C# 单击1次后禁用按钮

我正在尝试为游戏制作简单的网格。我对c#和编程非常熟悉。有人能帮我限制按钮的点击吗。我只想在我的网格中创建一个玩家，所以在单击一次后，我想限制用户创建更多玩家。我需要你的专家帮助

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);

    }  

protectedvoid SetClicks（）
{
foreach（此面板1.控件中的控件c）
{
如果（c是按钮）
{
按钮who=c作为按钮；
who.Click+=新事件处理程序（WhoClicked）；
}
}
}
受保护的void MakeButtons（）
{
rowNum=UpDownRow.Text；
intnr=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）；
对于（int行=0；行

我想你会想要：

假设

按钮2

以启用状态启动

private void button2_Click(object sender, EventArgs e)
{

    picSymbol = Properties.Resources.Player;


    //Will only run if button is disabled, which is after the first player creation.

        button2.Enabled = false;
        btn.Text = "Game Disabled";


} 

正如在评论中提到的，可能您的网格有许多按钮，并且都与同一事件挂钩

在本例中，您将使用

发送方

，这是触发事件的按钮

private void button2_Click(object sender, EventArgs e)
{

    picSymbol = Properties.Resources.Player;
    Button btn = sender as Button;

    //Will only run if button is disabled, which is after the first player creation.
    if (!btn.Enabled){
        MessageBox.Show("Too Many Player", "Player number exceed",
        MessageBoxButtons.OK, MessageBoxIcon.Error);

        //or

        btn.Text = "Game Disabled";
    }
    else
    {
        btn.Enabled = false;
    }

}

当用户第二次单击“已启用”按钮时，必须在禁用按钮或显示消息框之间进行选择。禁用的按钮不响应用户活动，因此您无法响应第二次单击

大多数WinForms用户非常习惯于禁用控件-您可以禁用按钮，并将其

文本更改为“游戏完整”，以便用户了解禁用的原因。

如果表单上只有按钮在网格中，您可以这样做

private void button2_Click(object sender, EventArgs e)
{

    picSymbol = Properties.Resources.Player;

    foreach (var control in this.Controls)
    {
        if (control is Button)
        {
            control.Enabled = false;
        }
    }
} 

它还没有经过测试，但应该可以

根据您更新的问题，我在创建按钮时添加了事件绑定，并定义了事件处理程序

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.Image = Properties.Resources.backg;

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

            // hook this button to a click event
            btnNew.Click += new EventHandler(WhoClicked);

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

        }
