PnP Core Component - Check if group exists in SharePoint 2016

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";

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

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

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