基于dynamic，动态给强类型Model扩展属性

直接上代码

List<TestModel> testList = new List<TestModel>();

testList.Add(new TestModel { Id = 1, Name = "A" });

testList.Add(new TestModel { Id = 2, Name = "B" });

testList.Add(new TestModel { Id = 3, Name = "C" });

List<dynamic> test = new List<dynamic>();

foreach (var item in testList)

{

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

var dic = (IDictionary<string, object>)dobj;

var t = item.GetType();

var properties = t.GetProperties();

// 循环赋值原Model中的值

foreach (var propertyInfo in properties)

{

var propertyName = propertyInfo.Name;

dic[propertyName] = propertyInfo.GetValue(item);

}

// 动态扩展属性

dic["Age"] = 3;

test.Add(dic);

}

示例Model

public class TestModel

{

public int Id { get; set; }

public string Name { get; set; }

}
