c#中的布尔帮助--如何格式化random1是否与num1匹配

Question

我被指示这样做：“在布尔检查中跟踪每个数字的匹配状态，检查所有三个布尔匹配变量，如果它们都是真的，那么我们就有一个与获胜数字匹配的，退出while循环”。

我已经完成了90%的任务，但我不知道如何正确地使用bool。

我猜他是想让我看看randomNum1是否和userEnteredNum1匹配。

但我很难把它格式化。

我一开始就是这么做的：

     bool doTheyMatch1 = true

但我不知道从那里往哪里走。所以我去看了一个更熟悉的“如果”声明

    if (random1 = userEntered1stDigit)

并得到“无法隐式将int类型转换为bool”错误。任何建议或有用的链接都是最欢迎的！

更有帮助的是，下面是我的全部代码：

       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

        int random1 = 0;
        int random2 = 0;

        Random myRandomNumberObject = new Random();
        int matchNum1;

        int matchNum3;

        //clear the list box

        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 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

简单，用==更改==

在任何C类型中，=分配并返回赋值，==执行布尔操作并返回true或false

另外，你也可以避免如果做

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

此外，在测试bool时，不需要与true进行比较，因为它已经是一个bool

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

//Behaves the same as 

if(theyMatch)
{

   //Your code

}
