Object model=Assembly.Load(“程序集”).CreateInstance(命名空间.类名);
object obj2 = Type.GetType("MyClass").GetMethod("Add").Invoke(obj,null);
obj2是返回值
Activator.CreateInstance会调用dll中类的构造函数，如果你的类里面没有提供无参的构造函数
Assembly _Assembly = Assembly.Load("程序集名"); Type _Type = _Assembly.GetType("完整类名"); Form _Form = (Form)Activator.CreateInstance(_Type); System.Reflection.EventInfo _EventInfo = _Type.GetEvent("RemoveFormHandler"); _EventInfo.AddEventHandler(_Form, new Com.Psi.UIBase.RemoveFormDelegate(RemoveForm)); System.Reflection.FieldInfo _FieldInfoSys = _Type.GetField("m_SysDataSet"); _FieldInfoSys.SetValue(_Form, this.m_TableDataSet); _Form.Show()
//创建对象 Assembly assembly = Assembly.LoadFile(); //Assembly assembly = Assembly.Load("Test2"); //Object obj1 = assembly.CreateInstance("Test2.Reflect.Operate", false);//assembly.CreateInstance内部调用Activator.CreateInstance //Object obj2 = assembly.CreateInstance("Test2.Reflect.Operate", false, BindingFlags.Default, Type.DefaultBinder, new Object[] { "123" }, System.Globalization.CultureInfo.CurrentCulture, new Object[] { }); //Object obj3 = Activator.CreateInstance(Type.GetType("Test2.Reflect.Operate")); //Object obj4 = Activator.CreateInstance(Type.GetType("Test2.Reflect.Operate"),"456"); //Type type = Type.GetType("Test2.Reflect.Operate"); 每次调用InvokeMemeber方法时，它必须先绑定到一个特定的成员，然后才能调用它。 如果每次调用一个成员时都让绑定器选择适当的成员，那么将是非常耗时的。。建议用：一次绑定，多次调用 //Object obj5 = type.InvokeMember("Operate", BindingFlags.CreateInstance, null, null, new Object[] { "789" }); //Assembly assembly = Assembly.Load("Test2"); //Type t = assembly.GetType("Test2.Reflect.Operate"); //ConstructorInfo constructorInfo = t.GetConstructor(new Type[] { typeof(string) }); //Object obj6 = constructorInfo.Invoke(new Object[] { "kkkkkkkk" }); //AppDomain appDomain = AppDomain.CurrentDomain; //内部也是调用的Activator.CreateInstance //ObjectHandle objHandle = appDomain.CreateInstance("Test2", "Test2.Reflect.Operate"); //Object obj7 = objHandle.Unwrap(); //除了数组和委托之外，其他都可以利用上述通过反射创建对象 //访问变量 //Assembly assembly = Assembly.Load("Test2"); //Object obj1 = assembly.CreateInstance("Test2.Reflect.Operate", false); //Type type = Type.GetType("Test2.Reflect.Operate"); //FieldInfo fieldInfo = type.GetField("_Address"); //获取私有字段 ("_Address",BindingFlags.NoPublic|bindingFlags.instance) //Object ret= fieldInfo.GetValue(obj1);
//私有静态字段，BindingFlags的次序必须一致。FieldInfo fieldInfo = type.GetField("_instance", BindingFlags.Static | BindingFlags.NonPublic);
//属性 //Assembly assembly = Assembly.Load("Test2"); //Object obj1 = assembly.CreateInstance("Test2.Reflect.Operate", false); //Type type = Type.GetType("Test2.Reflect.Operate"); //PropertyInfo propertyInfo = type.GetProperty("Val"); //propertyInfo.SetValue(obj1, 1, null); //为属性赋值 //Object ret = propertyInfo.GetValue(obj1, null);//获取属性的值 //索引器 //Assembly assembly = Assembly.Load("Test2"); //Object obj1 = assembly.CreateInstance("Test2.Reflect.Operate", false); //Type type = Type.GetType("Test2.Reflect.Operate"); //PropertyInfo propertyInfo = type.GetProperty("Item"); //Object ret = propertyInfo.GetValue(obj1,new Object[]{2}); //获取索引器的值 //propertyInfo.SetValue(obj1, 1,new Object[]{6}); //为索引器赋值 //ret = propertyInfo.GetValue(obj1, new Object[] { 6 }); //获取索引器的值 //访问静态方法 //Assembly assembly = Assembly.Load("Test2"); //Type t = assembly.GetType("Test2.Reflect.Operate"); //MethodInfo met = t.GetMethod("ExcStaticMethod", new Type[] { typeof(string) }); //Object ret = met.Invoke(null, new Object[] { "参数" }); //Type t = Type.GetType("Test2.Reflect.Operate");//如果在同一个项目中或已经添加引用 //MethodInfo met = t.GetMethod("ExcStaticMethod", new Type[] { typeof(string) }); //Object ret = met.Invoke(null, new Object[] { "传递的参数" }); //访问方法 //Assembly assembly = Assembly.Load("Test2"); //Object obj1 = assembly.CreateInstance("Test2.Reflect.Operate", false); //Type t = assembly.GetType("Test2.Reflect.Operate"); //MethodInfo met = t.GetMethod("ExcMethod", new Type[] {typeof(string) }); //Object ret = met.Invoke(obj1, new Object[] {"参数" }); //事件 //Assembly assemblytemp = Assembly.Load("Test2"); //Object objtemp = assemblytemp.CreateInstance("Test2.Reflect.Operate", false); //Type te = Type.GetType("Test2.Reflect.Operate"); //EventInfo evnetInfo = te.GetEvent("hander"); EventHandler eh = new EventHandler(delegate(Object obj,EventArgs e) { Console.WriteLine("LLLLLLL"); }); //EventHandler eh = new EventHandler(delegate { Console.WriteLine("LLLLLLL"); }); //evnetInfo.AddEventHandler(objtemp, eh); //MethodInfo met = te.GetMethod("ExcEvent", new Type[] { }); //Object ret = met.Invoke(objtemp, new Object[] { });
