.net 反射访问私有变量和私有方法

以下为本次实践代码：

 using System;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Linq;
 using System.Reflection;
 using System.Text;
 using System.Threading.Tasks;

 namespace ConsoleTest
 {
     class Program
     {
         static void Main(string[] args)
         {
             //反射读取类私有属性
             Person per = new Person("ismallboy", "");
             Type t = per.GetType();
             //获取私有方法
             MethodInfo method = t.GetMethod("GetStuInfo", BindingFlags.NonPublic | BindingFlags.Instance);
             //访问无参数私有方法
             string strTest = method.Invoke(per, null).ToString();
             //访问有参数私有方法
             MethodInfo method2 = t.GetMethod("GetValue", BindingFlags.NonPublic | BindingFlags.Instance);
             object[] par = new object[];
             par[] = "ismallboy";
             par[] = ;
             string strTest2 = method2.Invoke(per, par).ToString();

             //获取私有字段
             PropertyInfo field = t.GetProperty("Name", BindingFlags.NonPublic | BindingFlags.Instance);
             //访问私有字段值
             string value = field.GetValue(per).ToString();
             //设置私有字段值
             field.SetValue(per, "new Name");
             value = field.GetValue(per).ToString();
         }
     }

     /// <summary>
     /// 个人信息
     /// </summary>
     class Person
     {
         private string Name { get; set; }
         private string StuNo { get; set; }

         public Person(string name, string stuNo)
         {
             this.Name = name;
             this.StuNo = stuNo;
         }

         private string GetStuInfo()
         {
             return this.Name;
         }

         private string GetValue(string str, int n)
         {
             return str + n.ToString();
         }
     }
 }

如果使用dynamic的话，也可以如下：

 using System;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Linq;
 using System.Reflection;
 using System.Text;
 using System.Threading.Tasks;

 namespace ConsoleTest
 {
     class Program
     {
         static void Main(string[] args)
         {
             //反射读取类私有属性
             dynamic per = new Person("ismallboy", "");
             Type t = per.GetType();
             //获取私有方法
             MethodInfo method = t.GetMethod("GetStuInfo", BindingFlags.NonPublic | BindingFlags.Instance);
             //访问无参数私有方法
             string strTest = method.Invoke(per, null);
             //访问有参数私有方法
             MethodInfo method2 = t.GetMethod("GetValue", BindingFlags.NonPublic | BindingFlags.Instance);
             object[] par = new object[];
             par[] = "ismallboy";
             par[] = ;
             string strTest2 = method2.Invoke(per, par);

             //获取私有字段
             PropertyInfo field = t.GetProperty("Name", BindingFlags.NonPublic | BindingFlags.Instance);
             //访问私有字段值
             string value = field.GetValue(per);
             //设置私有字段值
             field.SetValue(per, "new Name");
             value = field.GetValue(per);
         }
     }

     /// <summary>
     /// 个人信息
     /// </summary>
     class Person
     {
         private string Name { get; set; }
         private string StuNo { get; set; }

         public Person(string name, string stuNo)
         {
             this.Name = name;
             this.StuNo = stuNo;
         }

         private string GetStuInfo()
         {
             return this.Name;
         }

         private string GetValue(string str, int n)
         {
             return str + n.ToString();
         }
     }
 }
