Type InvokeMember()用法简介
主要以下面 代码做分析
举例： Type tDate = typeof(System.DateTime); Object result = tDate.InvokeMember("Now", BindingFlags.GetProperty, null, null, new Object[0]); Console.WriteLine(result.ToString()); 例2： /*注意：下面备注的方法都是其他类的方法，比如：TestClass类方法*/ TestClass tc = new TestClass (); //AddUp为tc的方法 tc.GetType().InvokeMember ("AddUp", BindingFlags.Public | BindingFlags.Instance | BindingFlags.CreateInstance, null, tc, new object [] {}); /* public void AddUp () { methodCalled++; Console.WriteLine ("AddUp Called {0} times", methodCalled); } */ //----------------------------下面传参数 执行ComputeSum方法 带有两个参数 Type t = typeof (TestClass); object [] args = new object [] {100.09, 184.45}; object result = t.InvokeMember ("ComputeSum", BindingFlags.InvokeMethod, null, null, args); /* public static double ComputeSum (double d1, double d2) { return d1 + d2; } */ //-----------SayHello为静态方法调用 t.InvokeMember ("SayHello", BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Static, null, null, new object [] {}); //-----------实例方法调用 TestClass c = new TestClass (); c.GetType().InvokeMember ("AddUp", BindingFlags.InvokeMethod, null, c, new object [] {}); c.GetType().InvokeMember ("AddUp", BindingFlags.Public | BindingFlags.Instance | BindingFlags.CreateInstance, null, c, new object [] {}); //----------获取字段 result = t.InvokeMember ("Name", BindingFlags.GetField | BindingFlags.GetProperty, null, c, new object [] {}); result = t.InvokeMember ("Value", BindingFlags.GetField | BindingFlags.GetProperty, null, c, new object [] {}); /* public String Name; public Object Value { get { return "the value"; } } */ result = t.InvokeMember ("Name", BindingFlags.GetField, null, c, new object [] {}); //---------设置字段 t.InvokeMember ("Name", BindingFlags.SetField, null, c, new object [] {"NewName"}); //NewName设置的属性值 //---------调用类方法 带参数 object[] argValues = new object [] {"Mouse", "Micky"}; String [] argNames = new String [] {"lastName", "firstName"}; t.InvokeMember ("PrintName", BindingFlags.InvokeMethod, null, null, argValues, null, null, argNames); /* public static void PrintName (String firstName, String lastName) { Console.WriteLine ("{0},{1}", lastName,firstName); } */ TestClass obj = new TestClass(); System.Reflection.MethodInfo methInfo = obj.GetType().GetMethod("PrintName"); methInfo.Invoke(obj,BindingFlags.SuppressChangeType | BindingFlags.InvokeMethod, null,new object[] {"Brad","Smith"},null); methInfo = obj.GetType().GetMethod("PrintName"); methInfo.Invoke(obj,BindingFlags.IgnoreCase | //忽略大小写 指定当绑定时不应考虑成员名的大小写 BindingFlags.InvokeMethod, null,new object[] {"brad","smith"},null); methInfo = obj.GetType().GetMethod("PrintName"); methInfo.Invoke(obj,BindingFlags.IgnoreReturn | // 在 COM interop 中用于指定可以忽略成员的返回值 BindingFlags.InvokeMethod, null,new object[] {"Brad","Smith"},null); methInfo = obj.GetType().GetMethod("PrintName"); methInfo.Invoke(obj,BindingFlags.OptionalParamBinding | BindingFlags.InvokeMethod, null,new object[] {"Brad","Smith"},null); // BindingFlags.ExactBinding methInfo = obj.GetType().GetMethod("PrintName"); methInfo.Invoke(obj,BindingFlags.ExactBinding | BindingFlags.InvokeMethod, null,new object[] {"Brad","Smith"},null); // BindingFlags.FlattenHierarchy methInfo = obj.GetType().GetMethod("PrintName"); methInfo.Invoke(obj,BindingFlags.FlattenHierarchy | BindingFlags.InvokeMethod, null,new object[] {"Brad","Smith"},null); //----------调用一个默认的方法 Type t3 = typeof (TestClass2); /* [DefaultMemberAttribute ("PrintTime")] public class TestClass2 { public void PrintTime () { Console.WriteLine (DateTime.Now); } } */ t3.InvokeMember ("", BindingFlags.InvokeMethod | BindingFlags.Default, null, new TestClass2(), new object [] {}); //---------调用一个引用方法 MethodInfo m = t.GetMethod("Swap"); args = new object[2]; args[0] = 1; args[1] = 2; m.Invoke(new TestClass(),args); /* public void Swap(ref int a, ref int b) 交换 a b { int x = a; a = b; b = x; } */
