问题描述

有没有办法在silverlight 导航应用程序中获取上一页网址.我正在使用导航服务.

Is there any way to get previous page url in silverlight navigation application. I am using navigation Service.

推荐答案

导航历史无法获取，可以通过监听导航服务事件自行存储NavigationService.Navigated(或 Frame.Navigated框架导航).

There is no way to get the navigation history, you can store it by yourself by listening the navigation service event NavigationService.Navigated (or Frame.Navigated for frame navigation).

private List<Uri> _navigationHistory = new List<Uri>();

void  onNavigated(object sender, NavigationEventArgs e)
{
    _navigationHistory.Add(e.Uri);
}

private Uri getBackUri()
{
        return _navigationHistory.Count > 1
            ? _navigationHistory[_navigationHistory.Count - 2]
            : null;
}
