net技术中"反射"的使用方法

本文主要介绍net技术中"反射"的使用方法,包括如何对属性赋值,获取变量,属性,方法,事件的列表,如何设置属性及调用方法等.希望对新人有所帮助咯.

 //反射的使用方法public class TestProperty{ private int i_seqnum = 0; private string s_authorid = string.Empty; public int SeqNum { get { return i_seqnum; } set { i_seqnum = value; } } public string AuthorID { get { return s_authorid; } set { s_authorid = value; } } public TestProperty() { } public TestProperty(string as_authorid) { this.AuthorID = as_authorid; } public void GetAuthorID() { if (s_authorid == "" || s_authorid == string.Empty) { System.Console.WriteLine("Null"); } else { System.Console.WriteLine(s_authorid); } }} //调用方式TestProperty test = new TestProperty();Type t = test.GetType(); //列出类型的结构信息System.Console.WriteLine("列出类型的结构信息");ConstructorInfo[] test_constructor = t.GetConstructors();foreach (ConstructorInfo item_constructor in test_constructor){ System.Console.WriteLine(item_constructor.Name);} //列出TestProperty类中所有变量System.Console.WriteLine("列出TestProperty类中所有变量");FieldInfo[] test_field = t.GetFields();foreach (FieldInfo item_field in test_field){ System.Console.WriteLine(item_field.Name);} //列出TestProperty类中所有属性System.Console.WriteLine("列出TestProperty类中所有属性");PropertyInfo[] list_property = t.GetProperties();foreach (PropertyInfo item_property in list_property){ System.Console.WriteLine(item_property.Name);} //列出TestProperty类中所有方法System.Console.WriteLine("列出TestProperty类中所有方法");MethodInfo[] test_method = t.GetMethods();foreach (MethodInfo item_method in test_method){ System.Console.WriteLine(item_method.Name);}//列出TestProperty类中所有事件System.Console.WriteLine("列出TestProperty类中所有事件");EventInfo[] test_event = t.GetEvents();foreach (EventInfo item_event in test_event){ System.Console.WriteLine(item_event.Name);}//赋值t.GetProperty("SeqNum").SetValue(test, 1, null);t.GetProperty("AuthorID").SetValue(test, "ADB01", null);//取值int i_seqnum = Convert.ToInt32(t.GetProperty("SeqNum").GetValue(test, null));string s_authorid = t.GetProperty("AuthorID").GetValue(test, null).ToString(); //使用反射调用方法//test.GetAuthorID();System.Console.WriteLine("使用反射调用方法");string[] s = { "BC001" };MethodInfo method_getauthorid = t.GetMethod("GetAuthorID");//第1种方法object obj_name = Activator.CreateInstance(t, s);method_getauthorid.Invoke(obj_name, null);//第2种方法object obj = Activator.CreateInstance(t);method_getauthorid.Invoke(obj, null);
