Locking WebClient - multithreaded application

I have webClient that I am using in my bot:

using System;
using System.Net;

namespace Game_Bot
{
    class WebClientEx : WebClient
    {
        public CookieContainer CookieContainer { get; private set; }

        public WebClientEx()
        {
            CookieContainer = new CookieContainer();
        }

        public void ClearCookies()
        {
            CookieContainer = new CookieContainer();
        }

        protected override WebRequest GetWebRequest(Uri address)
        {

            var request = base.GetWebRequest(address);
            if (request is HttpWebRequest)
            {
                (request as HttpWebRequest).CookieContainer = CookieContainer;
            }
            return request;
        }
    }

}

I have one object of my webclient. There are many methods that use it. If two threads want to use that webClient to download I got error saying that webClent can run only one operation at the time. How can I modify that class so that when one thread is using it the other one have to wait. I need to lock it in some way.

You could use a Mutex for example.
When first client makes a request, you get the property of the mutex, releasing it when the call completes.
When other clients make request, first you wait for mutex and the job is done.

You can use the lock statement.
