我在编写 Esurvey 应用程序(使用 Windows Store C# XAML)时遇到问题,我真的需要帮助。我需要创建一个包含所有结果(单选按钮选择和文本输入)的 .csv 数据库,但我不确定从哪里开始。

有人可以帮我解决这个问题吗?我正在使用 Visual Studio Community 2013。

Here is a screenshot of my application in case you need a reference.

这是我的老师想要的输出,但我不知道如何制作它:(

最佳答案

你可以这样做,其中“greetingOutputText”是关键

private void navigationHelper_LoadState(object sender, LoadStateEventArgs e)
{
// Restore values stored in session state.
if (e.PageState != null && e.PageState.ContainsKey("greetingOutputText"))
{
greetingOutput.Text = e.PageState["greetingOutputText"].ToString();
}
}



private void navigationHelper_SaveState(object sender, SaveStateEventArgs e)
{
e.PageState["greetingOutputText"] = greetingOutput.Text;

}

link会帮助你。
