C# 程式迴圈遍歷二維陣列


宣告一個二維陣列 −

string[,] array = new string[3, 3];

在陣列中設定元素 −

array[0, 0] = "One";
array[0, 1] = "Two";
array[0, 2] = "Three";
array[1, 0] = "Four";
array[1, 1] = "Five";
array[1, 2] = "Six";
array[2, 0] = "Seven";
array[2, 1] = "Eight";
array[2, 2] = "Nine";

現在,獲取上界以獲取迴圈遍歷陣列的維度 −

int uBound0 = array.GetUpperBound(0);
int uBound1 = array.GetUpperBound(1);

在巢狀迴圈中迭代,直至達到上述兩個值,如下面的程式碼所示 −

示例

 動態演示

using System;
using System.Collections.Generic;
using System.Linq;
public class Demo {
   public static void Main() {
      string[,] array = new string[3, 3];
      array[0, 0] = "One";
      array[0, 1] = "Two";
      array[0, 2] = "Three";
      array[1, 0] = "Four";
      array[1, 1] = "Five";
      array[1, 2] = "Six";
      array[2, 0] = "Seven";
      array[2, 1] = "Eight";
      array[2, 2] = "Nine";
      // getting upper bound
      int uBound0 = array.GetUpperBound(0);
      int uBound1 = array.GetUpperBound(1);
      for (int i = 0; i <= uBound0; i++) {
         for (int j = 0; j <= uBound1; j++) {
            string res = array[i, j];
            Console.WriteLine(res);
         }
      }
      Console.ReadLine();
   }
}
