C#反射获取 所有字段 及 私有字段
using System; using System.Collections.Generic; using System.Text; using System.Reflection; namespace ReflectionDemo { class Program { static void Main(string[] args) { Type t = typeof(ChangeValue); Type[] types = new Type[0];//为构造函数准备参数类型 ConstructorInfo ci = t.GetConstructor(types); //获得构造函数 object[] objs = new object[0];//为构造函数准备参数值 object obj = ci.Invoke(objs);//调用构造函数创建对象 MethodInfo mi = t.GetMethod("WriteLine");//获得公有的writeline方法 mi.Invoke(obj, null); FieldInfo fi = t.GetField("myValue", BindingFlags.NonPublic | BindingFlags.Instance);//获得私有字段 FieldInfo[] fis=t.GetFields(BindingFlags.NonPublic | BindingFlags.Instance|BindingFlags.Public); Console.WriteLine(fis.Length); foreach (var fieldInfo in fis) { Console.WriteLine( fieldInfo.FieldType+":"+ fieldInfo.Name + ":" + fieldInfo.GetValue(obj) ); } fi.SetValue(obj, "new Value"); //改写私有字段 mi.Invoke(obj, null); MethodInfo mi2 = t.GetMethod("Write", BindingFlags.NonPublic | BindingFlags.Instance);//获得私有的Write方法 mi2.Invoke(obj, null); Console.ReadLine(); } } public class ChangeValue { private string myValue = "old Value"; public string firstValue = "values1"; public void WriteLine() { Console.WriteLine("MyValue is: " + myValue); } private void Write() { Console.WriteLine("MyValue is: " + myValue); } } }
