这里是我的web.config

    <services> 
     <service behaviorConfiguration="RestBehavior" name="EyePlots.Videos">

    <behaviors> 
     <endpointBehaviors>

     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    </system.serviceModel> 
</configuration>

它可能是系统的可扩展性问题吗？如果你们想要，我可以发布我的代码片段吗？谢谢！

我觉得4兆是IIS节流。

是否已经设置（IIS7 +）

<system.webServer> 
    <security> 
    <requestFiltering> 
     <requestLimits maxAllowedContentLength="2147483648" /> 
    </requestFiltering> 
    </security> 
</system.webServer>

添加一个链接列出了允许答复者上传大文件的更多限制。 –
