从网站删除Sharepoint中的文件

Question

我正在尝试上载文件，以后再从共享点站点中删除文件。 上传效果很好，但删除时出现错误。

这是我的代码：

  private void UploadSharePoint(string siteNumber, string fileName)
    {
        try
        {
            using (ClientContext client = new ClientContext("https://sites.company.com/sites/" + siteNumber + "/"))
            {
                client.Credentials = new NetworkCredential("user", "pw", "domain");
                var formLib = client.Web.Lists.GetByTitle("Documents");
                client.Load(formLib.RootFolder);
                client.ExecuteQuery();

                //File Upload
                var fileCreationInfo = new FileCreationInformation
                {
                    Content = System.IO.File.ReadAllBytes(fileName),
                    Overwrite = true,
                    Url = Path.Combine("Documents/99_Upload", Path.GetFileName(fileName))
                };
                var uploadFile = formLib.RootFolder.Files.Add(fileCreationInfo);
                client.Load(uploadFile);
                client.ExecuteQuery();

                //File Delete
                Web web = client.Web;
                List list = web.Lists.GetByTitle("mydoc");
                client.Load(list);  --> here I get nothing back
                Folder folder = list.RootFolder;
                client.Load(folder);
                FileCollection files = folder.Files;
                client.Load(files);
                client.ExecuteQuery(); 
                Microsoft.SharePoint.Client.File file = files[1];
                file.DeleteObject();
                client.ExecuteQuery(); 
           }
        }
        catch (System.Exception ex)
        {

        }
    }

错误信息：

{“ URL'https ://sites.company.com/sites/333333 '的站点上不存在列表'mydoc'。”}

因此，删除List list = web.Lists.GetByTitle("mydoc");输入内容一定有问题List list = web.Lists.GetByTitle("mydoc");

Sharepoint中显示的标题是mydoc。 文件名是mydoc.txt。 我都尝试了两次，但没有任何效果。

谢谢您的帮助

引发的错误消息是正确的：

{“ URL'https ://sites.company.com/sites/333333 '的站点上不存在列表'mydoc'。”}

问题是您正在创建标题为“ mydoc”的SharePoint列表项 ，但随后您尝试访问标题为“ mydoc”的SharePoint列表 （该列表不存在）。 请参阅下面的更新代码：

            //File Delete
            Web web = client.Web;
            List list = web.Lists.GetByTitle("Documents");
            client.Load(list);  --> here you will get reference to the list

            Microsoft.SharePoint.Client.File file = web.GetFileByServerRelativeUrl("/Documents/mydoc.txt");
            client.Load(file);
            file.DeleteObject();
            client.ExecuteQuery();
