使用C#进行Reflection编程

using System;
using System.Reflection;
using System.Reflection.Emit;
public class TestReflection
{
private String file = @"TestReflection.exe";
static void Main(String[] args)
{
TestReflection test = new TestReflection();
test.DisplayModules();
test.DisplayTypes();
test.DisplayMethods();
test.InvokeStaticMethod();
test.InvokeMethod();
}
//显示所有模块名
public void DisplayModules()
{
Console.WriteLine("display modules ...");
Assembly assembly = Assembly.LoadFrom(file);
Module[] modules = assembly.GetModules();
foreach (Module module in modules)
{
Console.WriteLine("module name:" + module.Name);
}
}
//显示所有类型名
public void DisplayTypes()
{
Console.WriteLine("display types ...");
Assembly assembly = Assembly.LoadFrom(file);
Type[] types = assembly.GetTypes();
foreach (Type type in types)
{
Console.WriteLine("type name:" + type.FullName);
}
}
//先是一个类型中的所有方法名
public void DisplayMethods()
{
Console.WriteLine("display methods in TestReflection Type ...");
Assembly assembly = Assembly.LoadFrom(file);
Type type = assembly.GetType("TestReflection");
MethodInfo[] methods = type.GetMethods();
foreach (MethodInfo method in methods)
{
Console.WriteLine("method name:" + method.Name);
}
}
//调用一个类中的静态方法
public void InvokeStaticMethod()
{
Console.WriteLine("Invoke static method ...");
Assembly assembly = Assembly.LoadFrom(file);
Type type = assembly.GetType("TestSubClass");
type.InvokeMember("SayHello", BindingFlags.InvokeMethod, null, null, new object[] { });
}
//调用一个类中的非静态方法
