Question

我正在尝试生成随机int数字，一旦我生成它们，我想将它们存储在listBox中，然后将它们排在第二个listBox中。我的代码：

        int Min = 0;
        int Max = 6;

        // this declares an integer array with 5 elements
        // and initializes all of them to their default value
        // which is zero
        int[] test2 = new int[6];

        Random randNum = new Random();
        for (int i = 1; i < test2.Length; i++)
        {
            test2[i] = randNum.Next(Min, Max);    
        }
        arrayListbox.ItemsSource = test2;
        Array.Sort(test2);
        foreach (int value in test2)
        {
            arrayListboxOrder.ItemsSource = test2;
        }

Answer 1

ItemsSource需要是一个不同的数组 - 否则它们基本上都有相同的数据。排序一，排序＆＃34;两者＆＃34;。

尝试：

arrayListbox.ItemsSource = test2;
int[] sorted = (int[])test2.Clone();
Array.Sort(sorted);
arrayListboxOrder.ItemsSource = sorted;

Answer 2

        int Min = 0;
        int Max = 6;
        // this declares an integer array with 5 elements
        // and initializes all of them to their default value
        // which is zero
        //int[] test2 = new int[6];

        arrayListboxOrder.ItemsSource = Enumerable.Range(Min, Max).OrderBy(x => Guid.NewGuid()).Take(5).OrderBy(n=>n).ToArray();

创建随机数，将它们存储在数组中并在两个列表框中对它们进行排序c＃
