点击打印按钮时，系统崩溃

我已经这样做了在运行时生成PDF B中的过程是这样的，当我点击与文件夹中生成的PDF打印按钮时，我上的打印按钮$ B $点击。

I have done like this for generating pdf at runtime when i click on the print button The process is like this when I click on the print button the pdf is generated with folder.

有关，我做过这样的：

private void btnPrint_Click(object sender, EventArgs e)
{

    private const string PAYMENT_PATH = @"c:\xxxxx\xxxxx\paymentType_{0}";

    btnPrint.Visible = true;
    btnPrint.Enabled = true;

    string pay = cbpaymenttype.Text;
    string dds = cbddprovider.Text;

    string path = String.Format(PAYMENT_PATH, DateTime.Now.ToString("ddMMyyyyHHmm"));

    //List<paymenttypeprint> paymenttype = new List<paymenttypeprint>();

    List<printfunctions> printfunction = new List<printfunctions>();
    foreach (ListViewItem item in lstviewcashmembers.Items)
    {

        printfunctions allpayments = new printfunctions();
        allpayments.member_Lastname = item.SubItems[1].Text;
        allpayments.member_Firstname = item.SubItems[2].Text;
        allpayments.Postcode = item.SubItems[3].Text;
        allpayments.ddReference = item.SubItems[4].Text;
        allpayments.ddprovider = item.SubItems[5].Text;
        allpayments.Monthlyamount = Convert.ToDecimal(item.SubItems[6].Text);
        allpayments.MembershipType = item.SubItems[7].Text;
        allpayments.Status = item.SubItems[8].Text;
        allpayments.Enddate = Convert.ToDateTime(item.SubItems[9].Text);
        allpayments.paymentmethods = item.SubItems[10].Text;
        printfunction.Add(allpayments);
    }

    new printFunction(printfunction, new Company(mf.gBaseUrl).GetSingleLineCompanyDetails(), path, pay, dds);

    System.Diagnostics.Process.Start("explorer.exe", path);
}

我已经创建的类 printfunctions 是这样的：

其工作时，的ListView lstviewcashmembers拥有高达100或300行，但是当的ListView lstviewcashmembers有1600行的工作不细

Its working fine when the ListView lstviewcashmembers has rows upto 100 or 300, but its not working when the ListView lstviewcashmembers has 1600 rows.

在该行系统崩溃：

pdfRenderer.RenderDocument();

执行不进入下一行，并没有显示也是系统刚刚崩溃任何异常当我点击打印按钮，如果的ListView 有1600行。

这有什么错在我的代码使用MigraDoc和PDFsharp库在运行时生成PDF？

Is there anything wrong in my code for generating PDF at run time using MigraDoc and PDFsharp libraries?

会有人请帮助这个......

Would anyone please help on this .....

非常感谢........

Many thanks........

 MODIFIED :  It will take four minutes  for generating pdf so how should I reduce this time 

将在这个任何一个帮助

非常感谢
