尝试 运行 提供商托管的应用程序到 SharePoint online 时出错

Question

最近我正在尝试创建一个提供商托管的应用程序来在线共享积分。 我已经配置了 Azure Web 应用程序并创建了应用程序并将其发布到在线共享点。我现在可以在 SharePoint 在线应用程序目录中看到该应用程序。但是当我尝试 运行 应用程序时，它抛出以下错误。

System.IO.FileNotFoundException: msoidcliL.dll at Microsoft.SharePoint.Client.Idcrl.IdcrlNativeMethodsSelector..ctor(String dllPath) at Microsoft.SharePoint.Client.Idcrl.ManagedIdcrl.get_IdcrlNativeMethods() at Microsoft.SharePoint.Client.Idcrl.ManagedIdcrl.EnsureInited() at Microsoft.SharePoint.Client.Idcrl.ManagedIdcrl.LogonIdentity(String username, SecureString password) at Microsoft.SharePoint.Client.Idcrl.SharePointOnlineAuthenticationProvider.Logon(String username, SecureString password) at Microsoft.SharePoint.Client.SharePointOnlineCredentials..ctor(String username, SecureString password) at SharePointApp5Web.Default.Page_Load(Object sender, EventArgs e) 

代码

 var spContext = SharePointContextProvider.Current.GetSharePointContext(Context);

        try
        {
            string str;
            using (ClientContext ctx = new ClientContext("https://mydomain.sharepoint.com/sites/General/Community%20Portal/HR/Acknowledgements"))
            {
                ctx.Credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials("myname@domain.com", ConvertToSecureString("password"));

                Web myweb = ctx.Web;
                List myList = myweb.Lists.GetByTitle("Timesheet Administration Policy");
                ListItemCreationInformation ItemCreationInfo = new ListItemCreationInformation();

                CamlQuery camlQuery = new CamlQuery();
                camlQuery.ViewXml =
                    @"<Query>
                   <Where>
                      <Neq>
                         <FieldRef Name='ID' />
                         <Value Type='Counter'>946</Value>
                      </Neq>
                   </Where>
                </Query>";


                Microsoft.SharePoint.Client.ListItemCollection listItems = myList.GetItems(camlQuery);
                ctx.Load(listItems);
                ctx.ExecuteQuery();


                    foreach (Microsoft.SharePoint.Client.ListItem listItem in listItems.ToList())
                    {

                        try
                        {
                            Response.Write(listItem["Email_x0020_Address"].ToString().Trim());

                        }
                        catch (Exception ex)
                        {
                            Response.Write(ex.ToString());
                        }
                    }
                }
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());
        }

CSOM dll 似乎有问题。请安装最新的 CSOM 在线版本，然后 deploy/publish 您的代码。

转到Visual studio中的项目引用，右键打开Manage Nuget packages如下：

搜索 CSOM 并安装 Microsoft.SharePointOnline.CSOM

或者，您也可以从下面提到的 Microsoft 下载 link 下载它并手动添加引用：

SharePoint Online Client Components SDK

此外，确保 .NET 框架面向 v4.5 并且平台目标设置为 Any CPU。另外，确保引用了 v16 程序集。

此外，在 ctx.Credentials 行下方添加以下代码：

ctx.AuthenticationMode = ClientAuthenticationMode.Default;
