推荐答案

创建一个类库-BusinessLogic.在UI层项目中添加它的引用.
创建一个类库-DataAccess.在BL层项目中添加它的引用.

现在，从您的UI，使用对象模型并传递给BusinessLogic项目类.此类是业务逻辑类.在此处根据您的需要进行更改.
现在，将更改后的数据从业务逻辑类传递到dataAccess项目类.在此类中，使用ADO.NET并将所需的值传递给存储过程.

为了获取数据，数据将从DA传输到BL层，然后再从BL传输到UI层.
看看这些，用示例进行解释:
C#中的三层体系结构 [ 3-层架构示例 [使用C#的ASP.NET中的3层体系结构 [

Create a class library - BusinessLogic. Add a reference of it in UI layer project.
Create a class library - DataAccess. Add a reference of it in BL layer project.

Now, from your UI, use the object model and pass on to BusinessLogic project class. This class is a Business logic class. Do the changes as per your need here.
Now, pass on the changed data from business logic class to dataAccess project class. In this class, use ADO.NET and pass on the needed values to Stored Procedure.

For getting back data, it will be transferred from DA to BL and then BL to UI layer.

Try the problem by yourself and post specific issue.

请通过 3层体系结构在ASP.NET中使用C# [ ^ ] .

这正是您所需要的.

Please go through 3-Tier Architecture in ASP.NET with C#[^].

This is exactly what you need.
