C# 如何为网络客户端传输更新

我有一个C#的应用程序，使用表单，每次右键单击表单时都会放置一个标签。此标签可以四处移动、重新调整大小并修改其颜色。 到目前为止还不错，但我想制作一个服务器，它将接收我所做的一切，并将其发送给其他客户机，这样他们就可以看到我所做的一切，而且他们也可以做完全相同的事情。我制作了EventHandler，但我不知道如何通过网络发送信息，也不知道要发送什么信息来更新每个客户端的表单

    internal System.Windows.Forms.ContextMenu mnuForm;
    internal System.Windows.Forms.MenuItem mnuNewSquare;
    internal System.Windows.Forms.ContextMenu mnuLabel;
    internal System.Windows.Forms.MenuItem mnuColorChange;
private void mnuNewSquare_Click(object sender, System.EventArgs e)
    {
        // Create and configure the "square".
        Label newLabel = new Label();
        newLabel.Size = new Size(40, 40);
        newLabel.BorderStyle = BorderStyle.FixedSingle;

        // To determine where to place the label, you need to convert the 
        // current screen-based mouse coordinates into relative form coordinates.
        newLabel.Location = this.PointToClient(Control.MousePosition);

        // Attach a context menu to the label.
        newLabel.ContextMenu = mnuLabel;

        // Connect the label to all its event handlers.
        newLabel.MouseDown += new MouseEventHandler(lbl_MouseDown);
        newLabel.MouseMove += new MouseEventHandler(lbl_MouseMove);
        newLabel.MouseUp += new MouseEventHandler(lbl_MouseUp);

        // Add the label to the form.
        this.Controls.Add(newLabel);

    }
    // Keep track of when fake drag or resize mode is enabled.
    private bool isDragging = false;
    private bool isResizing = false;

    // Store the location where the user clicked on the control.
    private int clickOffsetX, clickOffsetY;

    private void lbl_MouseDown(object sender,
        System.Windows.Forms.MouseEventArgs e)
    {
        // Retrieve a reference to the active label.
        Control currentCtrl;
        currentCtrl = (Control)sender;

        if (e.Button == MouseButtons.Right)
        {
            // Show the context menu.
            currentCtrl.ContextMenu.Show(currentCtrl, new Point(e.X, e.Y));
        }
        else if (e.Button == MouseButtons.Left)
        {
            clickOffsetX = e.X;
            clickOffsetY = e.Y;

            if ((e.X + 5) > currentCtrl.Width && (e.Y + 5) > currentCtrl.Height)
            {
                // The mouse pointer is in the bottom right corner,
                // so resizing mode is appropriate.
                isResizing = true;
            }
            else
            {
                // The mouse is somewhere else, so dragging mode is
                // appropriate.
                isDragging = true;
            }
        }
    }

    private void lbl_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e)
    {
        // Retrieve a reference to the active label.
        Control currentCtrl;
        currentCtrl = (Control)sender;

        if (isDragging)
        {
            // Move the control.
            currentCtrl.Left += e.X - clickOffsetX;
            currentCtrl.Top += e.Y - clickOffsetY;
        }
        else if (isResizing)
        {
            // Resize the control.
            currentCtrl.Width = e.X;
            currentCtrl.Height = e.Y;
        }
        else
        {
            // Change the pointer if the mouse is in the bottom corner.
            if ((e.X + 5) > currentCtrl.Width && (e.Y + 5) > currentCtrl.Height)
            {
                currentCtrl.Cursor = Cursors.SizeNWSE;
            }
            else
            {
                currentCtrl.Cursor = Cursors.Arrow;
            }
        }
    }
    private void lbl_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
    {
        isDragging = false;
        isResizing = false;
    }

    private void mnuColorChange_Click(object sender, System.EventArgs e)
    {
        // Show color dialog.
        ColorDialog dlgColor = new ColorDialog();
        dlgColor.ShowDialog();

        // Change label background.
        mnuLabel.SourceControl.BackColor = dlgColor.Color;

    }

    private void DrawingSquares_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
    {
        if (e.Button == MouseButtons.Right)
        {
            this.ContextMenu.Show(this, new Point(e.X, e.Y));
        }

    }

这是form1.cs的代码，下一个代码是form1.designer.cs的代码

 private void InitializeComponent()
    {
       // this.SuspendLayout();
        // 
        // Form1
        // 
        this.mnuForm = new System.Windows.Forms.ContextMenu();
        this.mnuNewSquare = new System.Windows.Forms.MenuItem();
        this.mnuLabel = new System.Windows.Forms.ContextMenu();
        this.mnuColorChange = new System.Windows.Forms.MenuItem();
        // 
        // mnuForm
        // 
        this.mnuForm.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {
                                                                                this.mnuNewSquare});
        // 
        // mnuNewSquare
        // 
        this.mnuNewSquare.Index = 0;
        this.mnuNewSquare.Text = "Create New Square";
        this.mnuNewSquare.Click += new System.EventHandler(this.mnuNewSquare_Click);
        // 
        // mnuLabel
        // 
        this.mnuLabel.MenuItems.AddRange(new System.Windows.Forms.MenuItem[] {
                                                                                 this.mnuColorChange});
        // 
        // mnuColorChange
        // 
        this.mnuColorChange.Index = 0;
        this.mnuColorChange.Text = "Change Color";
        this.mnuColorChange.Click += new System.EventHandler(this.mnuColorChange_Click);
        // 
        // DrawingSquares
        // 
        this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
        this.ClientSize = new System.Drawing.Size(628, 426);
        this.ContextMenu = this.mnuForm;
        this.Name = "DrawingSquares";
        this.Text = "DrawingSquares";
        this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.DrawingSquares_MouseDown);


    }

这在应用程序的客户端完成，您可以在客户端绘制标签并修改其属性。我需要一些关于如何做服务器端的帮助，非常感谢您的帮助，提前谢谢您。

请不要在标题前加上“c#”之类的前缀。这就是标签的作用。你的代码都与你的问题无关。我添加了此代码，以便你可以看到我是如何将标签添加到表单的，以及我是如何调整标签大小或移动标签的。我不知道通过网络发送什么信息，我的意思是，每次我移动时都有什么需要更新的？
