通过 c# Web 服务将 100mb+ 的大文件上传到 Sharepoint 2010

Question

我无法将大文件上传到 Sharepoint 2010。我使用的是 Visual Studio 2010 和语言 C#。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传限制，但仍然没有。我正在将 copy.asmx 用于工作正常的小文件，并且当文件太大并且抛出异常但它不起作用时正在尝试 UploadDataAsync。请看下面的代码...

非常感谢任何/所有帮助。

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