在XAML中定义的WPF窗口上使用泛型参数

public class GenericWindow<T> : Window where T : class
{
    public T DataContext { get; set; }

    public GenericWindow()
    {
        InitializeComponent();
    }
}

                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:YourNamespace">

   <Style TargetType="{x:Type local:GenericWindow}">
       <Setter Property="Title" Value="Generic Window" />
       <Setter Property="Width" Value="800" />
       <Setter Property="Height" Value="600" />
       <Setter Property="DataContext" Value="{Binding RelativeSource={RelativeSource Self}, Path=DataContext}" />
       <Setter Property="Content">
           <Setter.Value>
                <Grid>
                    <!-- 在这里定义窗口的内容 -->
                </Grid>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

var window = new GenericWindow<YourDataContextType>();
window.DataContext = new YourDataContextType();
window.ShowDialog();

<TextBlock Text="{Binding YourProperty}" />
