Array类属于System命名空间,在下文中一共展示了Array类的2个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于系统推荐出更棒的C#代码示例。

示例1: Main

//引入命名空间
using System;
public class SamplesArray
{

    public static void Main()
    {

        // Creates and initializes a new integer array and a new Object array.
        int[] myIntArray = new int[5] { 1, 2, 3, 4, 5 };
        Object[] myObjArray = new Object[5] { 26, 27, 28, 29, 30 };

        // Prints the initial values of both arrays.
        Console.WriteLine("Initially,");
        Console.Write("integer array:");
        PrintValues(myIntArray);
        Console.Write("Object array: ");
        PrintValues(myObjArray);

        // Copies the first two elements from the integer array to the Object array.
        System.Array.Copy(myIntArray, myObjArray, 2);

        // Prints the values of the modified arrays.
        Console.WriteLine("\nAfter copying the first two elements of the integer array to the Object array,");
        Console.Write("integer array:");
        PrintValues(myIntArray);
        Console.Write("Object array: ");
        PrintValues(myObjArray);

        // Copies the last two elements from the Object array to the integer array.
        System.Array.Copy(myObjArray, myObjArray.GetUpperBound(0) - 1, myIntArray, myIntArray.GetUpperBound(0) - 1, 2);

        // Prints the values of the modified arrays.
        Console.WriteLine("\nAfter copying the last two elements of the Object array to the integer array,");
        Console.Write("integer array:");
        PrintValues(myIntArray);
        Console.Write("Object array: ");
        PrintValues(myObjArray);
    }

    public static void PrintValues(Object[] myArr)
    {
        foreach (Object i in myArr)
        {
            Console.Write("\t{0}", i);
        }
        Console.WriteLine();
    }

    public static void PrintValues(int[] myArr)
    {
        foreach (int i in myArr)
        {
            Console.Write("\t{0}", i);
        }
        Console.WriteLine();
    }
}

输出:

Initially,
integer array:  1       2       3       4       5
Object array:   26      27      28      29      30

After copying the first two elements of the integer array to the Object array,
integer array:  1       2       3       4       5
Object array:   1       2       28      29      30

After copying the last two elements of the Object array to the integer array,
integer array:  1       2       3       29      30
Object array:   1       2       28      29      30

示例2: for

// Creates and initializes a new three-dimensional Array of type Int32.
Array myArr = Array.CreateInstance(typeof(Int32), 2, 3, 4);
for (int i = myArr.GetLowerBound(0); i <= myArr.GetUpperBound(0); i++)
{
    for (int j = myArr.GetLowerBound(1); j <= myArr.GetUpperBound(1); j++)
    {
        for (int k = myArr.GetLowerBound(2); k <= myArr.GetUpperBound(2); k++)
        {
            myArr.SetValue((i * 100) + (j * 10) + k, i, j, k);
        }
    }
}

// Displays the properties of the Array.
Console.WriteLine("The Array has {0} dimension(s) and a total of {1} elements.", myArr.Rank, myArr.Length);
Console.WriteLine("\tLength\tLower\tUpper");
for (int i = 0; i < myArr.Rank; i++)
{
    Console.Write("{0}:\t{1}", i, myArr.GetLength(i));
    Console.WriteLine("\t{0}\t{1}", myArr.GetLowerBound(i), myArr.GetUpperBound(i));
}

// Displays the contents of the Array.
Console.WriteLine("The Array contains the following values:");
PrintValues(myArr);

void PrintValues(Array myArray)
{
    System.Collections.IEnumerator myEnumerator = myArray.GetEnumerator();
    int i = 0;
    int cols = myArray.GetLength(myArray.Rank - 1);
    while (myEnumerator.MoveNext())
    {
        if (i < cols)
        {
            i++;
        }

        {
            Console.WriteLine();
            i = 1;
