从嵌入在 WinForms 中的 WPF 控件获取 Generic.xaml [英] Getting Generic.xaml working from WPF control embedded in WinForms

问题描述

我有一个嵌入在 Windows 窗体中的 WPF 控件，它工作正常.但是我在 Themes/Generic.xaml 中拥有 WPF 项目的所有样式.当我将 WPF 控件嵌入到 Windows 窗体 ElementHost 控件中时，不会选取这些样式.

I have a WPF control embedded in a Windows Form, which works ok. But I have all my styles for the WPF project inside Themes/Generic.xaml. When I embed the WPF control inside a Windows Forms ElementHost control, these styles are not picked up.

我是否需要更改 WPF 视图以在其资源部分中显式包含样式，还是仍应自动选取 generic.xaml 文件?

Do I need to change the WPF view to explicitly include the styles in its Resources section, or should the generic.xaml file be picked up automatically still?

推荐答案

Themes/Generic.xaml 是否在不同的程序集中?

Is Themes/Generic.xaml in a different assembly?

问题是应用程序没有找到定义样式的 ResourceDictionary.

The problem is that the application is not finding the ResourceDictionary where the styles are defined.

您可以做的是创建一个像这样的静态 SharedDictionaryManager 类:

What you can do is to create a static SharedDictionaryManager class like this one:

public static class SharedDictionaryManager
{
    private static ResourceDictionary _sharedDictionary;
    internal static ResourceDictionary SharedDictionary
    {
        get
        {
            if (_sharedDictionary == null)
            {
                System.Uri resourceLocater =
                    new System.Uri("/assembly;component/Themes/Generic.xaml",
                                    System.UriKind.Relative);

                _sharedDictionary =
                    (ResourceDictionary)Application.LoadComponent(resourceLocater);
            }

            return _sharedDictionary;
        }
    }
}

当你创建 HostControl 时，你添加资源字典来做控制:

And when you create the HostControl you add the resource dictionary do the control:

ctrl.Resources.MergedDictionaries.Add(SharedDictionaryManager.SharedDictionary);

如果您有多个资源字典，您可以为每个资源字典设置一个这样的属性，或者您可以拥有一个加载所有资源字典然后合并所有字典的属性.

If you have more than one resource dictionary you can have one property like this for each one or you can have a property that loads all the resource dictionaries and then merge all dictionaries.

现在，应该会自动选择您需要的样式.

Now, the style you need should be automatically picked.
