1.本文背景

聊天软件大家用的比较多，用wpf做个联系人列表试试

本文效果如下：

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，文中部分图片可在文末视频配套源码中下载。

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：

<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">
                    <materialdesign:packicon kind="contacts" foreground="white"/>
                </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"/>
                            <textblock text="一个热衷于互联网分享精神的程序员的网站!" margin="10 0" texttrimming="characterellipsis" opacity="0.6" fontsize="11"/>
                        </stackpanel>

                        <border grid.column="2" width="20" height="20" cornerradius="15" background="white" horizontalalignment="center" verticalalignment="center" margin="5">
                            <textblock fontsize="11" text="9" foreground="{staticresource primaryhuedarkbrush}" horizontalalignment="center" verticalalignment="center"/>
                        </border>
                    </grid>
                </listviewitem>
            </listview>
        </stackpanel>

    </grid>
</window>

2.2.3 窗体拖动

后台代码

private void window_mouseleftbuttondown(object sender, mousebuttoneventargs e)
{
    dragmove();
}
