试试

k，已经发现httpRunTime默认为最大4000 kb ...
< configuration>
< system.web>
< httpRuntime maxRequestLength =" 4000"
useFullyQualifiedRedirectUrl =" true"
executionTimeout =" 45"
versionHeader =" 1.1.4128" />
< /system.web>
< / configuration>
如何更改？
谢谢。

你，呃......改变它。你试过的时候发生了什么？
You, uhh... change it. What happened when you tried?
我可以上传最大大小为4000 kB的文件。
这就是$.
我尝试添加< httpRuntime>我的项目的Web.config中的节点，但是
不起作用（猜测machine.config比
应用程序级别有更大的权限吗？）。 />
所以我看到的唯一解决方案是更改machine.config文件？
这是正确的吗？

I can upload files of a maximum size of 4000 kB.
That''s the default maximum size specified in Machine.config.
I tried to add the <httpRuntime> node in the Web.config of my project, but
that doesn''t work (guess machine.config has greater permission than on
application level ?).
So the only solution I see is changing the machine.config file ?
Is that correct ?
