在WinForm开发中，我们是不是为绑定界面控件的数据而每个控件每个控件的赋值？在保存修改时是不是也是每个控件每个控件的赋值到实体中？字段一多，那简直就是噩梦。有没有像Web中那样方便的方法直接就自动映射了呢？现在不用如此繁琐，在RDIFramework.NET开发框架的WinForm部分新增了界面控件到实体，实体到界面控件自动绑定，一句话就搞定了，非常的方便。主要是引用“RDIFramework.WinForm.Utilities.dll”dll文件，再调用下面两个方法即可：
1、实体到界面控件的自动映射：FormBinding.BindObjectToControls(TestEntity, this);
2、界面控件到实体的自动映射：FormBinding.BindControlsToObject(TestEntity, this);
效果如下图所示：
下面给出上面的测试界面的全部代码供大家参考：
