C# 使用Caliburn.Micro.Contrib通用对话框

我对C#编程相当陌生。我开始使用MVVM模式和Caliburn.Micro框架开发WPF应用程序。我还添加了Caliburn.Micro.Contrib库，因为它包含一些有用的对话框

我试着在我的项目中使用它，但我无法让它工作。 当我单击应该显示对话框的按钮时，我看到一个空窗口，说明找不到视图：（Caliburn.Micro.Contrib.Dialogs.DialogViewModel`1[Caliburn.Micro.Contrib.Dialogs.Answer]）

我已设置Caliburn.Micro引导以嵌入CM Contrib程序集：

protected override IEnumerable<Assembly> SelectAssemblies()
{
    return base.SelectAssemblies().Concat(new Assembly[] { typeof(ResultExtensions).Assembly       }); 
}

我再次检查了源代码，找到了问题的根源。它存在于

DialogResult

类型中，特别是

IResult

的

Execute

方法中，该方法将上下文参数传递给引起问题的

WindowManager.ShowDialog（）

我进一步查看了一下，发现库作者写了一篇关于对话框的文章，评论中的某篇文章与您的问题相同，建议的解决方案是在引导程序的

Configure（）

方法中调用以下代码行：

FrameworkExtensions.ViewLocator.EnableContextFallback();

这里是到的链接，这里是

如果这不起作用，我没有别的话要说，我已经尽力了。

你能展示一下你的完整的引导程序吗？我已经编辑了我的帖子，但是我不认为这有什么特别之处。你的引导程序看起来很好，所以我不能告诉你可能有什么问题，但我可以建议Caliburn.Micro使用调试记录器（如中的调试记录器）记录它所做的一切，然后您将看到它无法定位该视图的原因，并从中继续。感谢提示，我已经激活了它，下面是我在日志中的内容：我理解您的意思，我刚刚尝试过（我已经尝试过了），但是运气不好，我遇到了同样的错误，事实上，CM试图找到完全相同的视图，当你更改DialogType类型时，它试图找到相应的视图。@Tarteens你所说的“当你更改DialogType类型时，它试图找到相应的视图”是什么意思，你能进一步解释一下吗？如果我设置DialogType。问题，在日志中，我有：未找到视图。搜索：Caliburn.Micro.Contrib.Dialogs.Dialog.Question。如果我设置了DialogType.Information，在日志中我有：View not found。搜索：Caliburn.Micro.Contrib.Dialogs.Dialog。Information@Tarteens我已经完全更改了答案，请检查编辑。感谢您的帮助，EnableContextFallback成功了。
