I have a combobox cbpaymenttype have values like(DD , CASH ,CARD)

    I have list view  Named as listviewcashmembers

 with items lastname(xxxx),
           firstname(xxx),
           postcode(xxx),

I have done like this for generating pdf when we click on the print button and appropriate selection of Combo box(cbpaymenttype.Text)

code in main form is like this and this code will calling another class also

      private void btnPrint_Click(object sender, EventArgs e)
      {
                private const string DDPROVIDERMEMBERS_PATH = @"xxxxxxxxxx_{0}";

              if (cbpaymentty开发者_如何学编程pe.Text == "DD ")
              {
                string path = string.Format(DDMEMBERSREPORT_PATH, DateTime.Now.ToString("ddMMyyyyHHmm"));
                List<DDmembersmonthlyreport> ddmembersreportmembers = new List<DDmembersmonthlyreport>();
                if (lstviewcashmembers.Items.Count != 0)
                {
                    foreach (ListViewItem item in lstviewcashmembers.Items)
                    {
                        DDmembersmonthlyreport ddmembers = new DDmembersmonthlyreport();
                        ddmembers.member_Lastname = item.SubItems[1].Text;
                        ddmembers.member_Firstname = item.SubItems[2].Text;
                        ddmembers.Postcode = item.SubItems[3].Text;
                        ddmembers.ddReference = item.SubItems[4].Text;
                        ddmembers.ddprovider = item.SubItems[5].Text;
                        ddmembers.Monthlyamount = Convert.ToDecimal(item.SubItems[6].Text);
                        ddmembers.MembershipType = item.SubItems[7].Text;
                        ddmembers.Status = item.SubItems[8].Text;
                        ddmembers.Enddate = Convert.ToDateTime(item.SubItems[9].Text);
                        ddmembers.paymenttype = item.SubItems[10].Text;

                        ddmembersreportmembers.Add(ddmembers);

                    }

                    new PdfDDMembersMonthlyValueReport(ddmembersreportmembers, new Company(mf.gBaseUrl).GetSingleLineCompanyDetails(), path);
                    System.Diagnostics.Process.Start("explorer.exe", path);
                }


          if (cbpaymenttype.Text == "cash")
          {   

                   xxxxxxxxxx
              new PdfCashMembersMonthlyValueReport(ddmembersreportmembers, new                 Company(mf.gBaseUrl).GetSingleLineCompanyDetails(), path);
                    System.Diagnostics.Process.Start("explorer.exe", path);



         }
}

like this i have done for all options in combobox (cbpaymenttype)

I have created class like this

  public class DDmembersmonthlyreport
  {
    public string member_Lastname;
    public string member_Firstname;
    public string Postcode;
    public string ddReference;
    public string ddprovider;
    public decimal Monthlyamount;
    public string MembershipType;
    public string Status;
    public DateTime Enddate;
    public string paymenttype;

}

        pdfRenderer.Document = ddreportdoc;

        if (!Directory.Exists(exportpath))
            Directory.CreateDirectory(exportpath);


        pdfRenderer.RenderDocument();

        pdfRenderer.Save(String.Format(@"{0}\DD members.pdf", exportpath));

    }

I have created this classes for diffrent combobox options(cbpaymenttype) for printing listviewitems for selection of combobxitems

My problem is i want to use the only single class for different types of options in "cbpaymenttype"

would any one pls give idea about this using single class for different type of options for cbpaymenttype

is it possible to pass the value of cbpaymenttype to this "ddmembers.paymenttype"

Many Thanks

With the information give, this is the best I can offer...

public enum PaymentType { Other, DD, Cash, Card }

public class DDmembersmonthlyreport
{
    ...
    public PaymentType paymenttype;
    // Edit
    public void UpdatePaymentType(string fromCombobox)
    {
        paymenttype = (PaymentType)Enum.Parse(typeof(PaymentType), fromCombobox);
    }
}
