C# WPF聊天界面(3/3)

- 本文背景
- 代码实现
- 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:
三篇文章最终效果如下:
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"

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>
