C＃中的布爾幫助-如何格式化random1是否匹配num1

Question

我被指示這樣做：“在布爾值中跟蹤每個數字的匹配狀態，檢查所有三個布爾值匹配變量，如果它們都為真，則我們與獲勝數字匹配，退出while循環”

我90％完成了這項作業，但不確定我是否正確使用bool。

我假設他要我檢查randomNum1是否匹配userEnteredNum1。

但我正在努力格式化。

我首先這樣做：

     bool doTheyMatch1 = true

但是我不知道從那里去哪里。 所以我去了一個比較熟悉的“如果”陳述

    if (random1 = userEntered1stDigit)

並收到“無法將類型int隱式轉換為bool”錯誤。 任何建議或有用的鏈接都是最歡迎的！

為了更有用，這是我的整個代碼：

       public Form1()
    {
        InitializeComponent();
    }

    //DECLARE CLASS LEVEL FIELD VARIABLES
    int CONST_cashPayoutPick3 = 500;
    int CONST_cashPayoutPick4 = 5000;
    int CONST_cashPayoutPick5 = 50000;

    private void myBtnGenRandomNumbers_Click(object sender, EventArgs e)
    {
        //DECLARE LOCAL VARIABLES
        int userEntered1stDigit = 0;
        int userEntered2ndDigit = 0;
        int userEntered3rdDigit = 0;


        //INPUT-VALIDATION
        //winning number: validate the 1st digit to be numeric, if not display error message and return
        if (int.TryParse(myTxtBox1stDigit.Text, out userEntered1stDigit))
        {
            //ok
        }
        else
        {
            MessageBox.Show("Please enter a number in the first box");
            return;
        }
        //winning number: validate the 2nd digit to be numeric, if not display error message and return
        if (int.TryParse(myTxtBox2ndDigit.Text, out userEntered2ndDigit))
        {
            //ok
        }
        else
        {
            MessageBox.Show("Please enter a number in the second box");
            return;
        }
        //winning number: validate the 3rd digit to be numeric, if not display error message and return
        if (int.TryParse(myTxtBox3rdDigit.Text, out userEntered3rdDigit))
        {
            //ok
        }
        else
        {
            MessageBox.Show("Please enter a number in the third box");
            return;
        }


        //INITIALIZE ANY VARIABLES
        userEntered1stDigit = int.Parse(myTxtBox1stDigit.Text);
        userEntered2ndDigit = int.Parse(myTxtBox2ndDigit.Text);
        userEntered3rdDigit = int.Parse(myTxtBox3rdDigit.Text);

        //GOOD SO FAR

        //PROCESSING
        //setup your own Random number generator object
        int random1 = 0;
        int random2 = 0;
        int random3 = 0;

        Random myRandomNumberObject = new Random();
        int matchNum1;
        int matchNum2;
        int matchNum3;

        //clear the list box
        myListBoxResults.Items.Clear();

        //set number of attempts = 0
        int myAttemptsInt;
        myAttemptsInt = 0;


        //LOOP THROUGH AND CREATE SETS OF 3 RANDOM DIGITS EACH TIME THROUGH LOOP UNTIL A MATCH IS FOUND OR TRY 1,000 TIMES
        while (myAttemptsInt <= 1000) 
        {

            if (myAttemptsInt <= 999)
            {
                //ok
            }
            else
            {
                break;
            }

            //get next random digit generated from 0 to 9, for your generated digit position 1
            random1 = myRandomNumberObject.Next(10);
            //get next random digit generated from 0 to 9, for your generated digit position 2
            random2 = myRandomNumberObject.Next(10);
            //get next random digit generated from 0 to 9, for your generated digit position 3
            random3 = myRandomNumberObject.Next(10);


            //display the number of match attempts so far

            //attempt # originally went here
            myAttemptsInt = myAttemptsInt + 1;

            int index = myListBoxResults.Items.Add("Attempt # " + myAttemptsInt);

            //display the generated digit 1,2,3 in the labels on the Form

            matchNum2 = random2;
            myLabelGenerated2ndDigit.Text = matchNum2.ToString();
            matchNum3 = random3;

            //for any generated digit that matches the winning digit,

輕松，用==更改=

在任何C風格中， =分配並返回分配的值， ==進行布爾運算並返回true或false

另外，您可以避免

bool theyMatch = (numberOne == numberTwo) && (numberThree == numberFour) && (numberFive == numberSix);

另外，在測試bool ，無需與true進行比較，因為它已經是bool

if(theyMatch == true)
{
   //your code
}

//Behaves the same as 

if(theyMatch)
{

   //Your code

}
