Question

我正在使用c＃和WPF Web应用程序，我想构建一个简单的表单，其中包含两个用于用户输入的文本框（名称和电话号码）和一个“发送”按钮。当用户点击发送按钮时，它将重定向到另一个页面，并将显示（带有文本块）输入的值。

我试着阅读有关数据绑定的内容，但仍未成功使其正常工作。
1.如何将输入的值保存到变量中？
2.如何从第二页调用这些变量并显示保存的文本？

希望得到帮助，谢谢！

表单的xaml代码：

<TextBlock Height="20" Width="120" Margin="36,43,144,237">enter details:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,69,224,211">Name:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,103,224,177">Phone:</TextBlock>
<!--textboxes-->
<TextBox Height="20" Width="95" Margin="100,69,104,211" Name="getName" Background="Gray"/>
<TextBox Height="20" Width="95" Margin="100,103,105,177" Name="getPhoneNumber" Background="Gray"/>
<!--          -->
<Button Height="20" Width="50" Margin="218,103,32,177" Name="sendButton" Click="sendButton_Click">send</Button>

背后应该是什么代码？我只想在带有textblock的其他页面上显示输入的值。这是我用来重定向到“结果页面”的功能：

public void sendButton_Click(object sender, RoutedEventArgs e)
{
    Submit();
}

void Submit()
{
    Page2 resultpage = new Page2();
    NavigationService.Navigate(resultpage);
}

好的，由于Mike的回答，我成功地使它成功。

感谢Mike，对于其他用户来说，这个代码现在看起来如何：
表单页面xaml代码：

<TextBlock Height="20" Width="120" Margin="36,43,144,237">enter details:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,69,224,211">Name:</TextBlock>
<TextBlock Height="20" Width="40" Margin="36,103,224,177">Phone:</TextBlock>
<!--textboxes-->
<TextBox Height="20" Width="95" Margin="100,69,104,211" Name="getName" Background="Gray"/>
<TextBox Height="20" Width="95" Margin="100,103,105,177" Name="getPhoneNumber" Background="Gray"/>
<!--          -->
<Button Height="20" Width="50" Margin="218,103,32,177" Name="sendButton" Click="sendButton_Click">send</Button>

表单页面c＃代码背后：

    public partial class Page1 : Page
{
    public Page1()
    {
        InitializeComponent();
    }

    public void sendButton_Click(object sender, RoutedEventArgs e)
    {
        Submit();
    }

    void Submit()
    {
        Page2 resultpage = new Page2(getName.Text, getPhoneNumber.Text);
        NavigationService.Navigate(resultpage);
    }
}

结果页xaml代码：

    <Grid>
    <TextBlock x:Name="showName" Height="50" Width="100" Margin="65,125,73,125" Text="{Binding ElementName=showName, Path=Text}" />
</Grid>

结果页c＃代码背后：

        public Page2(string name, string phoneNumber)
    {
        InitializeComponent();
        showName.Text = name;
    }

再次感谢迈克：）

Answer 1

好的，我会做的。您可以在Page2的构造函数中创建参数：

public Page2(string name, string phoneNumber)
{
    //login to handle name and phone number

}

在您的第一页上，您只需使用xaml中的Name属性传递姓名和电话号码。

void Submit()
{
    Page2 resultpage = new Page2(getName.Text, getPhoneNumber.Text);
    NavigationService.Navigate(resultpage);
}

private void buttoncheck_Click(object sender, RoutedEventArgs e)
{
    Page2 p2 = new Page2();
    p2.textBlock1.Text = txtnavigation.Text;
    //txtnavigatevalue.Text = "";
    NavigationService.Navigate(p2);
}

TextBox在其他页面中输入到TextBlock
