在Filepoint Online中使用文件管理器

Question

我正在嘗試連接到SharePoint Online，以瀏覽SharePoint上的文件夾，並使圖像文件導入到sql表中。 無法通過文件管理器訪問它-路徑顯示為無效（如果我通過SharePoint瀏覽並輸入u / p-路徑可訪問且有效）

我已經設置了一個代碼，要求輸入用戶密碼（我自動獲得的用戶名），它似乎可以在線連接到SharePoint，但是當我在瀏覽器中鍵入路徑時-出現無效的路徑錯誤。

調用此代碼以傳遞u / p（在幕后）：

 protected void ConnectShrpt_Click(object sender, EventArgs e) { String DocLibName = "Documents"; If ((HiddenPassw.Value != "") && (HiddenUserEmail.Value !="")) { ClientContext clientContext = new ClientContext(FolderImage); SharePointOnlineCredentials cred = new SharePointOnlineCredentials(HiddenUserEmail.Value, ConvertToSecureString(HiddenPassw.Value)); clientContext.Credentials = cred; List list = clientContext.Web.Lists.GetByTitle(DocLibName); clientContext.Load(list.RootFolder); clientContext.ExecuteQuery(); } }​ 

我沒有收到以上代碼的任何錯誤消息。 一旦我進入瀏覽器-使用asp：FileUpload-那就是當我得到錯誤消息，指出路徑不存在。 如果我在相同的瀏覽器中手動進入相同的位置並輸入u / p，則可以使用相同的FileUpload瀏覽到該位置。 我需要我的代碼才能自動連接到SharePoint Online。 PS FolderImage是SharePoint網站的URL。

更新！ 雖然在開發人員環境中沒有錯誤，但是一旦將其部署到SharePoint Server IIS時，我在上面附帶的代碼中就會出現錯誤。

檢查“ FolderImage ”變量的數據。

要傳遞ClientContext方法，您需要傳遞站點URL。

string webUrl = "https://tenant-name.sharepoint.com/sites/test/";
ClientContext clientContext  = new ClientContext(webUrl)
