本例項程式碼演示瞭如何利用泛型T,遍歷任意類的所有屬性:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace GenericT { class Program { /// <summary> /// 本例項程式碼演示瞭如何利用泛型T,遍歷任意類的所有屬性 /// </summary> /// <param name="args"></param> private static string Property2String<T>(T model) { //獲取例項的type Type t = model.GetType(); //把所有屬性轉化為list var list = t.GetProperties().ToList(); string text = string.Empty; //遍歷屬性 list.ForEach(x => { object value = x.GetValue(model); //屬性值和屬性名轉為字串 var str = string.Format(" [{0}={1}] ", x.Name, value.ToString()); text += str; }); return text; } static void Main(string[] args) { //使用方法 //遍歷Student類的所有屬性 var text = Property2String<Student>(new Student() { Name = "Levi", Id = "abcd", Age = 18 }); Console.WriteLine(text); //遍歷School類的所有屬性 text = Property2String<School>(new School() { Name = "college", Address = "beijing", ClassCount = 99 }); Console.WriteLine(text); Console.Read(); } } //純屬性的類 public class Student { public string Name { get; set; } public string Id { get; set; } public int Age { get; set; } } //純屬性的類 public class School { public string Name { get; set; } public string Address { get; set; } public int ClassCount { get; set; } } }
