Error:"The user doesn't exist or is not unique" in sharepoint Adding user using CSOM

Question

我正在尝试使用 CSOM 将用户添加到 SharePoint 网站，但我收到一条说明 'The user does not exist or is not unique' 我的登录名有问题吗？。 "anil@developer19.onmicrosoft.com" 是组织中的活跃用户。

using System;
using System.Security;
using Microsoft.Online.SharePoint.TenantAdministration;
using Microsoft.SharePoint.Client;
namespace CreateSiteCollections
{
    class Program
    {
        static void Main(string[] args)
        {
           //Opens the Admin URL 
            using (ClientContext ctx1 = new ClientContext("https://developer19.sharepoint.com/sites/codesite"))
            {
                //Authenticating with Tenant Admin
                SecureString passWord = new SecureString();
                foreach (char c in "Password".ToCharArray())
                    passWord.AppendChar(c);
                ctx1.Credentials = new SharePointOnlineCredentials("kailash@developer19.onmicrosoft.com", passWord);
                        GroupCollection cg = ctx1.Web.SiteGroups;
                        Group oGroup = cg.GetById(14);

                        UserCreationInformation user = new UserCreationInformation();
                        user.Email = "anil@developer19.onmicrosoft.com";
                        user.LoginName = "developer19/anil";
                        user.Title = "Anil";
                        User oUser = oGroup.Users.Add(user);
                        ctx1.ExecuteQuery();
            }
      }
   }
}

Answer 1

我在 http://www.codesharepoint.com/csom/add-user-to-site-group-in-sharepoint-using-csom 上学会了其他方法，而不是尝试这些整个步骤。但是您可以同时使用 GetByName 或 GetById。

Group oGroup = ctx.Web.SiteGroups.GetByName("NewCSOM Group");
                User oUser = ctx.Web.EnsureUser("anil@developer19.onmicrosoft.com");
                oGroup.Users.AddUser(oUser);
                ctx.ExecuteQuery();

Answer 2

用户的登录名可以用Rest检查API:

siteurl/_api/web/siteusers

因此对于 UserCreationInformation class，更新有效的登录名将起作用：
