Simulate NavigateAndWait with a WebBrowser using yield return

I'm working on an application that it's been giving me some trouble, partly because of a function I made called NavigateAndWait(string url) that navigates and then waits in a loop like this:

while(!DocCompleted) Application.DoEvents();

DocCompleted is a bool that changes to true whenever DocumentCompleted is called. I keep reading everywhere that using Application.DoEvents() is in general a bad idea. And I also think it is. I was using it mainly as a temporary way of simplifying my code. The problem is that I assumed there would be another way to make a NavigateAndWait function, and I made the whole program based on this assumption. So I came up with this way of simulating a NavigateAndWait function without actually waiting using yield return. This is just a sample application that illustrates the idea (see Get() in Form1). So before I go ahead and change my whole code I would like to know your opinion. It might be actually a terrible idea because of something I'm missing (I tend to miss stuff :-)).

public partial class Form1 : Form
{
    BrowserWrapper bw;

    public Form1()
    {
        InitializeComponent();
        bw = new BrowserWrapper(webBrowser1);
    }

    public IEnumerable<string> Get()
    {
        yield return "www.google.com";      // simulates NavigateAndWait("www.google.com");
        yield return "www.yahoo.com";       // simulates NavigateAndWait("www.yahoo.com");
        yield return "www.hotmail.com";     // simulates NavigateAndWait("www.hotmail.com");
    }

    private void button1_Click(object sender, EventArgs e)
    {
        bw.CallEnumerator(Get());
    }
}

public class BrowserWrapper
{
    WebBrowser Browser;
    IEnumerator<string> Enumerator = null;

    public BrowserWrapper(WebBrowser browser)
    {
        Browser = browser;
        Browser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(Browser_DocumentCompleted);
    }

    void Browser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        if(Browser.ReadyState == WebBrowserReadyState.Complete && e.Url == Browser.Url)
        if (Enumerator != null)
        {
            if (Enumerator.MoveNext()) Browser.Navigate(Enumerator.Current);
        }
    }

    public void CallEnumerator(IEnumerable<string> enumerable)
    {
        Enumerator = enumerable.GetEnumerator();
        if (Enumerator.MoveNext())
        {
            Browser.Navigate(Enumerator.Current);
        }
    }
}
