C#類的屬性遍歷及屬性值獲取

1、定義一個類

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

2、獲取屬性

方法一、定義一個類的對象獲取

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

方法二、通過類獲取

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

3、通過屬性名獲取對象屬性值

p.Name = "張三";
var name = p.GetType().GetProperty("Name").GetValue(p, null);
Console.WriteLine(name);

4、完整代碼及結果顯示

var properties = typeof(Person).GetProperties();
foreach (System.Reflection.PropertyInfo info in properties)
{
   Console.WriteLine(info.Name);
}
Console.WriteLine("另一種遍歷屬性的方法：");
 
Person p = new Person();
foreach (System.Reflection.PropertyInfo info in p.GetType().GetProperties())
{
   Console.WriteLine(info.Name);
}
            
Console.WriteLine("通過屬性值獲取屬性：");
 
p.Name = "張三";
var name = p.GetType().GetProperty("Name").GetValue(p, null);
Console.WriteLine(name);
Console.ReadLine();
