缩短长 if 语句 [英] Shorting long if statement

问题描述

我花了几个小时制作井字游戏，主要使用 if else 语句，我只是复制和粘贴了一些代码......

I have spent hours making a tic tac toe game just using mainly if else statements, some of the code I just copy and pasted...

我如何只创建代码的一个实例，然后稍后再引用它?- 当我需要该代码时，而不是每次都复制和粘贴大量代码行.在这段代码中，我得到一个 1 到 10 之间的随机数，这个数字将存储在 RI 中……然后当轮到 Ai 时，计算机将在按钮中随机输入一个 X，然后使用此代码它会检查确定计算机是否获胜.我希望这是有道理的 =)

How would I just create one instance of the code, then refer to it later on? - when I need that code, instead of just copy and pasting massive lines of code each time. In this block of code, I am getting a random number between 1 to 10 this number will be stored in RI... then when it's Ai's turn the computer will randomly input an X in the button, then using this code it will check to determine if the computer has won. I hope that make sense =)

do
{
    storeRI = rc.Next(0, 10); //storing random number into storeRI so it can be used later on in life. 
    if (storeRI == 1 && btn1.Text == "")
    {
        btn1.Text = "X";
        Turn = 1;
        if (btn1.Text == "X" & btn2.Text == "X" & btn3.Text == "X")
        {
            btn1.BackColor = Color.Green;
            btn2.BackColor = Color.Green;
            btn3.BackColor = Color.Green;

            XScore += 1;
            lblPScoreX.Text = XScore.ToString();

            foreach (Button btn in buttonList)
                 btn.Enabled = false;
        }
        else if (btn1.Text == "X" & btn4.Text == "X" & btn7.Text == "X")
        {
             btn1.BackColor = Color.Green;
             btn4.BackColor = Color.Green;
             btn7.BackColor = Color.Green;

             XScore += 1;
             lblPScoreX.Text = XScore.ToString();

             foreach (Button btn in buttonList)
                btn.Enabled = false;
        }
    }
}

例如这段代码，是我至少复制了 10 次的一些代码，它只是让我的代码看起来很丑陋，很难阅读.

for example this code, is some of the code, that I have copied atleast 10 times, and it just makes me code look ugly and really hard to read.

任何时候你复制了代码，你都应该尝试把它移到一个方法中.然后您可以直接调用该方法.在你的例子中，一个方法可以很容易地接受三个按钮来影响，并直接处理它们.

Any time you have copied code, you should try to move it into a method. You can then just call the method directly. In your case, a method could easily accept the three buttons to affect, and work on them directly.
