我用流的方式上传文件，文件大小在几M的时候上传没问题，但是如果文件大小超过一定量就报404错误，我的web.config如下：
<system.serviceModel>

客户端是winform，app.config如下：
<system.serviceModel>
<bindings>
<basicHttpBinding>

openTimeout="00:03:00" receiveTimeout="00:30:00" sendTimeout="00:03:00" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="9223372036854775807"

</binding>

<client>
<endpoint address="http://localhost:27324/DataService.svc" binding="basicHttpBinding"

按照网上的文章该设置的都设置了~ 可是只要文件一大，直接没调用wcf里的uploadfile，直接报404错误
------解决思路----------------------
大文件本来就不适合
用ftp把
------解决思路----------------------
直接这么上传肯定内存爆。
用第三方的上传控件，人家 是分块分块的上传，这样还能显示进度呢。
