示例1: Main
//引入命名空间
using System;
public class SamplesArray
{
public static void Main() {
// Create and initialize a new string array.
String[] myArr = {"The", "quick", "brown", "fox", "jumps",
"over", "the", "lazy", "dog"};
// Display the values of the array.
Console.WriteLine(
"The string array initially contains the following values:");
PrintIndexAndValues(myArr);
// Resize the array to a bigger size (five elements larger).
Array.Resize(ref myArr, myArr.Length + 5);
// Display the values of the array.
Console.WriteLine("After resizing to a larger size, ");
Console.WriteLine("the string array contains the following values:");
PrintIndexAndValues(myArr);
// Resize the array to a smaller size (four elements).
Array.Resize(ref myArr, 4);
// Display the values of the array.
Console.WriteLine("After resizing to a smaller size, ");
Console.WriteLine("the string array contains the following values:");
PrintIndexAndValues(myArr);
}
public static void PrintIndexAndValues(String[] myArr) {
for(int i = 0; i < myArr.Length; i++)
{
Console.WriteLine(" [{0}] : {1}", i, myArr[i]);
}
Console.WriteLine();
}
}输出：
The string array initially contains the following values: [0] : The [1] : quick [2] : brown [3] : fox [4] : jumps [5] : over [6] : the [7] : lazy [8] : dog After resizing to a larger size, the string array contains the following values: [0] : The [1] : quick [2] : brown [3] : fox [4] : jumps [5] : over [6] : the [7] : lazy [8] : dog [9] : [10] : [11] : [12] : [13] : After resizing to a smaller size, the string array contains the following values: [0] : The [1] : quick [2] : brown [3] : fox
