在网上查找了不少的资料，可以说大同小异，概念性的东西网上一搜一堆，今天把反射的东西整理了一下，供大家使用，我保证我这里是最全面的东西，当然也是基础的东西，在学好了这一切的基础上，大家可以学习反射的具体插件等应用，老鸟就不用看了。首先我们建立一个类库，将它生成为HelloWorld.dll，
- using System;
- namespace Webtest
- {
- public interface interface1
- {
- int add();
- }
- public class ReflectTest:interface1
- {
- public String Write;
- private String Writec;
- public String Writea
- {
- get
- {
- return Write;
- }
- set
- {
- Write = value;
- }
- }
- private String Writeb
- {
- get
- {
- return Writec;
- }
- set
- {
- Writec = value;
- }
- }
- public ReflectTest()
- {
- this.Write = "Write";
- this.Writec = "Writec";
- }
- public ReflectTest(string str1,string str2)
- {
- this.Write = str1;
- this.Writec = str2;
- }
- public string WriteString(string s,int b)
- {
- return "欢迎您，" + s + "---" + b; ;
- }
- public static string WriteName(string s)
- {
- return "欢迎您光临，" + s;
- }
- public string WriteNoPara()
- {
- return "您使用的是无参数方法";
- }
- private string WritePrivate()
- {
- return "私有类型的方法";
- }
- public int add()
- {
- return 5;
- }
- }
- }
- 然后,建立再建立一个项目引入该HelloWorld.dll
- using System;
- using System.Threading;
- using System.Reflection;
- class Test
- {
- delegate string TestDelegate(string value,int value1);
- static void Main()
- {
- //Assembly t = Assembly.LoadFrom("HelloWorld.dll"); 与下面相同的效果
- Assembly t = Assembly.Load("HelloWorld");
- foreach (Type aaa in t.GetTypes())
- {
- //Console.Write(aaa.Name); //显示该dll下所有的类
- }
- Module[] modules = t.GetModules();
- foreach (Module module in modules)
- {
- //显示模块的名字本例为"HelloWorld.dll"
- //Console.WriteLine("module name:" + module.Name);
- }
- //得到具体的类的类型,和下面一个效果
- Type a = typeof(Webtest.ReflectTest);
- //Type a = t.GetType("Webtest.ReflectTest");//
- //Console.Write(a.Name);
- string[] bb =...{ "aaaa", "bbbbb" };
- //创建该类的实例,后面的bb为有参构造函数的参数
- object obj = Activator.CreateInstance(a,bb);
- //object obj = t.CreateInstance("Webtest.ReflectTest");
- MethodInfo[] miArr = a.GetMethods();
- foreach (MethodInfo mi0 in miArr)
- {
- //Console.Write(mi0.Name); //显示所有的共有方法
- }
- MethodInfo mi = a.GetMethod("WriteString");//显示具体的方法
- object[] aa=...{"使用的是带有参数的非静态方法",2};
- string s = (string)mi.Invoke(obj,aa); //带参数方法的调用
- MethodInfo mi1 = a.GetMethod("WriteName");
- String[] aa1 =...{"使用的是静态方法"};
- string s1 = (string)mi1.Invoke(null, aa1); //静态方法的调用
- MethodInfo mi2 = a.GetMethod("WriteNoPara");
- string s2 = (string)mi2.Invoke(obj, null); //不带参数的方法调用
- MethodInfo mi3 = a.GetMethod("WritePrivate",BindingFlags.Instance |
- BindingFlags.NonPublic);
- string s3 = (string)mi3.Invoke(obj, null); //私有类型方法调用
- //Console.Write(s3);
- PropertyInfo[] piArr = a.GetProperties(BindingFlags.Instance
- | BindingFlags.NonPublic | BindingFlags.Public);
- foreach (PropertyInfo pi in piArr)
- {
- //Console.Write(pi.Name); //显示所有的方法
- }
- PropertyInfo pi1=a.GetProperty("Writea");
- //pi1.SetValue(obj, "Writea", null);
- //Console.Write(pi1.GetValue(obj,null));
- PropertyInfo pi2 = a.GetProperty("Writeb",
- BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public);
- pi2.SetValue(obj, "Writeb", null);
- //Console.Write(pi2.GetValue(obj, null));
- FieldInfo fi1 = a.GetField("Write");
- //Console.Write(fi1.GetValue(obj));
- ConstructorInfo[] ci1 = a.GetConstructors();
- foreach (ConstructorInfo ci in ci1)
- {
- //Console.Write(ci.ToString()); //获得构造函数的形式
- }
- ConstructorInfo asCI = a.GetConstructor(new Type[] ...{
- typeof(string), typeof(string) });
- //Console.Write(asCI.ToString());
- Webtest.interface1 obj1 =
- (Webtest.interface1)t.CreateInstance("Webtest.ReflectTest");
- Webtest.ReflectTest obj2 =
- (Webtest.ReflectTest)t.CreateInstance("Webtest.ReflectTest");
- //Console.Write(obj1.add());典型的工厂模式
- foreach (Type tt in t.GetTypes())
- {
- if (tt.GetInterface("interface1")!=null)
- {
- Webtest.interface1 obj3 = (Webtest.interface1)Activator.CreateInstance(a);
- //Console.Write(obj3.add());
- }
- }
- TestDelegate method = (TestDelegate)Delegate.CreateDelegate(typeof(TestDelegate), obj,
- "WriteString");
- //动态创建委托的简单例子
- Console.Write(method("str1", 2));
- Console.Read();
- }
- }
在这里我把我们常用的方法,属性,等全部整理了出来,大家不要嫌弃乱,静下心来,自己按照我的分隔一部分一部分的来,保证你对反射的学习,会事半功倍.当然有关于其方法我会继续补充,想了这么些就先写下来吧.
