在ASP.net中保存PDF文件后，应用程序结束 [英] Application End after saving PDF file in ASP.net

问题描述

我创建了一个函数，该函数从会话中获取HTML数据并将其另存为PDF
为此，我使用了 NReco.PdfGenerator

I created one function which get HTML data from session and save that as PDF
for that I used NReco.PdfGenerator

private static string savePdf()
{
    if (HttpContext.Current.Session["ReservationPrintHtml"] != null)
    {
        StringBuilder objStringBuilder = ((StringBuilder)HttpContext.Current.Session["ReservationPrintHtml"]);
        string dir = HostingEnvironment.MapPath("~/Pdf");
        if (!Directory.Exists(dir))
        {
            Directory.CreateDirectory(dir);
        }
        string fileName = "PDF-" + DateTime.Now.ToString("yyyyMMdd-HHMMssffffff") + ".pdf";
        string downloadFile = Path.Combine(dir, fileName);
        string htmlContent = objStringBuilder.ToString();
        byte[] pdfBytes = (new NReco.PdfGenerator.HtmlToPdfConverter()).GeneratePdf(htmlContent);
        File.WriteAllBytes(downloadFile, pdfBytes);
        return fileName;
    }
    else
    {
        return null;
    }
}

我没有遇到有关PDF生成的任何问题，但是，执行此函数后，它直接在 Global.asax
中调用 Application_End 我已经尝试过在应用程序中遇到任何错误，但 Application_Error 无法执行.

I'm not facing any issue regarding PDF generation but, After this function execution it directly calls Application_End in Global.asax
I have tried if I get any error in application but Application_Error not execute.

谁能知道这是什么问题?
谢谢.

Can anyone have idea what is the problem?
Thank you.

推荐答案

经过长时间的搜索和搜索，我发现我将文件保存在项目中包含的 PDF 文件夹中.
因此，每生成一个新的PDF文件时，文件夹更改中的每个 15-20 更改之后，文件夹更改中的 AppDomain recycle 都会运行，这些文件包含在解决方案所包含的项目中.因此我通过在 web.cofig 文件中添加 fcnMode ="Disabled" 来找到解决方案，如下所示.

After long search and googling I found that I'm saving files in PDF folder which was included in my project.
So whenever new PDF file was generated AppDomain recycle on folder change run after every 15-20 changes in folders which are included in solution included projects. so I found solution by adding fcnMode="Disabled" in web.cofig file like below.

<httpRuntime targetFramework="4.5.2" fcnMode="Disabled" />
