BindingFlags.Instance);
Console.WriteLine ("//Constructors");
PrintMembers (ci);
}
public static void PrintMembers(MemberInfo [] ms) {
foreach (MemberInfo m in ms) {
Console.WriteLine ("{0}{1}", " ", m);
}
Console.WriteLine();
}
}
MemberInfo、MethodInfo、FieldInfo 和 PropertyInfo
使用 MemberInfo、MethodInfo、FieldInfo 或 PropertyInfo 对象可获取有关类型的方法、属性、事件、字段的信息。
以下代码示例使用 MemberInfo 来列出 System.IO.File 类中的成员数量并使用 System.Type.IsPublic 属性来确定该类的可见性。[C#]
using System;
using System.IO;
using System.Reflection;
class Mymemberinfo
{
public static void Main(string[] args)
{
Console.WriteLine ("\nReflection.MemberInfo");
// Get the Type and MemberInfo.
Type MyType =Type.GetType("System.IO.File");
MemberInfo[] Mymemberinfoarray = MyType.GetMembers();
// Get and display the DeclaringType method.
Console.WriteLine("\nThere are {0} members in {1}.",
Mymemberinfoarray.Length, MyType.FullName);
Console.WriteLine("{0}.", MyType.FullName);
if (MyType.IsPublic)
{
Console.WriteLine("{0} is public.", MyType.FullName);
}
}
}
以下代码示例调查指定成员的类型。它对 MemberInfo 类的一个成员执行反射，然后列出其类型。[C#]
// This code displays information about the GetValue method of FieldInfo.
using System;
using System.Reflection;
class MyMethodInfo {
public static int Main() {
Console.WriteLine("Reflection.MethodInfo");
// Get and display the Type.
Type MyType = Type.GetType("System.Reflection.FieldInfo");
// Specify the member for which you want type information here.
MethodInfo Mymethodinfo = MyType.GetMethod("GetValue");
Console.WriteLine(MyType.FullName + "." + Mymethodinfo.Name);
// Get and display the MemberType property.
MemberTypes Mymembertypes = Mymethodinfo.MemberType;
if (MemberTypes.Constructor == Mymembertypes) {
Console.WriteLine("MemberType is of type All");
}
else if (MemberTypes.Custom == Mymembertypes) {
Console.WriteLine("MemberType is of type Custom");
}
else if (MemberTypes.Event == Mymembertypes) {
Console.WriteLine("MemberType is of type Event");
}
else if (MemberTypes.Field == Mymembertypes) {
Console.WriteLine("MemberType is of type Field");
}
else if (MemberTypes.Method == Mymembertypes) {
Console.WriteLine("MemberType is of type Method");
}
else if (MemberTypes.Property == Mymembertypes) {
Console.WriteLine("MemberType is of type Property");
}
else if (MemberTypes.TypeInfo == Mymembertypes) {
Console.WriteLine("MemberType is of type TypeInfo");
}
return 0;
}
}
以下示例代码使用所有的反射 *Info 类以及 BindingFlags 来列出指定类的所有成员（构造函数、字段、属性、事件和方法），并将这些成员划分为静态和实例类别。[C#]
// This program lists all the members of the
// System.IO.BufferedStream class.
using System;
using System.IO;
using System.Reflection;
class ListMembers {
public static void Main(String[] args) {
// Specify the class here.
Type t = typeof (System.IO.BufferedStream);
Console.WriteLine ("Listing all the members (public and non public) of the {0} type", t);
// Static Fields are listed first.
FieldInfo [] fi = t.GetFields (BindingFlags.Static
