将大文件上传到Webservice .net3.5时出现问题 [英] problem uploading large file to a webservice .net3.5
问题描述
尊敬的专家，
我有一个from可以将文件上传到数据表(在会话中)，然后单击send按钮后，它会动态调用Web服务并将文件上传到数据库.
我已将应用程序和Web服务的请求长度等设置为2GB:
< httpRuntime executionTimeout =" maxRequestLength =" / >
一切正常，直到文件大小达到100MB
之后，应用程序向我返回异常:
调用的目标引发了异常.
InnerException:基础连接已关闭:发送时发生意外错误.
我的网络服务代码中有一个自定义例外，因此我知道它永远不会输入网络服务代码.
我应该补充一点，动态调用Web服务是我使用的dll....有人可以帮助我吗?
小错别字和格式[/edit]
[improve]我应该补充说，webservice和Prosentation在同一台服务器上，我也已经通过本地计算机上的UI对此进行了检查，以调用该webservice [/improve]
[improve2]我正在使用.net 3.5 [/improve2]

基于错误消息:"基础连接已关闭:发送中发生意外错误."，由于此处的文件大小，它看起来并不像失败.听起来更像是由于上载的时间之间的连接已关闭.查看是否有这些帮助:
基础连接已关闭... [ ^ ]
解决基础连接已关闭... [
同样，在使用Web服务的客户端应用程序中的此标记.
我已将call webservice方法更改为普通的Web Service调用，并且仍然引发了相同的错误...
Dear Experts,
I have a from that uploads files to data table(in session) and then after clicking on send button it calls a webservice dynamically and uploads the file to data base.
I''ve set the request length and etc for both application and webservice to 2GB:
<httpRuntime executionTimeout="10000" maxRequestLength="2000000"/>
Every thing works fine until the file size reaches to 100MB
After that, the application returns me an exception:
Exception has been thrown by the target of an invocation.
InnerException: The underlying connection was closed: An unexpected error occurred on a send.
I''ve a custom exception on my webservice codes so I know it will never enter the codes of webservice.
I should add that the call web service dynamically is a dll that I used.... can anybody help me?
[edit] little typo and format[/edit]
[improve] I should add that the webservice and the Prosentation are on the same server, also I''ve checked this with UI on my local computer to call that webservice[/improve]
[improve2]I''m using .net 3.5[/improve2]

[/improve]Based on the error message: "The underlying connection was closed: An unexpected error occurred on a send.", it does not looks like a failure because of file size here. It sounds more like the connection got closed in between because of the time it takes to upload. See if these help:
You receive one or more error messages ...[^]
The underlying connection was closed...[^]
Solving "The underlying connection was closed...[^]
<httpruntime executiontimeout="10000" maxrequestlength="2000000" />
Also this tag in client application which is using web service ..
I''ve changed the call webservice method to normal web service calling and still the same error raised...
