向动态对象动态添加属性

本文关键字:动态 属性 添加 对象 | 更新日期: 2023-09-27 18:16:29

我有这个

dynamic d = new ExpandoObject();
d.Name = attribute.QualifiedName.Name;

所以,我知道d将有一个属性名。现在,如果我在编译时不知道属性的名称,我如何将该属性添加到动态。i found this SO Question

所以,有一个调用绑定等复杂的概念,一开始很难理解。有更简单的方法吗?

向动态对象动态添加属性

dynamic d = new ExpandoObject();
((IDictionary<string,object>)d)["test"] = 1;
//now you have d.test = 1

这是一个更干净的方法

var myObject = new ExpandoObject() as IDictionary<string, Object>;myObject.Add("Country", "Ireland");

你也可以这样做:-

Dictionary<string,object> coll = new Dictionary<string,object>();
    coll.Add("Prop1","hello");
    coll.Add("Prop2",1);
    System.Dynamic.ExpandoObject obj = dic.Expando();
//You can have this ext method to better help
public static ExpandoObject Expando(this IEnumerable<KeyValuePair<string, object>> 
dictionary)
        {
            var expando = new ExpandoObject();
            var expandoDic = (IDictionary<string, object>)expando;
            foreach (var item in dictionary)
            {
                expandoDic.Add(item);
            }
            return expando;
        }
