因此，此应用程序在Visual Studio中无缝运行，但我为遇到错误的程序创建了一个安装程序。我想我已经确定了问题所在。当收到一个POST时，它会处理一个单独的分离进程，最终会从网页处理/关闭中取消。处理POST后线程中止
程序流程是这样
- POST接收
context.Request.HttpMethod == "POST"， - 相关XML信息提取并写入磁盘，
csfireEyeHandler.DonJobOnLastIp()，- 在后台运行的监视器上的文件拾取创建事件`void OnChanged'并开始基于XML文档运行服务
FileAdded- >readerRef.ReadInServices(e.FullPath, false)。
问题是POST处理后，它导致服务中止与ThreadAbortException。如果在服务完成后handler.ProcessRequest(context)之后放置了延迟，我推测因为该页面仍然打开。我无法弄清楚如何正确处理这种情况，它非常难以调试，因为我无法在VS中发生错误。
public partial class fireEye : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
HttpContext context = Context;
fireEyeHandler handler = new fireEyeHandler();
handler.ProcessRequest(context);
}
}
public class fireEyeHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
if (context.Request.HttpMethod == "POST")
{
var extension = context.Request.Url.AbsolutePath.Split('/')[2].ToLower();
var stream = context.Request.InputStream;
var buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
var xml = Encoding.UTF8.GetString(buffer);
FileManage.WriteToFile(xml, @"C:\ECC_output\fireEye.xml");
var csfireEyeHandler = new FireEyeService { config = extension + ".config" };
csfireEyeHandler.Load();
csfireEyeHandler.DonJobOnLastIp();
context.Response.StatusCode = 202;
}
}

Web应用程序对监视器一无所知。监视器从正在放入目录的xml文件启动服务。我认为，既然他们没有提到对方，也不能让另一方终止，但事实并非如此。我将尝试将FireEye处理程序移到MVC控制器，以便它不在处理的网页中。 – flaVius 2012-07-19 21:50:23
我不认为移动它会让你受益良多。我相信你在这里有一个基本的设计问题。你有一些忙于尝试读取文件的背景中，而另一些忙于尝试读取或写入这些相同的文件。要么你必须让你的文件观察器处理程序退后一步，让其他代码完成，或者通过某种方式发送创建已发生且所有写入已完成的代码。 – 2012-07-20 00:30:00
我真的不认为文件系统监视器是正确的解决方案;您可以在创建通知后添加暂停;但无论你选择什么时候暂停，总会是错误的。这一切都在同一个过程中，为什么不只是创建通知代码的代码来记录或执行报告。 – 2012-07-20 00:30:53
