动态更新文本块值

Question

大家好我正在尝试通过 TCP/IP 读取值来动态更新文本块。我做错了什么，我该如何解决？另外，如果有更好的做事方式，我愿意学习。

这里我使用一个public static来在其他类中使用这个类

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

namespace Script_Launcher.Validation
{
    //Global variable to read message elsewhere in the code.
    public class Message
    {
        private static string message = "";

        public static string Messager
        {
            get { return message; }
            set { message = value; }

        }
    }
} 

我在这里打开一个 exe 作为客户端并将数据发送到我的服务器。

using HandyControl.Data;
using System;
using System.Diagnostics;
using System.Net.Sockets;
using System.Net;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using Script_Launcher.Validation;
using System.Threading.Tasks;

namespace Script_Launcher.Views
{
    public partial class MainWindow
    {
        public MainWindow()
        {
            InitializeComponent();
        }


        TcpListener server;
        TcpClient clientconnection;

        private void ListBoxItem_Selected_1(object sender, RoutedEventArgs e)
        {
            

            foreach (var process in Process.GetProcessesByName("OSP_Analysis"))
            {
                process.Kill();
            }

            Process.Start(@"C:\Users\path\OSP_Analysis");

            Task.Run(() =>
            {
                //Vars
                //TcpListener server;
                //TcpClient clientconnection;

                server = new TcpListener(IPAddress.Parse("127.0.0.1"), 8088); //Opens Server on said port
                server.Start(); //Starts listener
                Trace.WriteLine("Server started...");
                clientconnection = server.AcceptTcpClient(); //Accepts Request

                NetworkStream DataStream = clientconnection.GetStream(); //Gets data stream
                byte[] buffer = new byte[clientconnection.ReceiveBufferSize];
                int Data = DataStream.Read(buffer, 0, clientconnection.ReceiveBufferSize); //Recieves data (encoded)
                Message.Messager = Encoding.ASCII.GetString(buffer, 0, Data); //Decodes data (python .encode() function uses the ASCII code)

                clientconnection.Close();
                server.Server.Close();
            });

        }
    }
}

尝试使用比较来更新文本块

using System.Net.Sockets;
using System.Net;
using System.Text;
using System;
using System.Windows.Controls;
using System.Diagnostics;
using System.Threading;
using System.Drawing.Text;
using System.Threading.Tasks;
using System.IO;
using System.Windows;
using static Script_Launcher.Views.OilPerformance;
using System.Runtime.Remoting.Messaging;
using System.Windows.Media;
using Script_Launcher.Validation;

namespace Script_Launcher.Views
{
    /// <summary>
    /// Interaction logic for OilPerformance
    /// </summary>
    public partial class OilPerformance : UserControl
    {
        public OilPerformance()
        {
            InitializeComponent();

            string message = Message.Messager;
            Trace.WriteLine(message);

            if (message == "1500")
            {
                PASSFAIL.Text = "PASS!";
                PASSFAIL.Foreground = new SolidColorBrush(Colors.Green);
            }
            else if (message == "1501")
            {
                PASSFAIL.Text = "FAIL!";
                PASSFAIL.Foreground = new SolidColorBrush(Colors.Red);
            }
            else
            {
                PASSFAIL.Text = "WAITING...";
                PASSFAIL.Foreground = new SolidColorBrush(Colors.Orange);
            }
        }
    }

}

最后是 XAML

<UserControl x:Class="Script_Launcher.Views.OilPerformance"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:prism="http://prismlibrary.com/" 
             xmlns:hc="https://handyorg.github.io/handycontrol"
             prism:ViewModelLocator.AutoWireViewModel="True">
    <Grid>
        <Grid Margin="20" Background="{DynamicResource RegionBrush}">
        </Grid>

        <Grid Margin="40" VerticalAlignment="Center" HorizontalAlignment="Center">
            <StackPanel Margin="32,64,32,32" VerticalAlignment="Center">
            <TextBlock x:Name="PASSFAIL" Margin="0,15,0,-15" FontSize="72"></TextBlock>
            </StackPanel>
        </Grid>
    </Grid>
</UserControl>
