如何在Silverlight 3/WP7中使用类似于DynamicObject的东西? [英] How to use something similar to DynamicObject in Silverlight 3 / WP7?

问题描述

如何使用动态语言运行时(DLR)或其他方法在SILVERLIGHT 3(！)和WP7(无C#4.0！)中模仿System.Dynamic.DynamicObject..

How can you use Dynamic Language Runtime (DLR) or something else to mimic System.Dynamic.DynamicObject in SILVERLIGHT 3 (!) and WP7 (no C# 4.0!)..

我想做的是实现自动动态创建的数据绑定属性.

What I want to do is implement automatic dynamically created properties for databinding.

推荐答案

DLR可以与WP7一起使用.
Iron Ruby从版本1.1 支持Windows Phone 7.

The DLR can be used with WP7.
Iron Ruby supports Windows Phone 7 from version 1.1.

DynamicObject可作为.Net 4.0之前的扩展

DynamicObject was available as an extension prior to .Net 4.0

如果您乐于使用C#以外的语言，则可以选择.

If you're happy using a language other than C# then this could be an option.
There's a good article on using IronRuby on Windows Phone 7 at http://msdn.microsoft.com/en-us/magazine/ff960707.aspx.

作为替代方案，您可以使用匿名类型，而不使用动态类型吗?我认为您可能绑定的选项数量不限.

As an alternative, could you use anonymous types, rather than dynamic ones? I assume that there isn't an infinite number of options you're potentially binding to.

如果您确实想使用匿名类型，则必须设置

If you do want to use anonymous types you must set

[assembly: System.Runtime.CompilerServices.InternalsVisibleTo("System.Windows")]

使框架能够解析绑定.

大概是从外部系统获取动态对象.您是否不能在应用程序和外部系统之间添加包装层，以将对象转换为POCO，而不是动态对象.

Presumably you're getting you dynamic objects from an external system. Could you not add a wrapper layer between your app and the external system to turn the objects into POCOs rather than dynamic objects.
