反射是描述代码中类型，方法和字段的元数据的过程。命名空间System.Reflection使您能够获取有关已加载程序集及其中的元素（如类，方法和值类型）的数据。System.Reflection有许多类，但最常用的是Assembly，AssemblyName，ConstructorInfo，MethodInfo，ParameterInfo，EventInfo，PropertyInfo和MemberInfo。
static void Main(string[] args){
TypeInfo myType = typeof(TextInfo).GetTypeInfo();
IEnumerable<PropertyInfo> properties = myType.DeclaredProperties;
IEnumerable<MethodInfo> methods = myType.DeclaredMethods;
Console.WriteLine(myType);
Console.WriteLine(properties);
Console.WriteLine(methods);
StringBuilder strBuilder = new StringBuilder();
Console.WriteLine();
strBuilder.Append("这些属性是：");
foreach (PropertyInfo p in properties){
strBuilder.Append("\n" + p.Name);
}
strBuilder.Append("\n");
strBuilder.Append("\nThe methods are:");
foreach (MethodInfo m in methods){
strBuilder.Append("\n" + m.Name);
}
Console.WriteLine(strBuilder);
}输出结果
