本文档展示了一个WPF应用程序的实现，该程序能够通过IP摄像头DLL库控制摄像头，并使用配置的IP地址、用户名和密码进行连接。同时，程序通过串口通信模块实现了对远程风扇的开关控制，包括打开和关闭风扇的功能。代码中包含了UI设计、事件处理和串口操作的相关细节。

1：添加引用IPCameraDll.dll和System.Configuration,并且把MyCamer.dll复制到bin目录下
在这里插入图片描述
2：在MainWindow.xaml中添加代码

<Window x:Class="Demo10.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="457" Width="750">
    <Grid>
        <Grid.Background>
            <ImageBrush ImageSource="bg_main_menu.png"/>
        </Grid.Background>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="546*"/>
            <ColumnDefinition Width="100*"/>
        </Grid.ColumnDefinitions>
        <Image Grid.Column="0" HorizontalAlignment="Left" Name="img"  Margin="17,17,0,61.722" Width="476.389" Stretch="Fill" Source="NoPic.png"/>
        <Grid Grid.Column="1">
            <Image Grid.Column="0" HorizontalAlignment="Left" x:Name="img1"    Stretch="Fill"/>
            <Button x:Name="btnStart" Content="开始" HorizontalAlignment="Left"  VerticalAlignment="Top" Width="75" Click="btnStart_Click" Tag="0" Margin="10,41,0,0"/>

        </Grid>
    </Grid>
</Window>
