x 命名空间中x:Type 的使用

若传入参数为类型的时候  用x:Type 指定此类型值

有如下一自定义按钮类型：

public class MyButton : Button
    {
        public Type MyUserType { get; set; }
        protected override void OnClick()
        {
            base.OnClick();
            Window win = Activator.CreateInstance(MyUserType) as Window;
            if (win != null)
            {
                win.ShowDialog();
            }
        }
    }

希望的效果是在点击此按钮的时候弹出另外一个MyWindow窗体

首相在当前窗体上放置此按钮

<local:MyButton x:Name="mybtn" Content="My Button" MyUserType="{x:Type Type=local:MyWindow}"></local:MyButton>

 

然后定义这个MyWindow窗体：

<Window x:Class="WpfApplication1.MyWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MyWindow" Height="300" Width="300" Loaded="Window_Loaded">
    <TextBlock x:Name="block" Text="Hello Buddy"></TextBlock>
</Window>
