一、一維數組的創建與遍歷
方法一：
類型[ ]變量=new 類型[ ];l例如：string a=new string[ var int]
若使用new關鍵字，則方括號內必須聲明一個int類型的值來表示長度
也可以：string[ ] a=new string[ ]{ }
方法二：
string[ ] a={"a","b","c","d"};
一維數組的遍歷：for和foreach
using System;
namespace practice3
{
class MainClass
{
public static void Main(string[] args)
{
string[] a = new string[]{ "huang", "jun", "kai", "h", "j", "k" };
for (int i = 0; i < a.Length; i++)
{
Console.WriteLine (a[i]);
}
foreach (string item in a)
{
Console.WriteLine (item);
}
}
}
}
二、二維數組的創建與遍歷
方法一：
string[,] a=new string[5,3]
string[,] a=new string[5,3]{ {"a","b","c"},{"d","e","f"},{"g","h","i"},{"j","k","i"},{"l","m","n"}};
方法二：
string[, ] a={ {"a","b","c"},{"d","e","f"},{"g","h","i"},{"j","k","i"},{"l","m","n"}};
二維數組的遍歷：for和foreach
知識點：GetUpperBound（int variable>維度數字<）；獲取指定維度的上限
GetLowerBound(int variable>維度數字<);獲取指定維度的下限
using System;
namespace practice3
{
class MainClass
{
public static void Main(string[] args)
{
string[,] a = new string[,]
{ { "張三", "男", "18" }, { "李四", "女", "19" }, { "王五", "男", "18" } };
for (int i = 0; i < a.GetUpperBound (0)+1; i++)
{
for (int j = 0; j < a.GetUpperBound (1)+1; j++)
{
Console.Write(a[i,j]+"\t");
}
Console.WriteLine ();
}
}
}
}
