Question

我正在尝试使用c＃将视频上传到SharePoint 2013文档库，每次代码运行时，我都会收到“找不到文件”异常，它只会对.mp4文件引发错误。如果我为此上传jpg或任何其他文件格式，它将可以使用。我究竟做错了什么？预先感谢您的帮助。

        string result = string.Empty;

        try
        {
            //site url
            ClientContext context = new ClientContext("siturl");

            // The SharePoint web at the URL.
            Web web = context.Web;

            FileCreationInformation newFile = new FileCreationInformation();
            newFile.Content = System.IO.File.ReadAllBytes(@"C:\test.mp4");
            newFile.Url = "test.mp4";

            List docs = web.Lists.GetByTitle("Learning Materials2");

            Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
            context.Load(uploadFile);
            context.ExecuteQuery();
        }catch(Exception Ex)
        {

        }

更新创建了一个供人们下载的库，该库可用于上传.mp4 https://github.com/bikecrazyy/sharepoint-library-uploader

Answer 1

string fileName=@"C:\test.mp4";
using (var clientContext = new ClientContext(siturl))
{
     using (var fs = new FileStream(fileName, FileMode.Open))
     {
         var fi = new FileInfo(fileName);
         var list = clientContext.Web.Lists.GetByTitle("Learning Materials2");
         clientContext.Load(list.RootFolder);
         clientContext.ExecuteQuery();
         var fileUrl = String.Format("{0}/{1}", list.RootFolder.ServerRelativeUrl, fi.Name);
     Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, fileUrl, fs, true);
 }

Answer 2

我对SharePoint没有特定的了解。但是对于网站和IIS，如果扩展名未在MIME Types下列出，则浏览器将抛出404。

SharePoint似乎有类似的东西。参见

和

Answer 3

您是否尝试过从SharePoint UI将文件上传到SharePoint文档库？它运作良好吗？可能是SharePoint网站可以配置为禁止某些文件类型。

此外，是否希望使用CSOM模型检索上传到SharePoint的文件？
