用C-sharpWPF实现连续ARQ协议接收端的实现

以下是使用C-sharp WPF实现连续ARQ协议接收端的示例代码：

1.创建WPF应用程序

2.创建MainWindow.xaml文件并添加以下XAML代码：

<Window x:Class="ARQReceiver.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="ARQReceiver" Height="350" Width="525">
<Grid>
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal" Margin="5">
<TextBlock Text="Sender Address:" Margin="5"/>
<TextBox x:Name="txtSenderAddress" Margin="5"/>
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="5">
<TextBlock Text="Receiver Address:" Margin="5"/>
<TextBox x:Name="txtReceiverAddress" Margin="5"/>
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="5">
<TextBlock Text="Sequence Number:" Margin="5"/>
<TextBox x:Name="txtSeqNum" Margin="5"/>
</StackPanel>
<StackPanel Orientation="Horizontal" Margin="5">
<TextBlock Text="Payload:" Margin="5"/>
<TextBox x:Name="txtPayload" Margin="5"/>
</StackPanel>
<Button x:Name="btnReceive" Content="Receive" Margin="5" Click="btnReceive_Click"/>
<StackPanel Orientation="Horizontal" Margin="5">
<TextBlock Text="Received Data:" Margin="5"/>
<TextBox x:Name="txtReceivedData" Margin="5"/>
</StackPanel>
</StackPanel>
</Grid>
</Window>

3.在MainWindow.xaml.cs文件中添加以下代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;

namespace ARQReceiver
{
public partial class MainWindow : Window
{
private int expectedSeqNum = 0;

public MainWindow()
{
InitializeComponent();
}

private void btnReceive_Click(object sender, RoutedEventArgs e)
{
// Simulate receiving a packet from the sender
int senderAddress = int.Parse(txtSenderAddress.Text);
int receiverAddress = int.Parse(txtReceiverAddress.Text);
int seqNum = int.Parse(txtSeqNum.Text);
string payload = txtPayload.Text;

// Check if the received packet is the expected one
if (seqNum == expectedSeqNum)
{
// Update expected sequence number
expectedSeqNum++;

// Display received data
txtReceivedData.Text += payload + "\r\n";
}
}
}
}

4.在Main方法中启动WPF应用程序：

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;

namespace ARQReceiver
{
/// <summary>
/// Interaction logic for App.xaml
/// </summary>
public partial class App : Application
{
[STAThread]
public static void Main()
{
App app = new App();
app.InitializeComponent();
app.Run(new MainWindow());
}
}
}

5.运行应用程序并输入发送方地址、接收方地址、序列号和有效载荷。单击“接收”按钮，应用程序将模拟接收数据包并显示有效载荷。如果接收到的序列号与预期的序列号匹配，则有效载荷将显示在“Received Data”文本框中。
