动态地添加属性的ExpandoObject [英] Dynamically adding properties to an ExpandoObject

问题描述

我想在运行时动态性能到ExpandoObject补充。因此，例如，添加一个字符串属性调用NewProp我想写点东西像

 变种x =新ExpandoObject（）;
x.AddProperty（NewProp，System.String）;
 

这是容易做到？

解决方案

 动态X =新ExpandoObject（）;
x.NewProp =的String.Empty;
 

或者

 变种x =新ExpandoObject（）作为IDictionary的＆LT;字符串对象＆gt ;;
x.Add（NewProp的String.Empty）;
 

I would like to dynamically add properties to a ExpandoObject at runtime. So for example to add a string property call NewProp I would like to write something like

var x = new ExpandoObject();
x.AddProperty("NewProp", System.String);

Is this easily possible?

解决方案

dynamic x = new ExpandoObject();
x.NewProp = string.Empty;

Alternatively:

var x = new ExpandoObject() as IDictionary<string, Object>;
x.Add("NewProp", string.Empty);
