如果只匹配一个数字，如何使一个标签变为绿色

Question

我是在右边，只有当我有3个匹配时才会做任何颜色

while (AttemptNumber <= 999)
{
    AttemptNumber = AttemptNumber + 1;   //ALT that i m not going to use : AttemptNumber++

    myString = "Attempt #" + AttemptNumber.ToString();

    myRandom1 = myRandomObj.Next(0, 9);
    myRandom2 = myRandomObj.Next(0, 9);
    myRandom3 = myRandomObj.Next(0, 9);

    random1Label.Text = myRandom1.ToString();
    random2Label.Text = myRandom2.ToString();
    random3Label. Text = myRandom3.ToString();

    AttemptsLbl.Text = AttemptNumber.ToString("#,##0");

    if (myRandom1 == myNum1 && myRandom2 == myNum2 && myRandom3 == myNum3)
    {
        // random label color changing for the label to green if matched
        random1Label.BackColor = Color.LightGreen;
        random2Label.BackColor = Color.LightGreen;
        random3Label.BackColor = Color.LightGreen;

        //we have match for all 3 digits = winner!
        myString = myString + " SUCCESS: " + myNum1 + myNum2 + myNum3 + " vs " + myRandom1 + myRandom2 + myRandom3;

        MessageBox.Show(" Match Found for All 3 Digits - it took " + AttemptNumber + " tries! ");

        Listbox.Items.Add(myString);

        matchFound = true;
        break;
    }
    else
    {
        //we dont have a match

        myString = myString + " Failed: " + myNum1 + myNum2 + myNum3 + " vs " + myRandom1 + myRandom2 + myRandom3;

        random1Label.BackColor = Color.LightGreen;
        random2Label.BackColor = Color.LightGreen;
        random3Label.BackColor = Color.LightGreen;

        Listbox.Items.Add(myString);      
    }

与pic显示器一样，​​我只希望匹配一种颜色的绿色，或者如果匹配两个数字则需要两种颜色。如果只匹配一个数字，如何使一个标签变为绿色？ 如果只有一个标签与一个标签不匹配，如何使标签变为绿色？

我不确定我是否正确理解了你的问题。我想这就是你要找的东西。

1. 每次迭代时将所有标签背景颜色重置为灰色

2. 只有当该特定数字匹配时，才有条件地显示每个标签的背景。

    while (AttemptNumber <= 999)
   {
      //Reset the Background Color for every Iteration
     random1Label.BackColor = Color.Grey;//Initial Background color
      random2Label.BackColor = Color.Grey;//Initial Background color
      random3Label.BackColor = Color.Grey;//Initial Background color  
   
   
   
     AttemptNumber = AttemptNumber + 1;   //ALT that i m not going to use : AttemptNumber++
   
   myString = "Attempt #" + AttemptNumber.ToString();
   
       myRandom1 = myRandomObj.Next(0, 9);
       myRandom2 = myRandomObj.Next(0, 9);
       myRandom3 = myRandomObj.Next(0, 9);
   
       random1Label.Text = myRandom1.ToString();
       random2Label.Text = myRandom2.ToString();
       random3Label. Text = myRandom3.ToString();
   
       AttemptsLbl.Text = AttemptNumber.ToString("#,##0");
   
       if (myRandom1 == myNum1 && myRandom2 == myNum2 && myRandom3 == myNum3)
       {
   
           // random label color changing for the label to green if matched
   
          random1Label.BackColor = Color.LightGreen;
          random2Label.BackColor = Color.LightGreen;
          random3Label.BackColor = Color.LightGreen;
   
           //we have match for all 3 digits = winner!
   
           myString = myString + " SUCCESS: " + myNum1 + myNum2 + myNum3 + " vs " + myRandom1 + myRandom2 + myRandom3;
   
   
   
   
   
           MessageBox.Show(" Match Found for All 3 Digits - it took " + AttemptNumber + " tries! ");
   
   
           Listbox.Items.Add(myString);
   
           matchFound = true;
           break;
   
   
        }
            else
        {
   
           //we dont have a match
   
           myString = myString + " Failed: " + myNum1 + myNum2 + myNum3 + " vs " + myRandom1 + myRandom2 + myRandom3;
        if (myRandom1 == myNum1)
           random1Label.BackColor = Color.LightGreen;
        if (myRandom2 == myNum2)
            random2Label.BackColor = Color.LightGreen;
        if (myRandom3 == myNum3)
           random3Label.BackColor = Color.LightGreen;
   
          Listbox.Items.Add(myString);      
   
   
    }
