C# 我在文本框中输入的数据没有分配给UWP应用程序中的值变量

我正在使用模板10开发一个简单的UWP应用程序。我想在文本框中输入货币数据。我的理解是，我应该在视图模型中使用字符串变量。因此，目前我只是确保在运行应用程序时输入的数据能够正常工作。但事实并非如此。在运行或调试它时，如果我输入类似“10”（不带双引号）的值，则变量的赋值为“0”。这对我来说毫无意义。以下是XAML：

<TextBox
    x:Name="HourlyTextBox"
    Style="{StaticResource CommonTextboxStyle}"
    Text="{x:Bind ViewModel.Hourly, Mode=TwoWay}" />

下面是代码背后的代码：

using Windows.UI.Xaml.Controls;

namespace SalaryConversion.Views
{
    public sealed partial class MainPage : Page
    {
        private SalaryUnitsEnum lastHadFocus;

        public MainPage()

            InitializeComponent();
            NavigationCacheMode = 
Windows.UI.Xaml.Navigation.NavigationCacheMode.Enabled;
        }

由于Richard Zhang建议查看我的代码，我在那里发现我以前编写了一些代码来处理屏幕上的控件。正是该代码将值重置为0（间接）。我不久前就写了这段代码，所以我把它忘得一干二净

理查德，谢谢你提出这个建议。它帮助我了解了我所做的事情，并且在查看之后，我能够轻松地解决它。

嗨，你能提供有关

\uuuz=Set（）

的详细信息吗？如果不使用ref，只使用normal

hourly=value有效。很抱歉Richard，我之前没有看到这个。在本例中，我在创建项目时使用了模板10。Set（）函数来自模板10。很抱歉，我也使用了模板10，但我无法重现该问题，它的值是正确的。你能给出一个完整的循环步骤或最小的可运行代码吗？嗨，Richard，我想你是指XAML。这里有一个来自页面XAML的较大片段：对不起，我没有说清楚。我需要你的代码隐藏代码，你可以修改你的问题描述。这包括创建
ViewModel
的过程，这对解决问题有很大帮助。
