c# dynamic动态类型和匿名类

dynamic类型

方法一：简单示例

dynamic expando = new System.Dynamic.ExpandoObject(); //动态类型字段 可读可写
expando.Id = 1;
expando.Name = "Test";
string json = Utils.ConvertJson.JsonEncode(expando);  //输出{Id:1,Name:'Test'}

 方法二：动态添加字段

List<string> fieldList = new List<string>() { "Name","Age","Sex"}; //From config or db

dynamic dobj = new System.Dynamic.ExpandoObject();

var dic = (IDictionary<string, object>)dobj;
foreach (var fieldItem in fieldList)
{
　　dic[fieldItem] = "set "+fieldItem+" value";  /*实现类似js里的 动态添加属性的功能
}

 方法三：枚举该对象所有成员，生成字符串，反序列化成动态对象
