上传大文件100mb+；通过c#Web服务访问Sharepoint 2010

我无法将大型文件上载到Sharepoint 2010。我正在使用Visual Studio 2010和C语言。我从网上找到的内容中尝试了多种方法，但没有任何效果。我已将设置和配置文件更改为允许的最大上载限制，但仍然没有更改。我将copy.asmx用于小文件，它工作正常，当文件太大并引发异常时，我尝试上载DataAsync，但这不起作用。请看下面的代码

非常感谢您的任何/所有帮助

为了使其正常工作，您必须更改SharePoint配置以增加上载限制和超时。下面的链接显示了使大型文件上传正常工作的必要步骤

谢谢毗瑟奴，我已经这么做了，但是没有用。我找到了另一种使用UploadData和UploadDataAsync的方法，如下所示，这似乎很有效。
