c# - 创建两个不同的随机变量

Question

我正在制作一种扑克游戏，你和一个 ai 对战，你们都会得到一组随机数。在为它创建方法时，我注意到程序总是为两者创建相同的数组。

public short[] GenerateNumbers(short[] playerNumbers)  //The generate numbers method creates an array of random numbers
        {
            Random randNumb = new Random();  //Creation of a random type object called randNumb. This object is the one that creates the random numbers in the array

            playerNumbers = new short[5];  //Stating the length of the player's array

            for (int i = 0; i < playerNumbers.Length; i++)  //This loop creates random numbers for every position in the array
            {
                playerNumbers[i] = (short)randNumb.Next(1, 9);
            }

            playerOneHand = playerNumbers;

            return playerOneHand;
        }

        public short[] GenerateAINumbers(short[] aiNumbers)  //The generate numbers method creates an array of random numbers
        {
            Random randAINumb = new Random();  //Creation of a random type object called randNumb. This object is the one that creates the random numbers in the array

            aiNumbers = new short[5];  //Stating the length of the player's array

            for (int j = 0; j < aiNumbers.Length; j++)  //This loop creates random numbers for every position in the array
            {
                aiNumbers[j] = (short)randAINumb.Next(1, 9);
            }

            aiHand = aiNumbers;

            return aiHand;
        }

您可以创建实例级 Random 对象：

private Random rnd = new Random();

public short[] GenerateNumbers(short[] playerNumbers) {...}

public short[] GenerateAINumbers(short[] aiNumbers) {...}

你可以在你的方法中使用这个 rnd 对象，而不是总是创建一个新对象。
