问题

I've 4000+ users in my Office 365 organization and want to add all those users to my SharePoint subsite in C# using CSOM. I know I can achieve this using PowerShell Codes, but I want to do it in C# using CSOM. I can add a particular user by the following code, but how to add all 4000+ users in a single code? Is there any way to iterate an object in a loop which has all 4000+ users in it?

using System;
using System.Security;
using Microsoft.Online.SharePoint.TenantAdministration;
using Microsoft.SharePoint.Client;

namespace Basic_Site_Subsite_Group_User_Creation
{
    class Program
    {
        static void Main(string[] args)
        {
            // Opens the Admin URL
            using (ClientContext ctx = new ClientContext("https://developer19.sharepoint.com/sites/Created_with_Communication_site"))
            {
                // Authenticating with Tenant Admin
                SecureString password = new SecureString();
                foreach (char c in "password".ToCharArray())
                    password.AppendChar(c);
                ctx.Credentials = new SharePointOnlineCredentials("kailash@kailash.cf", password);
                
                Group gru = ctx.Web.SiteGroups.GetByName("subsite1");
                User use = ctx.Web.EnsureUser("anil@kailash.cf");
                gru.Users.AddUser(use);
                ctx.ExecuteQuery();
            }
        }
    }
}

using System;
using System.Security;
using Microsoft.Online.SharePoint.TenantAdministration;
using Microsoft.SharePoint.Client;
namespace Basic_Site_Subsite_Group_User_Creation
{
    class Program
    {
        static void Main(string[] args)
        {
            //Opens the Admin URL 
            using (ClientContext ctx = new ClientContext("https://developer19.sharepoint.com/sites/Created_with_Communication_site"))
            {
                //Authenticating with Tenant Admin
                SecureString password = new SecureString();
                foreach (char c in "password".ToCharArray())
                    password.AppendChar(c);
                ctx.Credentials = new SharePointOnlineCredentials("kailash@kailash.cf", password);
                    Group gru = ctx.Web.SiteGroups.GetByName("subsite1");
                    User use = ctx.Web.EnsureUser("anil@kailash.cf");
                    gru.Users.AddUser(use);
                    ctx.ExecuteQuery();

你可以在你的组织中使用这个代码（我相信是这样的）

string groupName = "Domain Users";
string domainName = "你的域名";
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, domainName);
GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.SamAccountName, groupName);
if (grp != null)
{
    foreach (Principal p in grp.GetMembers(false))
    {
        p.DisplayName //在这里执行你的操作
    }

    grp.Dispose();
    ctx.Dispose();
}

请注意，这段代码用于操作活动目录（Active Directory）。

string groupName = "Domain Users";
string domainName = "your domainName";
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, domainName);
GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.SamAccountName, groupName);
if (grp != null)
{
     foreach (Principal p in grp.GetMembers(false))
        {
            p.DisplayName //do your action here
        }


    grp.Dispose();
    ctx.Dispose();
}

请参考此项目以注册您的应用程序，以便您可以调用 Graph API 以获取来自 AD 的用户。

if (graphServiceClient != null)
{
    var users = await graphServiceClient.Users.Request().GetAsync();
}

在将用户添加到 SharePoint 时，建议使用批处理方式（每次提交 100 个用户以避免问题）。

伪代码示例：

for (var i = 1; i <= users.Count; i++)
{
    User user = ctx.Web.EnsureUser(users[i].Mail);
    gru.Users.AddUser(user);
    if (i % 100 == 0)
    {
        ctx.ExecuteQuery();
    }
}

Refer [this project][1] to register your app so you could call graph api to get users from AD.

    if (graphServiceClient != null)
                    {
                        var users= await graphServiceClient.Users.Request().GetAsync();

When adding the users to SharePoint, would suggest do this batch(submit 100 users in one request to avoid issue).

Fake code:

    for(var i = 1; i &lt;= users.Count; i++)
                        {
                            User use = ctx.Web.EnsureUser(users[i].Mail);
                            gru.Users.AddUser(use);
                            if (i % 100 == 0)
                            {
                                ctx.ExecuteQuery();
                            }
                        }
