Hi,

In the following code I am writing all the 2nd row of dataset into excel file.

C#

int i = 1;
foreach (DataRow row in lstDS[0].Tables[0].Rows)
{
   xlWorkSheet1.Cells[i, 1] = row[2];
   i++;
}

But I need to filter them in a way that only strings starting with GW should be written into excel sheet????

Thanks
John

C#

foreach (DataRow row in lstDS[0].Tables[0].Rows)
{
    string fieldFromDB=row[2].toString();
    if (fieldFromDB.StartsWith("GW"))
    {
        xlWorkSheet1.Cells[i, 1] = row[2];
        i++;
   }
}

Hi,

Thank you for your reply. This is working fine.

I need to extract the column of the data table if the string of the row matches with GW

How this can be done???

I'm not sure if I fully understand your question. Do you mean column name or caption?
You can access column object and properties within your loop with code like:
row.Table.Columns[2].ColumnName;
row.Table.Columns[2].Caption;

Well, I would start with this Google search:
Google Search for String.StartsWith[^]

This will tell you how to use the "StartsWith" command on a string.

You can then use this with the contents of row[2] and see if they meet your criteria and in turn add it to the cell. then loop.

Hope that helps :-)

Hi there,
You can simply use text spliter method;

C#

string[] st = System.Text.RegularExpressions.Regex.Split(row, "GW");

Good Luck,
