Question

出于某种原因，我收到Cannot find view for CaliburnPractice.ViewModel错误。我已经在这里查看了一些答案，但没有一个对我有用。我已将视图和视图模型放入单独的命名文件夹中，并且我已经覆盖了SelectedAssembly方法。到底是怎么回事？请参阅下面的代码。

ViewModel.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Caliburn.Micro;

namespace CaliburnPractice
{
    public class ViewModel : PropertyChangedBase
   {

   }
}

的App.xaml

<Application x:Class="CaliburnPractice.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:CaliburnPractice"
         >
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary>
                <local:Bootstrapper x:Key="bootstrapper" />
            </ResourceDictionary>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>

</Application.Resources>

PracticeView.xaml

<UserControl x:Class="CaliburnPractice.PracticeView"
         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:d="http://schemas.microsoft.com/expression/blend/2008" 
         mc:Ignorable="d" 
         d:DesignHeight="300" d:DesignWidth="300">
<Grid Width="300" Height="300" Background="LightBlue">

</Grid>

Bootstrapper.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Caliburn.Micro;
using System.Reflection;

namespace CaliburnPractice
{
    public class Bootstrapper : BootstrapperBase
    {
        public Bootstrapper()
        {
            Initialize();
        }
        protected override void OnStartup(object sender,         System.Windows.StartupEventArgs e)
        {
            base.OnStartup(sender, e);
            DisplayRootViewFor<ViewModel>();
        }
        protected override IEnumerable<System.Reflection.Assembly>     SelectAssemblies()
        {
            return new[]
            {
                Assembly.GetExecutingAssembly()
            };
        }
    }
}

因为它正在查找View，您的viewmodel被命名为ViewModel ...您列出的视图是PracticeView ...

ShellView - ＆gt; ShellViewModel

MainView - ＆gt; MainViewModel等......

因此，练习视图 - ＆gt; PracticeViewModel会得到解决....

SelectedAssembly用于不同DLL中的单独视图/视图模型

除非你不包括我们可能需要知道的任何内容......

找不到ViewModel的视图，即使重写了SelectedAssembly也是如此
