C#使用dynamic一行代码实现反射操作

// 定义一个类
public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Gender { get; set; }
}
// 创建一个对象并设定属性值
var person = new Person
{
????Name?=?"刘备",
????Age?=?30,
    Gender = "男"
};

// 使用反射获取属性值
var type = person.GetType();
var properties = type.GetProperties();
foreach (var property in properties)
{
    var value = property.GetValue(person);
    Console.WriteLine($"{property.Name}:{value}");
}

// 使用dynamic来简化反射实现
dynamic dynamicPerson = person;
Console.WriteLine($"Name:{dynamicPerson.Name}, Age:{dynamicPerson.Age}, Gender:{dynamicPerson.Gender}");

?#region?反射和dynamic的对比
 int times = 1000000;
 DynamicTest reflectTest = new DynamicTest();
 var addMethod = typeof(DynamicTest).GetMethod("Add");
 Stopwatch watchl = Stopwatch.StartNew();
 for (var i = 0;i< times; i++)
 { addMethod.Invoke(reflectTest, new object[] { 1, 2 }); }
 Console.WriteLine($"反射耗时:{watchl.ElapsedMilliseconds}毫秒"); 
  dynamic dynamicTest = new DynamicTest();
 Stopwatch watch2 = Stopwatch.StartNew();
 for (int i =0;i< times; i++)
      dynamicTest.Add(1,2);
?Console.WriteLine($"dynamic耗时:{watch2.ElapsedMilliseconds}?毫秒");
