Question

我想在单击按钮后在textBox中显示我的排序数组。我有两个类和一个接口。 First Class生成随机数并在textbox1中显示，第二类生成冒泡排序，我无法在texbox上显示排序数组。

头等舱：

public class RandomArray     
{
    static readonly Random generator = new Random();
    /// <summary>
    /// here are the random numbers stored
    /// </summary>
    int[] array;
    /// <summary>
    /// store the min, max used to generate the data
    /// </summary>
    readonly int min, max;
    /// <summary>
    /// Constructor only needs how the value limits
    /// </summary>
    /// <param name="min">The minimum value (typical 0)</param>
    /// <param name="max">The maximum value (example 100)</param>
    public RandomArray(int min, int max)
    {
        this.min=min;
        this.max=max;
        this.array=new int[0];
    }
    /// <summary>
    /// Fills the array with random numbers
    /// </summary>
    /// <param name="count">The number of data to generate</param>
    public void Fill(int count)
    {
        this.array=new int[count];
        // fill array with random integers
        for (int i=0; i<array.Length; i++)
        {
            array[i]=generator.Next(min, max);
        }
    }        
    /// <summary>
    /// Copy constructor if needed (optional)
    /// </summary>
    /// <param name="other">A RandomArray to copy the data from</param> 
    public RandomArray(RandomArray other)
    {
        this.min=other.min;
        this.max=other.max;
        this.array=(int[])other.array.Clone();
    }
    /// <summary>
    /// Provide the data
    /// </summary>

    public int[] Array { get { return array; } }
    /// <summary>
    /// Provide the limits used
    /// </summary>

    public int Min { get { return min; } }
    public int Max { get { return max; } }
    /// <summary>
    /// Creates a comma separated list of numbers like <c>[45,32,64,..]</c>
    /// </summary>
    public string ToStringList()
    {
        string[] parts=new string[array.Length];
        for (int i=0; i<parts.Length; i++)
        {
            parts[i]=array[i].ToString();
        }
        return "["+string.Join(",", parts)+"]";
    }
    /// <summary>
    /// Shows only the limits used
    /// </summary>
    public override string ToString()
    {
        return string.Format("RandomArray({0},{1})", min, max);
    }
<!-- language: none-->

这是泡泡排序

class BubbleSort :  ISortAlgorithm<int>
{
   public void Sort (int[] array)     
    {
        int temp;
        for (int j = 1; j <= array.Length - 2; j++)
        {
            for (int i = 0; i <= array.Length - 2; i++)
            {
                if (array[i] > array[i + 1])
                {
                    temp = array[i + 1];
                    array[i + 1] = array[i];
                    array[i] = temp;
                }
            }
        }
    }

ISortAlgorithm：

interface ISortAlgorithm<T>
{
    void Sort(T[] array);
}

最后一件事是对文本框的请求：

private void button2_Click(object sender, EventArgs e)
{            
    BubbleSort p = new BubbleSort();
    textBox1.Text = p.ToString();
}

如果我点击按钮程序会显示MyProgram.BubbleSort

我是否会覆盖bubblesort方法？或者是什么？我几乎尝试了一切。 Thanskd和问候。

Answer 1

我觉得你有点困惑。当然，您希望在对数组进行排序后创建RandomArray对象并调用其ToString()方法。

RandomArray r = new RandomArray(1, 100);
r.Fill(50);
BubbleSort b = new BubbleSort();
b.Sort(r.Array);
textBox1.Text = r.ToStringList(); //depending on the requirements

Answer 2

您需要覆盖ToString类

的BubbleSort方法

还有一些事情，

1）您需要将数组保留在BubbleSort类中，以便按照您的方式使用

class BubbleSort :  ISortAlgorithm<int>
{
   private int[] myArray;
   public void Sort (int[] array)     
    {
        myArray = array;
        int temp;
        for (int j = 1; j <= array.Length - 2; j++)
        {
            for (int i = 0; i <= array.Length - 2; i++)
            {
                if (array[i] > array[i + 1])
                {
                    temp = array[i + 1];
                    array[i + 1] = array[i];
                    array[i] = temp;
                }
            }

        }

    }

    public override string ToString()
    {
        StringBuilder sb = new StringBuilder();
        foreach(int i in myArray)
        {
            sb.Append(Convert.ToString(i));
        }
        return sb.ToString();
    }
