从另一种形式访问控件值 [英] Accessing a controls value from another form

问题描述

我做了一个简单的井字游戏.我有两种形式，Form1和frmStats.在我的frmStats上，我有一个标签lblDraw. 我想要这样，当玩家平局时，标签将增加1.如何从Form1的代码访问它?

I made a simple tic,tac,toe game. I have two forms, Form1 and frmStats. on my frmStats I have a Label lblDraw. I want it so when the players get in a draw, the label will increment by one. How do I access that from Form1's code?

我的Form1代码:

if (winner != 0)
  this.Text = String.Format("Player {0} Wins!", winner);
else if (winner == 0 && turnCounter == 9)
  this.Text = "Draw!";
 //this is where i want/think the code should be to change the label
else
  ...

推荐答案

首先将标签lblDraw设置为

以frmStats形式

In frmStats form

 public string strNumber
 {
    get
    {
        return lblDraw.Text;
    }
    set
    {
        lblDraw.Text = value;
    }
 }

Form1

    if (winner != 0)
        this.Text = String.Format("Player {0} Wins!", winner);
    else if (winner == 0 && turnCounter == 9)
    {
        this.Text = "Draw!";
        //this is where i want/think the code should be to change the label
        frmStats frm = new frmStats();
        string number = frm.strNumber;
        frm.strNumber = (Convert.ToInt32(number) + 1).ToString(); //incrementing by 1
    }

，否则只需将Label lblDraw修饰符设置为 public ，这是不推荐的.

or else simply set the Label lblDraw modifier as public, which is not recommended.
