为什么没有找到我的ViewModel？ [英] Why is my ViewModel not found?

问题描述

为什么VS找不到我的文件？

VS错误图像和文本：

严重性代码说明项目文件行抑制状态
错误CS0246 无法找到类型或命名空间名称AudioFile（您是否缺少一个使用指令或汇编引用？）reOrder C：\Users\kloud\Documents\Visual Studio 2015\Projects\reOrder\reOrder\ReorderPage.xaml.cs 27 Active

我重新创建了项目，看看Visual Studio是否正在做一些我看不到/理解并广泛检查正在工作的代码（正确找到项目和绑定）以查看差异的位置。我找不到任何线索。

编辑：我在Windows 10周年纪念更新中使用Visual Studio 2015社区版。此外，在以前的项目中，VS没有找到并绑定到模型的麻烦。

下面的完整代码。

AudioItem模型
（skipped usings）

 命名空间reOrder.Models 
 {
 public class AudioItem 
 {
 public string Path {get ;组; } 
 
 public string Name {get;组; } 
 
 public int Duration {get;组; 
} 
} 
  

解决方案

即使重建解决方案，我也遇到了同样的问题。我做过的一种解决方法是转到文件浏览器中的.csproj文件，现在在itemgroup标签下编辑添加：

 < Compile Include =ViewModels\AudioItemModel .cs> 
< Dependent Upon> Reorder.xaml< / Dependent Upon> 
< / Compile> 
  

保存并关闭它，然后重建它，现在将检测viewmodel。

Why can't VS find my file?

VS Error Image and Text:

Severity Code Description Project File Line Suppression State Error CS0246 The type or namespace name 'AudioFile' could not be found (are you missing a using directive or an assembly reference?) reOrder C:\Users\kloud\Documents\Visual Studio 2015\Projects\reOrder\reOrder\ReorderPage.xaml.cs 27 Active

I recreated the project to see if Visual Studio was doing something I couldn't see/understand and checked extensively with code that is working(correctly finds the item and binds) to see where the differences are. I couldn't find any clues though.

edit: I am using Visual Studio 2015 Community Edition on Windows 10 Anniversary Update. Also, in previous projects VS didn't have trouble finding and binding to a model.

Full code below.

Reorder Page

<Page
    x:Class="reOrder.ReorderPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:viewModels="using:reOrder.Models"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <Grid.RowDefinitions>

            <RowDefinition Height="*"/>
            <RowDefinition Height="auto"/>
        </Grid.RowDefinitions>

        <ListView Grid.Row="1"
                  ItemsSource="{x:Bind AudioFiles}">
            <ListView.ItemTemplate>
                <DataTemplate x:DataType="viewModels:AudioItem">
                    <StackPanel>
                        <TextBlock Text="{x:Bind Name}"/>
                    </StackPanel>
                </DataTemplate>
            </ListView.ItemTemplate>
        </ListView>
    </Grid>
</Page>

AudioItem Model (skipped usings)

namespace reOrder.Models
{
    public class AudioItem
    {
        public string Path { get; set; }

        public string Name { get; set; }

        public int Duration { get; set; }
    }
}

解决方案

I had the same problem even after rebuilding the solution.One workaround i did was Go to your .csproj file in file explorer and now edit under itemgroup tag add this:

<Compile Include="ViewModels\AudioItemModel .cs">
  <DependentUpon>Reorder.xaml</DependentUpon>
</Compile>

Save it and close it and then rebuild it and now it will detect the viewmodel.
