PnP Core Component - Check if list exists in SharePoint 2016

Posted By:Vijai Anand. R       Posted Date: May 16, 2016    Points: 200    Category: SharePoint    URL: http://www.dotnetspark.com  

In this article you will see how to check if list exists in SharePoint 2016 with CSOM Extension Method using Console Application.
 

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

Syntax:

ListExists(Microsoft.SharePoint.Client.Web,System.String)

Description: Checks if list exists on the particular site based on the list Title property.

Parameters:

web: Site to be processed - can be root web or sub site

listTitle: Title of the list to be checked.

Code Snippet:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
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://c7395723754:35298/sites/VijaiDemo";
            string userName = "administrator";
            string password = "Xxxxxxxxx";
            string domain = "AD2012";
            string listName = "PnP Custom List";

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

            try
            {
                // Get the client context
                using (var ctx = authMgr.GetNetworkCredentialAuthenticatedContext(siteUrl, userName, password, domain))
                {
                    // Check if list exists using CSOM Extension Method
                    if (ctx.Web.ListExists(listName))
                    {
                        Console.WriteLine(listName + " exists");
                    }
                    else
                    {
                        Console.WriteLine(listName + " does not exists.");
                    }
                }
            }

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