如何将值从文本框传递到不同表单上的标签

本文关键字：表单 标签 文本 | 更新日期: 2023-09-27 18:25:38

我接到了一个制作井字游戏（尺寸8*8）的任务，到目前为止，我设法对主游戏进行了编码，但我在将玩家名称的值从新游戏表单传递到主表单时遇到了问题，有人能帮我吗？

主窗体的代码

    public void NameValue1(TextBox NV1)
    {
        lblName1.Text = NV1.Text;
    }
    public void NameValue2(TextBox NV2)
    {
        lblName2.Text = NV2.Text;
    }
private void mnuNewGame_Click(object sender, EventArgs e)
    {            
        iFlag = 1; // This is used to run the paint function on the form
        StartGame();
        for (int i = 0; i < 64; i++)
        {
            this._btn[i].Click += new System.EventHandler(this.ClickControl);
            this._btn[i].MouseMove += new MouseEventHandler(this.MoveControl); // DEBUG // these 2 allow me to check 'does my mouse hover on the right box?'
            this._btn[i].MouseLeave += new System.EventHandler(this.LeaveControl); // DEBUG //
        }
    }
public void StartGame()
    {
        frmNewGame OpenForm = null;
        OpenForm = new frmNewGame();
        OpenForm.ShowDialog();
        //lblName1.Text = "Player 1"; // PLACEHOLDER // these 2 are what I'm trying to replace to accept values from newgameform
        //lblName2.Text = "Player 2"; // PLACEHOLDER //
        lblName1.Visible = true;
        lblName2.Visible = true;
        Random RandomNumber = new Random();
        int Start = RandomNumber.Next(0, 3);
        if (Start == 1)
        {
            PlayerTurn = "Player1";
            lblName1.Font = new Font("Microsoft Sans Serif", 17, FontStyle.Underline | FontStyle.Bold);
            lblName2.Font = new Font("Microsoft Sans Serif", 17, FontStyle.Regular | FontStyle.Bold);
        }
        else if (Start == 2)
        {
            PlayerTurn = "Player2";
            lblName1.Font = new Font("Microsoft Sans Serif", 17, FontStyle.Regular | FontStyle.Bold);
            lblName2.Font = new Font("Microsoft Sans Serif", 17, FontStyle.Underline | FontStyle.Bold);
        }
        NumberTurn = 0;
        for (int i = 0; i < 64; i++)
        {
            _btn[i].Text = "";
            _btn[i].BackColor = Color.Yellow;
            _btn[i].Visible = true;
            _btn[i].Enabled = true;
        }
    }

新游戏形式的代码

public delegate void PassName1(TextBox tbxPlayerName1);
public delegate void PassName2(TextBox tbxPlayerName2);
private void btnOK_Click(object sender, EventArgs e)
    {
        frmConnectFour frmGame = new frmConnectFour();
        PassName1 PN1 = new PassName1(frmGame.NameValue1);
        PassName2 PN2 = new PassName2(frmGame.NameValue2);
        this.DialogResult = DialogResult.OK;
    }

正如你所看到的，我已经准备好了表单之间的连接来读取玩家名称文本框（没有错误），但我在如何将其传递给主表单上的startgame（）函数方面遇到了问题

p.S：如果需要，我可以上传解决方案

如何将值从文本框传递到不同表单上的标签

这个话题已经讨论了数千次，但每次都有点不同
在这种情况下，您可以在newgameform中创建两个公共属性
当用户单击"确定"按钮时，将使用newgameform上的TextBoxes值设置属性
然后很容易从主表单中读取它们

public string Player1 {get; private set;}
public string Player2 {get; private set;}
private void btnOK_Click(object sender, EventArgs e)
{
    this.Player1 = txtBoxForPlayer1.Text;
    this.Player2 = txtBoxForPlayer2.Text;
    this.DialogResult = DialogResult.OK;
}

并且以的主要形式

public void StartGame()
{
    using(frmNewGame OpenForm = new frmNewGame())
    {
        if(DialogResult.OK == OpenForm.ShowDialog())
        {
           lblName1.Text = OpenForm.Player1;
           lblName2.Text = OpenForm.Player2;
           lblName1.Visible = true;
           lblName2.Visible = true;
           .....
        }
    }
}
