C#类的属性遍历及属性值获取

1、定义一个类

public class Person
{
     public string Name { get; set; }
     public int ID { get; set; }
}

2、获取属性

方法一、定义一个类的对象获取

Person p = new Person();
foreach (System.Reflection.PropertyInfo info in p.GetType().GetProperties())
{
    Console.WriteLine(info.Name);
}

方法二、通过类获取

var properties = typeof(Person).GetProperties();
foreach (System.Reflection.PropertyInfo info in properties)
{
   Console.WriteLine(info.Name);
}

3、通过属性名获取对象属性值

p.Name = "张三";
var name = p.GetType().GetProperty("Name").GetValue(p, null);
Console.WriteLine(name);

4、完整代码及结果显示

var properties = typeof(Person).GetProperties();
foreach (System.Reflection.PropertyInfo info in properties)
{
   Console.WriteLine(info.Name);
}
Console.WriteLine("另一种遍历属性的方法：");
 
Person p = new Person();
foreach (System.Reflection.PropertyInfo info in p.GetType().GetProperties())
{
   Console.WriteLine(info.Name);
}
            
Console.WriteLine("通过属性值获取属性：");
 
p.Name = "张三";
var name = p.GetType().GetProperty("Name").GetValue(p, null);
Console.WriteLine(name);
Console.ReadLine();
