An improved FindControl for Windows desktop and mobile.

A few days ago I posted some code containing an implementation for a Windows Forms version of FindControl. Aviad P. pointed out a correction and a way that the routine can be simlified. While I had intended the original code to do a breadth-first search, it was doing a combination of depth and breadth. The functionality could also be implemented with a single loop. The result of the messages, the resulting code from our communication, is shown below:

Control FindControl(string target) {
    return FindControl(this,target);
}
static Control FindControl(Control root, string target){
    if(root.Name == target)
        return root;
    List currentLevel = new List() { root };
    while (currentLevel.Count > 0)
    {
        Control match = currentLevel.FirstOrDefault(x => x.Name == target);
        if (match != null) return match;
        currentLevel = currentLevel.SelectMany(x => x.Controls.Cast()).ToList();
    }    return null;
}
