C# 反射（Reflection）
反射指程序可以访问、检测和修改它本身状态或行为的一种能力。
程序集包含模块，而模块包含类型，类型又包含成员。反射则提供了封装程序集、模块和类型的对象。
您可以使用反射动态地创建类型的实例，将类型绑定到现有对象，或从现有对象中获取类型。然后，可以调用类型的方法或访问其字段和属性。
优缺点
优点：
- 1、反射提高了程序的灵活性和扩展性。
- 2、降低耦合性，提高自适应能力。
- 3、它允许程序创建和控制任何类的对象，无需提前硬编码目标类。
缺点：
- 1、性能问题：使用反射基本上是一种解释操作，用于字段和方法接入时要远慢于直接代码。因此反射机制主要应用在对灵活性和拓展性要求很高的系统框架上，普通程序不建议使用。
- 2、使用反射会模糊程序内部逻辑；程序员希望在源代码中看到程序的逻辑，反射却绕过了源代码的技术，因而会带来维护的问题，反射代码比相应的直接代码更复杂。
以上来自菜鸟教程解释
假如我需要让代码自动识别并执行dll里面所有的方法，这个时候就可以用到c#反射；
1.先用c#写个简单的UI，效果图如下：
代码部分
From1.cs
From1.Designer.cs
//Form1.Designer.cs
namespace BojayUI
{
partial class Form1
{
///
/// Required designer variable.
///
private System.ComponentModel.IContainer components = null;
///
/// Clean up any resources being used.
///
/// true if managed resources should be disposed; otherwise, false.
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code
