我这样做是为了在运行时生成pdf，当我点击打印按钮时 当我点击打印按钮时，这个过程是这样的，pdf是用文件夹生成的。
为此，我这样做了：
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);
}
我已经创建了这样的类printfunctions：

当ListView lstviewcashmembers的行数达到100或300时，它的工作正常，但当ListView lstviewcashmembers有1600行时它不起作用。
系统在此行崩溃：
pdfRenderer.RenderDocument();
执行没有进入下一行，它也没有显示任何异常，当我点击打印按钮并且ListView有1600行时系统崩溃了。
我的代码在运行时使用MigraDoc和PDFsharp库生成PDF有什么问题吗？
有人请帮忙吗.....
非常感谢........
MODIFIED : It will take four minutes for generating pdf so how should I reduce this time
对此有任何帮助
非常感谢

在VS中启用异常处理，例如here，您将获得确切的异常描述。查看您的问题描述听起来像这可能是行数限制。顺便提一下，查看链接。
问候。
答案 1 :(得分：0)
摘自http://pdfsharp.codeplex.com/releases/view/37054：
如果您喜欢速度：请继续使用PDFsharp 1.30。如果你喜欢小PDF 文件：使用PDFsharp 1.31。 PDFsharp的未来版本将支持 两种模式（赞成速度和青睐大小）。
也许这有帮助。
