c# 2维数组 取一维
In the below example, we are declaring an integer array (one dimensional) with following styles:
在下面的示例中,我们声明具有以下样式的整数数组(一维) :
1) One dimensional Array declaration with initialization (without array size)
1)具有初始化的一维数组声明(无数组大小)
Example:
例:
int[] arr1 = { 12, 45, 56, 78, 89 };
In this style, arr1 will automatic occupy the size of the array based on given elements.
在这种样式中, arr1将根据给定的元素自动占据数组的大小。
2) Dynamic One dimensional Array declaration with fixed size
2)具有固定大小的动态一维数组声明
Example:
例:
int[] arr2 = new int[5];
In this style, arr2 will occupy the size for 5 integers dynamically.
在这种样式中, arr2将动态占用5个整数的大小。
3) Dynamic One dimensional Array declaration with variable size
3)具有可变大小的动态一维数组声明
Example:
例:
int[] arr3 = new int[size];
In this style, we will read the size of the arr3 first and then declare the array dynamically.
在这种样式中,我们将先读取arr3的大小,然后动态声明数组。
Example: In the below given example – we are using these 3 styles to declare an array.
示例:在下面给出的示例中–我们使用这3种样式声明一个数组。
Program:
程序:
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace Arrays{ class Program { static void Main(string[] args) { //Single Dimension Console.WriteLine("Type 1 : Declaration"); int[] arr1 = { 12, 45, 56, 78, 89 }; foreach(int item in arr1) { Console.Write("{0}\t", item); } Console.WriteLine("\n\nType 2 : Declaration"); int[] arr2 = new int[5]; Console.WriteLine("Enter 5 Values:"); for(int i=0;i
