在WPF中使用MVVM进行后台剪贴板监控，并在视图中绑定复制的上下文

namespace YourNamespace
{
    public class ViewModel : BindableBase
    {
        private string clipboardText;
        public string ClipboardText
        {
            get { return clipboardText; }
            set { SetProperty(ref clipboardText, value); }
        }

        public ICommand MonitorClipboardCommand { get; }

        public ViewModel()
        {
            MonitorClipboardCommand = new DelegateCommand(MonitorClipboard);
        }

        private void MonitorClipboard()
        {
            Clipboard.Clear();
            Clipboard.SetText(ClipboardText);
        }
    }
}
