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++;
}
else
{
Console.WriteLine();
i = 1;
}
Console.Write("\t{0}", myEnumerator.Current);
}
Console.WriteLine();
}输出：
The Array has 3 dimension(s) and a total of 24 elements. Length Lower Upper 0: 2 0 1 1: 3 0 2 2: 4 0 3 The Array contains the following values: 0 1 2 3 10 11 12 13 20 21 22 23 100 101 102 103 110 111 112 113 120 121 122 123
