PnP Core Component - Check if user exists in the group in SharePoint 2016

In this blog you will see how to check if user exists in the group in SharePoint 2016 with CSOM Extension Method using Console Application.

Please refer to the Introduction to PnP Core Component and OfficeDevPnP.Core for more details. I have created a console application and added SharePointPnPCore2016 NuGet package for the SharePoint 2016 version.

 

Code Snippet: 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.SharePoint.Client;
using OfficeDevPnP.Core;

namespace SP2016PnPCoreComponentDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            // Input Parameters
            string siteUrl = "http://c7395723754/";
            string userName = "administrator";
            string password = "Mf165Nz2WV";
            string domain = "AD2012";
            string groupName = "Group created using PnP";
            string userLoginName = @"ad2012\administrator";

            OfficeDevPnP.Core.AuthenticationManager authMgr = new OfficeDevPnP.Core.AuthenticationManager();

            try
            {
                // Get the client context
                using (var ctx = authMgr.GetNetworkCredentialAuthenticatedContext(siteUrl, userName, password, domain))
                {
                    // Check if user exists in the group
                    if (ctx.Web.IsUserInGroup(groupName,userLoginName))
                    {
                        Console.WriteLine(userLoginName + " exists in the group: "+ groupName);
                        Console.ReadLine();
                    }
                }
            }

            catch (Exception ex)
            {
                Console.WriteLine("Error Message: " + ex.Message);
            }
        }
    }
}
