请求数组到另一个类

我想从类中请求数组并在程序中使用它。 :base无效

这是我的RandomArray班级

<!-- language: lang-js -->
public class RandomArray

{

    /// <summary>
    /// create a single random number generator
    /// </summary>
    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 -->

我想对这个数组进行排序,所以我创建了另一个类:BubbleSort。

<!-- language: c#-->
class BubbleSort : RandomArray // inherit from RandomArray Class
    {

        public void Bubble() 
        {
            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;
                    }

                }

            }
        }
    }
}
<!-- language: none -->

最后一件事是按钮:

<!-- language: c#-->

private void button2_Click(object sender, EventArgs e)

        {

            BubbleSort p = new BubbleSort();
            p.Bubble();
        }
<!-- language: none -->

如何在同一个阵列上操作(排序)?现在我有错误:'MyProgram' does not contain a constructor that takies 0 arguments. 请帮忙,问候:)

3 个答案:

答案 0 :(得分:1)

正如错误消息告诉您的那样,您的RandomArray类只有一个构造函数,它接受两个参数RandomArray(int min, int max)。这意味着派生类的构造函数必须将这些参数传递给基类的构造函数。

class BubbleSort : RandomArray 
{
     public BubbleSort(int min, int max)
         : base(min, max)
     { }
}

您还可以使用不同的构造函数重载来传递默认参数:

class BubbleSort : RandomArray 
{
     public BubbleSort(int min, int max)
         : base(min, max)
     { }

     public BubbleSort()
         : this(1, 10) 
     { }
}

然而,更重要的是,继承是错误的方法:“冒泡排序”是数组。 “冒泡排序”是一种“排序算法”。

换句话说,如果有的话,你可以这样写:

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

然后将BubbleSort定义为:

class BubbleSort : ISortAlgorithm<int>
{
     public void Sort(int[] array) 
     { 
         ...
     }
}

答案 1 :(得分:0)

选项1:

问题是随机函数缺少构造函数,零参数

public class RandomArray
{
   public RandomArray()
   {}
}

我认为你忘了调用函数,你可以像这样出错

 public void Bubble() :base()
 {

选项2:

或避免现有代码出错

 public void Bubble() :base(1,10)
 {

选项3:

或者您可以像这样修改子类构造函数

 public void Bubble(int i) :base(i)
 {

答案 2 :(得分:0)

如果您已经创建了一个sort类方法,我会将它包含在您的数组类中:

public void Bubble() 
{
    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;
            }

        }

    }
}

然后你就可以使用它:

RandomArray myArray = new RandomArray(0,5);
myArray.Bubble();
