我可以使用以下C＃代码从TFS检索用户列表。但是，我想更改并保留用户的显示名称。这是我的代码。

using System;
using System.Collections.Generic;
using microsoft.TeamFoundation.Client;
using microsoft.TeamFoundation.Framework.Client;
using microsoft.TeamFoundation.Framework.Common;

namespace ConsoleApplication3
{
  class Program
  {
    static void Main(string[] args)
    {

        TfsConfigurationServer tcs = new TfsConfigurationServer(new Uri("http://tfsserver:8080/tfs"));

        IIdentityManagementService ims = tcs.GetService<IIdentityManagementService>();

        TeamFoundationIdentity tfi = ims.ReadIdentity(IdentitySearchFactor.accountName,"[TEAM FOUNDATION]\\Team Foundation Valid Users",MembershipQuery.Expanded,ReadIdentityOptions.None);

        TeamFoundationIdentity[] ids = ims.ReadIdentities(tfi.Members,MembershipQuery.None,ReadIdentityOptions.None);

        foreach (TeamFoundationIdentity id in ids)
        {
            if (id.Descriptor.IdentityType == "system.security.Principal.WindowsIdentity")
            {
                var displayName = id.DisplayName;

                // Now I would like to change this displayName and persist the change ??? 
            }
        }

        Console.ReadLine();
    }
  }
}
