c# - 单击 1 次后禁用按钮

Question

我正在尝试为游戏制作简单的网格。我是 c# 和编程的新手。有人可以帮助我如何限制按钮的点击。我只想在我的网格中创建一个玩家，所以在单击 1 次后我想限制用户创建更多玩家。我需要您的专家帮助。

protected void SetClicks()
    {
        foreach ( Control c in this.panel1.Controls)
        {
            if ( c is Button )
            {
                Button who = c as Button;
                who.Click += new EventHandler(WhoClicked);
            }
        }
    }

    protected void MakeButtons()
    {
        rowNum = UpDownRow.Text;
        int nr = Int16.Parse(rowNum);    
        colNum = UpDownColumn.Text;
        int nc = Int16.Parse(colNum);
        int btnHeight = panel1.Height / Int16.Parse(rowNum);
        int btnWidth = panel1.Width / Int16.Parse(colNum);
        for (int row = 0; row < nr; row++)
        {
            for (int column = 0; column < nc; column++)
            {
                Button btnNew = new Button();
                btnNew.Name = "btn_" + column + "_" + row;
                btnNew.Height = btnHeight-5;
                btnNew.Width = btnWidth-5;
                btnNew.Font = new Font("Arial", 20);
               // btnNew.Text = theSymbol;
                btnNew.Image = Properties.Resources.backg;

                btnNew.Visible = true;
               // int CenterPoint = panel1.Width / 3;
                btnNew.Location = new Point(10 + (column* btnNew.Width), 10 + (row* btnNew.Height));

                //Controls.Add(btnNew);
                panel1.Controls.Add(btnNew);

            }
        }
    }



private void button2_Click(object sender, EventArgs e)
    {

            picSymbol = Properties.Resources.Player;

            button2.Enabled = false;
           // want some help here

            MessageBox.Show("Too Many Player", "Player number exceed",
            MessageBoxButtons.OK, MessageBoxIcon.Error);

    }

当用户第二次单击启用的按钮时，您必须选择是禁用按钮还是显示消息框。禁用的按钮不响应用户事件，因此您无法响应第二次点击。

大多数 WinForms 用户都非常习惯于禁用控件 - 您可以做的是禁用按钮并将其 Text 更改为“Game full”，以便用户理解原因被禁用。
