].ColumnName == "My Start Column")
                    iStart = i;
                if (dt.Columns[i].ColumnName == "My End Column")
                    iEnd = i;
               
            }

            if (iStart > 0 && iEnd > 0 && iStart < iEnd)
            {
                // Loop through the rows
                for (int j = 0; j < dt.Rows.Count; j++)
                {
                    DataRow objRow = dt.Rows[j];
                    for (int k = iStart; k <= iEnd; k++)
                    {
                        // Read Values from here
                    }


                }
            }
