1、演示 socket tcp 的应用（本例既做服务端又做客户端）
Communication/SocketDemo.xaml
<phone:PhoneApplicationPage x:Class="Demo.Communication.SocketDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" FontFamily="{StaticResource PhoneFontFamilyNormal}" FontSize="{StaticResource PhoneFontSizeNormal}" Foreground="{StaticResource PhoneForegroundBrush}" SupportedOrientations="Portrait" Orientation="Portrait" mc:Ignorable="d" shell:SystemTray.IsVisible="True"> <Grid Background="Transparent"> <StackPanel Orientation="Vertical"> <StackPanel> <Button Name="btnStartListener" Content="start a socket listener" Click="btnStartListener_Click" /> <Button Name="btnConnectListener" Content="connect to the socket listener" Click="btnConnectListener_Click" Margin="0 10 0 0" /> <Button Name="btnSendData" Content="send data" Click="btnSendData_Click" Margin="0 10 0 0" /> <Button Name="btnCloseSocket" Content="close server socket and client socket" Click="btnCloseSocket_Click" Margin="0 10 0 0" /> </StackPanel> <TextBlock Name="lblMsg" TextWrapping="Wrap" Margin="20 0 0 0" /> </StackPanel> </Grid> </phone:PhoneApplicationPage>
