1.本文背景

聊天軟體大家用的比較多，用WPF做個聯繫人列表試試

本文效果如下：

2.代碼實現

使用 .Net CORE 3.1 創建名為 “Chat” 的WPF項目，添加 MaterialDesignThemes(3.0.1)、MaterialDesignColors(1.2.2)兩個Nuget庫，文中部分圖片可在文末視頻配套源碼中下載。

2.1 引入MD控制項樣式文件

使用MD控制項的常規操作，需要在App.xaml中引入4個樣式文件

<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 界面佈局

純粹的佈局代碼：

<Window x:Class="Chat.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        Height="600" Width="1080" ResizeMode="NoResize" MouseLeftButtonDown="Window_MouseLeftButtonDown"
        WindowStartupLocation="CenterScreen" WindowStyle="None">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="270"/>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="270"/>
        </Grid.ColumnDefinitions>

        <Grid Grid.Column="1" Background="#FFE4E4E4"/>

        <StackPanel Grid.Column="0" Background="{StaticResource PrimaryHueDarkBrush}">
            <StackPanel Orientation="Horizontal" Background="White">
                <Image Width="210" Height="80" Source="Assets/logo.png"/>
                <Button Style="{StaticResource MaterialDesignFlatButton}">
                    <materialDesign:PackIcon Kind="PlusCircle" Width="24" Height="24"/>
                </Button>
            </StackPanel>
            <TextBox Margin="20 10" Style="{StaticResource MaterialDesignFloatingHintTextBox}" materialDesign:HintAssist.Hint="搜索" Foreground="White"/>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>

                <Button Style="{StaticResource MaterialDesignFlatButton}" Grid.Column="0">
                    <materialDesign:PackIcon Kind="History" Foreground="White"/>
                </Button>
                <Button Style="{StaticResource MaterialDesignFlatButton}" Grid.Column="1">
                    <materialDesign:PackIcon Kind="People" Foreground="White"/>
                </Button>
                <Button Style="{StaticResource MaterialDesignFlatButton}" Grid.Column="2">

                </Button>
                <Button Style="{StaticResource MaterialDesignFlatButton}" Grid.Column="3">
                    <materialDesign:PackIcon Kind="Archive" Foreground="White"/>
                </Button>
            </Grid>
            <ListView>
                <ListViewItem HorizontalAlignment="Stretch">
                    <Grid HorizontalAlignment="Center" Margin="5">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="50"/>
                            <ColumnDefinition Width="150"/>
                            <ColumnDefinition Width="50*"/>
                        </Grid.ColumnDefinitions>

                        <Border Width="40" Height="40" CornerRadius="25" BorderBrush="White" BorderThickness="0.6">
                            <Border.Background>
                                <ImageBrush ImageSource="https://img.dotnet9.com/logo.png"/>
                            </Border.Background>
                        </Border>
                        <Border Width="10" Height="10" VerticalAlignment="Bottom" Margin="5" HorizontalAlignment="Right" CornerRadius="15" Background="LightGreen"/>

                        <StackPanel Grid.Column="1">
                            <TextBlock Text="Dotnet9.com" Margin="10 0"/>

                        </Border>
                    </Grid>
                </ListViewItem>
            </ListView>
        </StackPanel>

    </Grid>
</Window>

2.2.3 窗體拖動

後臺代碼

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