提供一个思路，看下能用不：

    using System.Windows;
    using System.Windows.Controls;
    
    namespace WinForm
    {
        /// <summary>
        /// UserControl1.xaml 的交互逻辑
        /// </summary>
        public partial class UserControl1 : UserControl
        {
            MyThread mythread;
            System.Threading.Thread navT;
    
            public UserControl1()
            {
                InitializeComponent();
                mythread = new MyThread();
                navT = new System.Threading.Thread(mythread.Navigate);
                navT.Start();
            }
    
            /// <summary>
            /// 点击重新开启线程
            /// </summary>
            private void Button_Click(object sender, RoutedEventArgs e)
            {
                navT.Abort();
                navT.Start();
            }
        }
    
        /// <summary>
        /// 自定义线程类
        /// </summary>
        class MyThread
        {
            public MyThread() { }
            public void Navigate()
            {
                System.Threading.Thread.Sleep(3 * 60 * 1000);//3分钟
                //
                //TODO:窗体跳转
                //
            }
        }
    }
