Question

如果有可能，我想帮助我完成这项任务。我希望能够将文件上传到Sharepoint Online上的文件夹。目前，我只能上传到图书馆。以下是我目前使用的代码。

private void BtnUpload_Click(object sender, EventArgs e)
{
    siteURL += "/" + tbDept.Text;

    try
    {
        using (ClientContext ctx = new ClientContext(siteURL))
        {
            SecureString passWord = new SecureString();
            foreach (var c in logUser.getPassword())
            {
                passWord.AppendChar(c);
            }
            ctx.Credentials = new SharePointOnlineCredentials(logUser.getUsername(), passWord);
            Web web = ctx.Web;

            foreach (string fname in arrAllFiles)   //arrAllFiles --> contains multiple files to be uploaded
            {
                FileCreationInformation newFile = new FileCreationInformation();
                newFile.Overwrite = true;
                newFile.Content = System.IO.File.ReadAllBytes(fname);
                newFile.Url = System.IO.Path.GetFileName(fname);
                List docs = web.Lists.GetByTitle(tbLibrary.Text); //tbLibrary --> Library's Name
                Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
                ctx.ExecuteQuery();
            }
            MessageBox.Show("Upload Complete!");
            siteURL = "https://mycompany.sharepoint.com";
        }
    }
    catch(Exception ex)
    {
        MessageBox.Show(ex.Message);
        siteURL = "https://mycompany.sharepoint.com";
    }
}

代码运行正常。我只需要添加功能，以便将文件上传到库中的特定文件夹。

提前谢谢。

这是我之前写过的一些示例代码。您可以根据自己的需要进行调整。 SaveBinaryDirect方法获取上下文和包含该文件夹的相对路径。这应该有用。

ClientContext ctx = new ClientContext("http://sp13");

Folder folder = ctx.Web.GetFolderByServerRelativeUrl("Shared Documents");
string file = String.Concat(Environment.CurrentDirectory, @"\Files\SharePointGuidance2010.pdf");

List docLib = ctx.Web.Lists.GetByTitle("Documents");
ctx.Load(docLib);
ctx.ExecuteQuery();

using (MemoryStream stream = new MemoryStream( System.IO.File.ReadAllBytes(file) ) )
{
Microsoft.SharePoint.Client.File.SaveBinaryDirect(ctx, "/shared documents/SubFolder/spg.pdf", stream, true);
}

或对您的代码进行以下编辑：

Folder folder = web.GetFolderByServerRelativeUrl("Documents/Subfolder");
FileCreationInformation fci = new FileCreationInformation();
fci.Content = System.IO.File.ReadAllBytes(@”..\..\myfile.txt”);
fci.Url = “myfile.txt”;
fci.Overwrite = true;
File fileToUpload = folder.Files.Add(fci);
ctx.Load(fileToUpload);

ctx.ExecuteQuery();

<强>更新下面的代码工作，我自己测试了它：

var filePath = @"C:\PATH_TO_FILE\test.docx";

using (var context = new ClientContext("YOUR_SITE_URL") { Credentials = credentials })
{
    var folder = context.Web.GetFolderByServerRelativeUrl("/sites/YOUR_SITE/LIBRARY_INTERNAL_NAME/FOLDER_NAME");

    context.Load(folder);
    context.ExecuteQuery();

    folder.Files.Add(new FileCreationInformation
    {
        Overwrite = true,
        Content = System.IO.File.ReadAllBytes(filePath),
        Url = Path.GetFileName(filePath)
    });

    context.ExecuteQuery();
}
