使用Direct协议v4.00时的IPv6处理

Question

我今天尝试打开Direct协议v4.00，但是我遇到了IP地址处理的障碍。一些客户端IP地址是IPv6地址，例如：<Window x:Class="ButtonContentExample.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:ButtonContentExample" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> <Window.DataContext> <local:ExampleViewModel /> </Window.DataContext> <StackPanel> <TextBlock Text="{Binding TestResult}" Margin="12" FontSize="20" /> <ListBox ItemsSource="{Binding Items}"> <ItemsControl.ItemTemplate> <DataTemplate DataType="{x:Type local:TestItemViewModel}"> <Button Content="{Binding Value}" Command="{Binding TestCommand}" CommandParameter="{Binding Content, RelativeSource={RelativeSource Mode=Self}}" Width="50"/> </DataTemplate> </ItemsControl.ItemTemplate> </ListBox> </StackPanel> （我对该地址进行了一些调整）

当我通过发送这些IPv6地址时，出现以下错误：

using System;
using System.Collections.ObjectModel;
using System.ComponentModel;
using System.Runtime.CompilerServices;
using System.Windows.Input;

namespace ButtonContentExample
{
    public class RelayCommand : ICommand
    {
        public event EventHandler CanExecuteChanged;
        public RelayCommand(Action<object> execute) : this(execute, null) { }
        public RelayCommand(Action<object> execute, Predicate<object> canExecute)
        {
            ExecuteAction = execute;
            CanExecutePredicate = canExecute ?? new Predicate<object>(obj => true);
        }
        public Action<object> ExecuteAction { get; }
        public Predicate<object> CanExecutePredicate { get; }
        public bool CanExecute(object parameter) => CanExecutePredicate(parameter);
        public void Execute(object parameter) => ExecuteAction(parameter);
    }

    public abstract class ViewModelBase : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;
        public void Notify<T>(ref T t, T value, [CallerMemberName] string name = "")
        {
            t = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
        }
    }

    public class ExampleViewModel : ViewModelBase
    {
        private string testResult;
        private ObservableCollection<TestItemViewModel> items = new ObservableCollection<TestItemViewModel>();
        public ExampleViewModel()
        {
            for (var i = 0; i < 50; i++) Items.Add(new TestItemViewModel(this) { Value = i });
        }
        public ObservableCollection<TestItemViewModel> Items
        {
            get => items;
            set => Notify(ref items, value);
        }

        public string TestResult
        {
            get => testResult;
            set => Notify(ref testResult, value);
        }
    }

    public class TestItemViewModel : ViewModelBase
    {
        private int value;
        private string result;
        public TestItemViewModel(ExampleViewModel parent)
        {
            Parent = parent;
            TestCommand = new RelayCommand(obj => Result = obj.ToString());
        }
        public int Value
        {
            get => value;
            set => Notify(ref this.value, value);
        }

        public string Result
        {
            get { return result; }
            set
            {
                Notify(ref result, value);
                Parent.TestResult = value;
            }
        }

        public RelayCommand TestCommand { get; }
        public ExampleViewModel Parent { get; }
    }
}

如果我完全省略了IP地址，则会出现以下错误：

2a02:c7f:d192:dc00:de4:a84d:aab5:8225

那么，当我收到一个IPv6地址时我打算做什么？退回直接协议v3.00？
