推荐答案

听起来像您并不完全了解分层体系结构的工作原理.

对于三层体系结构:
有一个UI层
创建一个类库-BusinessLogic
创建一个类库-DataAccess

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3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 [

Sounds like you are not totally aware of how a layered architecture works.

For 3-tier architecture:
Have a UI layer
Create a class library - BusinessLogic
Create a class library - DataAccess

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.
Have a look at these, explaination with samples:
3-tier architecture in C#[^]
3-Tier Architecture Examples[^]
3-Tier Architecture in ASP.NET with C#[^]

For uploading, you will upload file from UI only... pass it to DB using BL.
