使用BackgroundWorker线程的WPF等待光标

using System.Threading;
using System.Windows;

namespace BackgroundWorkerExample
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void StartButton_Click(object sender, RoutedEventArgs e)
        {
            // 设置等待光标
            Cursor = Cursors.Wait;

            // 创建BackgroundWorker线程
            BackgroundWorker worker = new BackgroundWorker();
            worker.DoWork += Worker_DoWork;
            worker.RunWorkerCompleted += Worker_RunWorkerCompleted;
            worker.RunWorkerAsync();
        }

        private void Worker_DoWork(object sender, DoWorkEventArgs e)
        {
            // 在后台线程中执行耗时操作
            Thread.Sleep(5000);
        }

        private void Worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            // 在UI线程中更新界面
            Cursor = Cursors.Arrow;
            MessageBox.Show("操作完成");
        }
    }
}
