本文参考

1.本文背景

系列文章最后一篇，一个完整的聊天界面。当然只看效果，具体的项目需要将左侧好友列表、中间会话列表、右侧联系人简况做成MVVM绑定的形式，做成模板才是一个完整的项目，本系列只是对界面的一个设计参考。

前面两篇文章：

C# WPF联系人列表（1/3）
C# WPF简况（2/3）

三篇文章最终效果如下：
技术图片

2.代码实现

使用 .Net CORE 3.1 创建名为 “Chat” 的WPF项目，添加 MaterialDesignThemes(3.0.1)、MaterialDesignColors(1.2.2)两个Nuget库，文中图片已全部替换为站长网站logo图片外链，直接Copy文中代码即可运行，大家亦可下载原作者源码研究学习，文末会给出源码下载链接。

2.1 引入MD控件样式文件

使用MD控件的常规操作，需要在App.xaml中引入4个样式文件：

Application x:Class="Chat.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">

Application.Resources> ResourceDictionary> ResourceDictionary.MergedDictionaries> ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Dark.xaml" /> ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" /> ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Green.xaml" /> ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" /> ResourceDictionary.MergedDictionaries> ResourceDictionary> Application.Resources> Application>

2.2 界面布局

纯粹的布局代码：整个界面分为左、中、右三块，即好友列表、好友会话、好友简况三部分，实际项目，需要将三块做成模板进行MVVM绑定开发，方便扩展。

Window x:Class="Chat.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"

        StackPanel>

2.2.3 窗体部分事件处理

后台代码

private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    DragMove();
}

private void Close_Click(object sender, RoutedEventArgs e)
{
    this.Close();
}

2.2.4 新增两个用户控件

用于展示接收的会话和发送的会话，真实的项目可以做成一个，做成模板。

接收的会话用户控件：

UserControl x:Class="Chat.UserControlMessageReceived"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:Chat"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    Grid>
        Border Background="{StaticResource PrimaryHueDarkBrush}" CornerRadius="15 15 15 0" Margin="10 12">
            TextBlock Margin="15" TextWrapping="Wrap" 
                       Text="你好，怎么联系你？" Foreground="White"/>
        Border>
        TextBlock Text="星期四下午5:45" HorizontalAlignment="Right" VerticalAlignment="Bottom" FontSize="10" Margin="10 -2"/>
    Grid>
UserControl>

发送的会话用户控件：

UserControl x:Class="Chat.UserControlMessageSent"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:Chat"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    Grid>
        Border Background="Gray" CornerRadius="15 15 0 15" Margin="10 12">
            TextBlock Margin="15" TextWrapping="Wrap" Text="微信公众号：Dotnet9，网站：https://dotnet9.com" Foreground="White"/>
        Border>
        TextBlock Text="星期四下午5:55" HorizontalAlignment="Right" VerticalAlignment="Bottom" FontSize="10" Margin="10 -2"/>
    Grid>
UserControl>
