I have a custom list named Custom in the SharePoint 2013 site. Custom list has the following columns.

Ø Title – Single line of text

Ø Metadata – Managed Metadata (Allow Multiple Values is enabled)

I have added an item which has the following value

Ø Title – Test

Ø Metadata – Term1;Term2;

In this blog you will see how to get the Metadata column values for the item from Custom list using Client Side Object Model in SharePoint 2013.

3. Select Console Application in the Visual C# node from the installed templates.

4. Enter the Name and click on Ok.

5. In the solution explorer, right click on References folder and then click on Add Reference.

6. Add the following assemblies from 15 hive (C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\ISAPI).

a. Microsoft.SharePoint.Client.dll

b. Microsoft.SharePoint.Client.Runtime.dll

c. Microsoft.SharePoint.Client.Taxonomy.dll

7. Open Program.cs file and replace the code with the following

 
 
using System;
using System.Collections.Generic;
using System.Linq;

using System.Collections.ObjectModel;
 
namespace ManagedMetadataClient
{
    class Program
    {
        static void Main(string[] args)
        {
            // ClienContext - Get the context for the SharePoint Site 
            // SharePoint site URL - http://c4968397007/
            ClientContext clientContext = new ClientContext("http://c4968397007/");
 
            // SharePoint web
            Web web = clientContext.Web;
 
            // Get the list using Title
            List list = web.Lists.GetByTitle("Custom");
 
            // Get the list item by id
            ListItem item = list.GetItemById(2);
            clientContext.Load(item);
 
            // Execute the query to the server
            clientContext.ExecuteQuery();
 
            // Taxonomy field value
            TaxonomyFieldValueCollection taxFieldValueColl = item["Metadata"] as TaxonomyFieldValueCollection;
 
            // Loop through all the taxonomy field values
            foreach (TaxonomyFieldValue taxFieldValue in taxFieldValueColl)
            {
                // Display the taxonomy field value
                Console.WriteLine(taxFieldValue.Label);
            }
            Console.ReadLine();                
        }
    }}
