Question

我的Resources文件夹中有ResourceDictionary.xaml文件，里面有一些样式，我需要在我的.cs文件和xaml文件中使用它以及如何使用它？

这是我的ResourceDictionary.xaml：

<ResourceDictionary

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

我们通常以这种方式在.cs文件中以编程方式执行此操作

button.Style = (Style)App.Current.Resources["MainScreenButtonStyle"];

但是我们如何在Phone类库项目中访问？

Answer 1

实际上，在您的类库项目中包含ResourceDictionary.xaml文件非常简单，并且您有类似的内容：

 public Button CreateButton() 
        {
            Button b = new Button();
            Application.Current.Resources.Source = new Uri("/ResourceDictionary.xaml", UriKind.Relative);
            b.Style = (Style)Application.Current.Resources["MainScreenButtonStyle"];
            return b;
        }

Answer 2

您必须将资源xaml添加到App.xaml以自动检测它：

<Application.Resources>
    <ResourceDictionary x:Key="myDict">
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="ResourceDictionary.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

如何在Windows Phone类库项目中使用ResourceDictionary
