WPF+Mvvm项目入门完整教程-仓储管理系统(二)
一、搭建一个主界面框架
主要实现主界面的框架样式和基础功能。这里特别说明一下,由于MvvmLight 已经过时不在维护,本项目决定将MvvmLight框架变更为 CommunityToolkit.Mvvm 框架,使用方法和 MvvmLight 一样,具体配置大家可以参考像 MvvmLight 一样使用 CommunityToolkit.Mvvm 工具包 这篇文章。本节实现效果如下所示:
二、实现步骤
1.主界面区域划分
这里我们分析一下,主界面一共分成上中下三个区域,最上面的为系统功能按钮,中间区域显示内容信息,底部显示系统版本版权信息等。分割效果图如下:
2.主界面区域实现

using CommonProject_DeskTop.ViewModel;
using CommunityToolkit.Mvvm.Messaging;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;

public partial class MainWindow : Window
{

private void RegisterMessage()
{
注册一个系统菜单功能消息
WeakReferenceMessenger.Default.Register<string>(this, HandleMessage);
}
private void HandleMessage(object recipient, string message)
{
switch (message)
{
case "MainWindowClose":

{

if (e.LeftButton == MouseButtonState.Pressed && this.WindowState != WindowState.Maximized)
{

}
}
}
}
