使用new关键字创建数组的实例-
int [] a = new int[5];
new运算符用于创建对象或实例化对象。在此示例中,使用新的-为类创建对象-
using System; namespace CalculatorApplication { class NumberManipulator { public void swap(int x, int y) { int temp; temp = x; /* save the value of x */ x = y; /* put y into x */ y = temp; /* put temp into y */ } static void Main(string[] args) { NumberManipulator n = new NumberManipulator(); /* local variable definition */ int a = 100; int b = 200; Console.WriteLine("Before swap, value of a : {0}", a); Console.WriteLine("Before swap, value of b : {0}", b); /* calling a function to swap the values */ n.swap(a, b); Console.WriteLine("After swap, value of a : {0}", a); Console.WriteLine("After swap, value of b : {0}", b); Console.ReadLine(); } } }
输出结果
Before swap, value of a : 100 Before swap, value of b : 200 After swap, value of a : 100 After swap, value of b : 200
