public void Demo(){    MessageBox.Show("hello");}

1.传递方法

<Button Content="Demo"        cal:Message.Attach="Demo" />

2.使用事件传递

(1)

<Button Content="Demo"        cal:Message.Attach="[Event Click] = [Action Demo]" />

(2)附加事件(好像有bug)

<StackPanel cal:Message.Attach="[AttachedEvent Button.Click] = [Action Demo]">    <Button Content="Divide (Stack)" />    <Button Content="Divide (Stack)" /></StackPanel>

3.事件连写(分号相隔)

<Button Content="Demo"        cal:Message.Attach="[Event Click] = [Action Demo];[Event Loaded] = [Action Demo]" />

其他事件请参考此处

4.参数传递

(1)

public void Demo(string str){    MessageBox.Show(str);}

<Button Content="Demo"        cal:Message.Attach="Demo('hello')" />

(2)支持元素对象获取

<TextBox x:Name="demoBox" /><Button Content="Demo"        cal:Message.Attach="Demo(demoBox.Text)" />

(3)支持内置参数解析

http://caliburn.codeplex.com/wikipage?title=Parameters&referringTitle=Documentation

public void Demo(object sender,EventArgs args){   }

<Button Content="Demo"        cal:Message.Attach="Demo($source,$eventArgs)" />

(4)支持返回值传递

public int Demo(){    return 1;}

<TextBox x:Name="demoBox" /><Button Content="Demo"        cal:Message.Attach="[Action Demo : demoBox.Text]" />

(5)支持绑定模式

<TextBox x:Name="demoBox" /><Button Content="Demo"        cal:Message.Attach="[Action Demo(demoBox.Text:TwoWay)]" />
