我已经使用asp.net MVC实现了一个Web应用程序,将excel文件转换为.csv文件。
小文件一切正常。
但是当我试图运行更大的文件时,我在客户端收到错误“ERR_CONNECTION_RESET”。
我做过R& D并找到了解决方案,即
即便如此,我也面临同样的问题。然后我通过引用Set Timeout For Controller Action实现了线程。
现在我得到了“线程被中止”的例外。
这里我添加了堆栈跟踪。请帮我解决一下......

FileUpload fileUpload = new FileUpload();
try

string filename = Path.GetFileName(model.SourceFile);
model.SourceFile = Path.Combine(Server.MapPath("~/App_Data/uploads"), filename);
model.WorkSheet1 = "Upload file$";
System.Threading.Tasks.Task.Factory.StartNew(() => ConvertExcelToCSV_LT(model));
fileUpload.SourceFile = filename;
}
catch (Exception e)

return Json(new { filemodel = fileUpload }, JsonRequestBehavior.AllowGet);

你试过玩
吗?<httpRuntime executionTimeout="HH:MM:SS" />
默认情况下,您的播放时间限制为110秒。

在web.config中增加上传大小
<system.web>
<httpRuntime maxRequestLength="2147483647" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="52428800" /> <!--50MB-->
</requestFiltering>
</security>
</system.webServer>
maxRequestLength
是Int32
(check here),因此您可以相应地设置尺寸。
maxAllowedContentLength
是uint
(check here)

您是否使用TaskCreationOptions.LongRunning
尝试了?
Task.Factory.StartNew(() => ConvertExcelToCSV_LT(model),
TaskCreationOptions.LongRunning);
