错误 Xaml 命名空间 [英] Error Xaml namespace

问题描述

我正在学习实现值转换器的教程.我收到此代码的错误:

I am following a tutorial to implement a value converter. I receive an error for this code:

public class BooleanToVisibilityConverter : IValueConverter
{
    //
}

<Application
x:Class="TestApp10.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TestApp10"
RequestedTheme="Light">
<Application.Resources>
    <local:BooleanToVisibilityConverter x:Key="TrueToVisibleConverter" />
    <local:BooleanToVisibilityConverter x:Key="FalseToVisibleConverter" IsReversed="True" />
</Application.Resources>

出现错误

命名空间using:TestApp10"中不存在名称BooleanToVisibilityConverter"

The name "BooleanToVisibilityConverter" does not exist in the namespace "using:TestApp10"

函数在 App.xaml.cs 文件中定义.

The function is defined in the App.xaml.cs file.

谢谢.
