Question

我的WPF窗口中的第二个窗口为空白。

我尝试在多个位置声明变量，并与声明分开分配new Send()的值。

我还确保它不只是我的计算机。我将编译后的程序发送给其他人，并且做同样的事情。

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            Send send = new Send();
            send.Show();
        }

发送类：

    public partial class Send : Window
    {
        public Send()
        {
            InitializeComponent();
            ipIdBox.Text = GenerateIPID(GetIPAddress(), 8000);
        }

        private string GetIPAddress()
        {
            var host = Dns.GetHostEntry(Dns.GetHostName());
            foreach (var ip in host.AddressList)
            {
                if (ip.AddressFamily == AddressFamily.InterNetwork)
                {
                    return ip.ToString();
                }
            }
            throw new Exception("No network adapters with an IPv4 address in the system!");
        }

        private string GenerateIPID(string ip, int port)
        {
            string[] ipseps = ip.Split('.'); // Split IP into parts
            string code = ""; // Initialize the code
            int counter = 0; // A counter (because every 4 digits are seperated)
            foreach (string ippart in ipseps)
            {
                int ipparti = Convert.ToInt32(ippart);
                string hippart = ipparti.ToString("X2");
                code += hippart;
                counter++;
                if (counter == 1) {
                    counter = 0;
                    code += "-";
                }
            }
            code += $"-{port.ToString("X4")}";
            return code;
        }

    }

...这是XAML

<Window x:Class="ScistMain.Send"
        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:ScistMain"
        mc:Ignorable="d"
        Title="Send" Height="264.95" Width="451.774" OverridesDefaultStyle="True" Topmost="True">
    <Grid>
        <TextBlock x:Name="ipIdBox" Margin="0,124,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Height="34" TextAlignment="Center" FontSize="24" Text="7F00-0001-8000"/>
        <TextBlock Margin="0,108,0,0" TextWrapping="Wrap" Text="Tell the person recieving to type this code:" VerticalAlignment="Top" Width="444" TextAlignment="Center"/>
        <TextBlock Margin="0,10,0,0" TextWrapping="Wrap" Text="You are sending:" VerticalAlignment="Top" TextAlignment="Center" FontSize="18" FontWeight="Bold"/>
        <Image x:Name="iconImg" Height="32" Margin="206,39,206,0" VerticalAlignment="Top" Width="32" Source="Resources/scist.ico"/>
        <TextBlock Margin="0,76,0,0" TextWrapping="Wrap" Text="Placeholder Program" VerticalAlignment="Top" TextAlignment="Center"/>
        <ProgressBar x:Name="pBar" HorizontalAlignment="Left" Height="34" Margin="10,124,0,0" VerticalAlignment="Top" Width="424" Visibility="Collapsed"/>
        <Button Content="Cancel" HorizontalAlignment="Left" Margin="359,203,0,0" VerticalAlignment="Top" Width="75"/>

    </Grid>
</Window>

我希望它显示我在设计器中创建的窗口：

但它显示一个黑色窗口。
