Question

I have a method that calls a Proc ad returns the data. But I want to call the method and loop through all the results and use the results to plug into an Excel document. I can’t seem to figure out how to loop through results coming from the method call. This is my method:

    public DataView GetCoupons()
    {
        string connStr = ConfigurationManager.ConnectionStrings["SiteSqlServer"].ConnectionString;
        SqlConnection conn = new SqlConnection(connStr);
        SqlCommand cmd = new SqlCommand("CPC_GetAllCoupons", conn);
        cmd.CommandType = CommandType.StoredProcedure;

        //make the dap & ds
        SqlDataAdapter dap = new System.Data.SqlClient.SqlDataAdapter(cmd);
        DataSet ds = new DataSet();

        //open con
        if (conn.State == ConnectionState.Closed)
            conn.Open();

        //get the data
        dap.Fill(ds);

        //close the conn and return
        if (conn.State == ConnectionState.Open)
            conn.Close();

        return ds.Tables[0].DefaultView;
   }

So I want to call that method and get all the results and loop through the results. How would I go about doing that?

Thanks!

Answer 1

Something like this, should be enough

foreach (DataRowView rowView in dv) //where dv is your DataView
{
    DataRow row = rowView.Row;

    // Do your stuff here
}

Hope this helps.
