xaml中的一些使用方法

1. 构造对象

public class Food {  
    private string _name;  
    private Int32 _calories;  
    public Food(string name, Int32 calories) {  
        _name=name;  
        _calories=calories;  
    }  
}  

<my:Food>  
    <x:Arguments>  
        <x:String>Apple</x:String>  
        <x:Int32>150</x:Int32>  
    </x:Arguments>  
</my:Food>  

 

public Food TryLookupFood(string name)  
{  
  switch (name) {  
    case "Apple": return new Food("Apple",150);  
    case "Chocolate": return new Food("Chocolate",200);  
    case "Cheese": return new Food("Cheese", 450);  
    default: {return new Food(name,0);  
  }  
}  

<my:Food x:FactoryMethod="TryLookupFood">  
    <x:Arguments>  
        <x:String>Apple</x:String>  
    </x:Arguments>  
</my:Food>  

 2. 定义数组

<x:Array Type="sys:String">
                        <sys:String>String1</sys:String>
                        <sys:String>String2</sys:String>
                        <sys:String>String3</sys:String>
 </x:Array>
