通过c#Web服务将100mb +的大文件上传到Sharepoint 2010 [英] Upload large files 100mb+ to Sharepoint 2010 via c# Web Service

问题描述

我无法将大文件上传到Sharepoint2010.我正在使用Visual Studio 2010和Language C#.我从网上找到的内容尝试了多种方法，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，但还是一无所获.我正在将copy.asmx用于运行良好的小文件，并在文件太大且引发异常时尝试使用UploadDataAsync，但此方法不起作用.请看下面的代码...

I am unable to upload large files to Sharepoint 2010. I am using Visual Studio 2010 and Language C#. I have tried multiple ways from content I have found online but nothing has worked. I have changed the settings and config files to the maximum allowed upload limits and still nothing. I am using the copy.asmx for small files which works fine and am trying UploadDataAsync when the file is too large and an exception is thrown but this is not working. Please take a look at the code below...

非常感谢您提供任何帮助.
