如何将文件上传到 sharepoint 中的文档库？

Question

如何以编程方式将文件上传到 sharepoint 中的文档库？

我目前正在使用 C# 制作一个 Windows 应用程序，它会将文档添加到文档库列表中。

Answer 1

您可以使用对象模型或SharePoint Webservices 将文档上传到 SharePoint 库。

使用对象模型上传：

String fileToUpload = @"C:\YourFile.txt";
String sharePointSite = "http://yoursite.com/sites/Research/";
String documentLibraryName = "Shared Documents";

using (SPSite oSite = new SPSite(sharePointSite))
{
    using (SPWeb oWeb = oSite.OpenWeb())
    {
        if (!System.IO.File.Exists(fileToUpload))
            throw new FileNotFoundException("File not found.", fileToUpload);                    

        SPFolder myLibrary = oWeb.Folders[documentLibraryName];

        // Prepare to upload
        Boolean replaceExistingFiles = true;
        String fileName = System.IO.Path.GetFileName(fileToUpload);
        FileStream fileStream = File.OpenRead(fileToUpload);

        // Upload document
        SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);

        // Commit 
        myLibrary.Update();
    }
}

如果您在此行中收到此错误“值不在预期范围内”：

SPFolder myLibrary = oWeb.Folders[documentLibraryName];

改用这个来修复错误：

SPFolder myLibrary = oWeb.GetList(URL OR NAME).RootFolder;

总是使用 URl 来获取列表或其他，因为它们是唯一的，名称不是最好的方法；）

使用 SharePoint 2013 新库，我设法做到了这样的事情：

private void UploadToSharePoint(string p, out string newUrl)  //p is path to file to load
{
    string siteUrl = "https://myCompany.sharepoint.com/site/";
    //Insert Credentials
    ClientContext context = new ClientContext(siteUrl);

    SecureString passWord = new SecureString();
    foreach (var c in "mypassword") passWord.AppendChar(c);
    context.Credentials = new SharePointOnlineCredentials("myUserName", passWord);
    Web site = context.Web;

    //Get the required RootFolder
    string barRootFolderRelativeUrl = "Shared Documents/foo/bar";
    Folder barFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl);

    //Create new subFolder to load files into
    string newFolderName = baseName + DateTime.Now.ToString("yyyyMMddHHmm");
    barFolder.Folders.Add(newFolderName);
    barFolder.Update();

    //Add file to new Folder
    Folder currentRunFolder = site.GetFolderByServerRelativeUrl(barRootFolderRelativeUrl + "/" + newFolderName);
    FileCreationInformation newFile = new FileCreationInformation { Content = System.IO.File.ReadAllBytes(@p), Url = Path.GetFileName(@p), Overwrite = true };
    currentRunFolder.Files.Add(newFile);
    currentRunFolder.Update();

    context.ExecuteQuery();

    //Return the URL of the new uploaded file
    newUrl = siteUrl + barRootFolderRelativeUrl + "/" + newFolderName + "/" + Path.GetFileName(@p);
}

string filePath = @"C:\styles\MyStyles.css"; 
string siteURL = "http://example.org/"; 
string libraryName = "Style Library"; 

using (SPSite oSite = new SPSite(siteURL)) 
{ 
    using (SPWeb oWeb = oSite.OpenWeb()) 
    { 
        if (!System.IO.File.Exists(filePath)) 
            throw new FileNotFoundException("File not found.", filePath);                     

        SPFolder libFolder = oWeb.Folders[libraryName]; 

        // Prepare to upload 
        string fileName = System.IO.Path.GetFileName(filePath); 
        FileStream fileStream = File.OpenRead(filePath); 

        //Check the existing File out if the Library Requires CheckOut
        if (libFolder.RequiresCheckout)
        {
            try {
                SPFile fileOld = libFolder.Files[fileName];
                fileOld.CheckOut();
            } catch {}
        }

        // Upload document 
        SPFile spfile = libFolder.Files.Add(fileName, fileStream, true); 

        // Commit  
        myLibrary.Update(); 

        //Check the File in and Publish a Major Version
        if (libFolder.RequiresCheckout)
        {
                spFile.CheckIn("Upload Comment", SPCheckinType.MajorCheckIn);
                spFile.Publish("Publish Comment");
        }
    } 
}

作为 Web 服务的替代方案，您可以使用来自 FrontPage RPC API 的 put document 调用。这具有使您能够在与文件数据相同的请求中提供元数据（列）的额外好处。明显的缺点是该协议有点晦涩（与有据可查的 Web 服务相比）。

有关说明 Frontpage RPC 使用的参考应用程序，请参阅 CodePlex 上的 SharePad 项目。

try
{
    //Variablen für die Verarbeitung
    string source_file = @"C:\temp\offer.pdf";
    string web_url = "https://stackoverflow.sharepoint.com";
    string library_name = "Documents";
    string admin_name = "admin@stackoverflow.com";
    string admin_password = "Password";

    //Verbindung mit den Login-Daten herstellen
    var sercured_password = new SecureString();
    foreach (var c in admin_password) sercured_password.AppendChar(c);
    SharePointOnlineCredentials credent = new 
    SharePointOnlineCredentials(admin_name, sercured_password);

    //Context mit Credentials erstellen
    ClientContext context = new ClientContext(web_url);
    context.Credentials = credent;

    //Bibliothek festlegen
    var library = context.Web.Lists.GetByTitle(library_name);

    //Ausgewählte Datei laden
    FileStream fs = System.IO.File.OpenRead(source_file);

    //Dateinamen aus Pfad ermitteln
    string source_filename = Path.GetFileName(source_file);

    //Datei ins SharePoint-Verzeichnis hochladen
    FileCreationInformation fci = new FileCreationInformation();
    fci.Overwrite = true;
    fci.ContentStream = fs;
    fci.Url = source_filename;
    var file_upload = library.RootFolder.Files.Add(fci);

    //Ausführen
    context.Load(file_upload);
    context.ExecuteQuery();
    
    //Datenübertragen schließen
    fs.Close();
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message, "Fehler");
    throw;
}

我使用这篇文章允许 c# 访问一个共享点站点。

http://www.thesharepointguide.com/access-office-365-using-a-console-application/

基本上，您创建一个 ClientId 和 ClientSecret 密钥以使用 c# 访问该站点

希望对你有帮助！
