博客围绕应用程序信息收集展开，指出常规信息收集操作重复且代码僵化。作者思考通用处理方式，定义公共数据接口，让数据实体类实现该接口，还给出示例代码。经测试，程序运行良好，解决了数据收集重复操作问题，后续将解决界面控件自动生成问题。
关键字：Grove 、Reflection、UI
在编写应用程序时，我们都需要收集一些必备的数据。比如我们举一个常见的例子，员工和客户在许多应用程序中我们都会遇到(如图1)。每次遇上我们不外是先画一个窗体,然后在窗体上放置不同的控件用于收集信息。

对于上面的这些信息收集，其操作过程完全是一样的。保存时，先对界面控件的值进行判断是否有效,后一一收集，然后保存。新增时，先判断单据是否修改过，如修改，则提醒用户是否保存。最后将界面控件的值设置为初始值。显示一条记录时，我们做的是从数据库中取出一条记录（有可能是实体对象），然后将记录中的数据一一设置到对应的控件上。
这就是我们平常的自以为的”高新技术”,经过N+1次机械的“编程”后，我已经厌恶了这种到处充斥着缰化和腐朽思想的代码。我思考着一种能解决所有界面录入问题的方式(复杂界面暂不考察)。我们已知道这些不同信息收集界面的处理方式都是相同的，唯一不同的只是存放在数据库不同的表中，以及表的字段及数据类型等不同。OK，既然处理方式相同，那么对于实现一种通用处理方式是可能的。下面请花点时间来整理一下我们的思路。
所有的处理方式相同，意味着我们可以定义一个公共的数据接口，所有需要收集信息的表，通常我们都会做ORM。如果这一步做了，那么请等一下，请让数据实体类实现我们定义的接口吧。
using System;
namespace JadeSoft.Common

}
在IEntity此接口中我们定义了OID此字段，毫无疑问，这意味着所有的数据库表中的主键都设置为OID，还是uniqueidentifier型的.下面来看一下我定义的实体类(//此处使用了Grove组件。它可以帮我动态解决数据持久问题.如有不明请http://grove.91link.com下载并运行,这里不多作解释)

几乎在数据实体类的每个属性 (Property) 上，我都加入了[EntityUIControl("txtDeptCode")]，这样一句属性（Attribute）修饰。其实正是Grove的使用给我了一定的启发，利用Attribute来传递一些运行时数据。 EntityUIControl类派生自System.Attribute.主要功能是用来描述某个Property 在界面上对应哪个控件的哪个属性（显示或收集数据时用）。我在定义EntityUIControl允许用户设置对应界面控件的ID及数据绑定属性，默认为Text属性，如用户特殊要求，可自行再设置（[EntityUIControl("dtEditTime","DateTime")]）
好，接下来我们看一下EntityUIControl是如何实现的。还是来用代码来说话吧。
namespace JadeSoft.Common
{
/// <summary>
/// 用于标记实体对象的属性对应于界面哪个控件
/// </summary>
[AttributeUsageAttribute(AttributeTargets.Property)]
public class EntityUIControl:System.Attribute
{
string cID;//控件ID
public string ControlID
{
get{return cID;}
set{cID=value;}
}
//默认为TEXT属性
string _ControlPropery="Text";
/// <summary>
/// 要将实体的值显示到控件的哪个属性
/// </summary>
public string DisplayPropery
{
get
{
return _ControlPropery;
}
set
{
_ControlPropery=value;
}
}
/// <summary>
/// 界面控件的类型及实体对象的属性的对应关系处理
/// </summary>
/// <param name="ControlID">控件ID</param>
public EntityUIControl(string ControlID)
{
cID=ControlID;
}
public EntityUIControl(string ControlID,string ControlPropery)
{
cID=ControlID;
_ControlPropery=ControlPropery;
}
}
}
既然前提都准备好了，那么我考虑这样一种方案。我定义一个基窗体类(FrmAddBase)。此类将负责所有信息的数据保存，及数据显示等业务，因为我们前面讲过这些业务规则的处理都是一样的。那么数据验证呢，好象每个数据收集窗体的验证规则都不一样，那么好，只能让派生类自己处理了。基类如下图，只有一个工具栏，上面有保存，新增这二个功能（示例用）,我们上面看到的图1，其实都是派生自此类

有很多个数据收集窗体的业务处理都在FrmAddBase里实现。这可能吗？请不要怀疑，很早以前我也是怀疑这个问题，因此我没有去尝试去解决。其实只要你愿去尝试一些看起来不可能解决的问题，那么问题的解决其实只差一步之遥了。在看我们剩下来的一步时我要申明一点是对于运行效率非常讲究的程序员我不建议阅读! 因为下面的思路是建立在灵活换取效率的基础上的。
如何解决不同的自定义实体类的保存及界面显示，看似一个很复杂的问题。那么多不同的数据实体的属性，如何区分，如何映射到数据库，及如何动态生成SQL语句。为什么我们不能使用反射来解决这个问题，利用System.Reflection我们可以实现对元数据的访问，同样我们也可以使用它来动态的创建对象。我们完全可以在FrmAddBase中对所引用的数据实体进行反射，查看数据实体对象的元数据，从而解决将数据实体的属性值显示在界面上或将界面的值保存到数据实体对象中去，那样的话，以前那种 Emp.EmpName=txtEmp.Text;或txtEmp.Text=Emp.EmpName这种腐朽的代码可以从我们的程序中一扫而光了。

EntityController 类，此类主要功能是在运行时，根据传入的对象，利用反射功能来将对象的值设置到界面元素，或将界面元素的值设置到实体对象。同时可以判断对象的值与界面元素是否一致等。从而统一解决了不同实体对象的录入设置问题。
大致问题都差不多，那么我们可以来看一下，界面FrmAddBase及其子类（不同数据收集窗体）是如何工作的。

对于信息收集子窗体来说，做的事情就很简单了，只是做一些数据验证，然后提供了父类对数据保存前及保存后对子类函数的调用。以方便子类进行一些自定义操作。
此程序经过实际测试，运行良好，对于性能的损失也不是很大。同时解决了所有数据收集的重复操作过程。 以上代码只是初次实验代码。未经过优化。此次演示时，派生窗体的控件是事先构建好的，下次将注重解决界面控件自动生成问题。
