在C＃中使用模型视图展示器

问题描述

我是模特 - 视图 - 演示者模式的初学者，我只是想在一个示例项目中使用它进行研究。



让我们在我的项目中说（ac #win forms app）有一个`Employee Class`，它有`EmployeeID`，`Name`，`Address`，`Designation`等属性。它还有`viewEmployee（）`，`AddNewEmployee（）等行为。 ，`PromoteEmployee（）`等



1.你能否告诉我这些东西是如何以MVP模式组织的？



2.我的项目中有几个实体类，如Employee，Client，Attendance，Salary等。那么我应该为每个实体课程分别创建一个DataService和Presenter课程吗？





我目前的理解是这样的...



**实施ViewEmployee（）--- ------- **

Im a beginner to Model-View-Presenter pattern and Im just trying to use it in a sample project for studies.

Lets say in my project (a c# win forms app) there is a `Employee Class` and it has properties like `EmployeeID`,`Name`, `Address`, `Designation` etc. Also it has behaviors like `viewEmployee()`, `AddNewEmployee()`, `PromoteEmployee()` etc.

1. Could you please advice me how these things are organized in MVP pattern?

2. I have several entity classes in my project like Employee, Client, Attendance, Salary etc. So should I make separate DataService and Presenter classes for each one?


My current understanding is like this...

**Implementing ViewEmployee()----------**

Class Employee
    {
        public string EmployeeID { get; set; }
        public string Name { get; set; }
        public string Address { get; set; }
        public string Designation { get; set; }
    }

    Class EmployeePresenter
    {
       public void ViewEmployee(string employeeID, frmEmployeeDetails _form)
       {
         Employee Emp= EmloyeeDataService.GetEmployeeData(employeeID);
         _form.txtName=Emp.Name;
         _form.txtAddress=Emp.Address;
         _form.txtDesignation=Emp.Designation;
       }
    }

    Class EmployeeDataService
    {
        public static Employee GetEmployeeData(String employeeID)
        {
          //Get data from database
          // Set Properties of Employee
          //Return Employee
        }
    }

    Partial Class frmEmployeeDetails : Form
    {
        btnViewEmployee_Click() //Button Event
        {
          EmployeePresenter.ViewEmployee(txtEmployeeID.text,this);
        }
    }
