在方法中顯示二維數組

Question

我正在學習如何編程，在主要用於web之前我已經使用了其他語言，但c＃至少對我來說有點難以理解，而msdn站點太複雜或者我不知道不知道如何正確使用它。努力構建解決數獨謎題程序，我遇到問題時，我嘗試的方法來顯示二維數組，獲得2個錯誤：

using System; 
using System.Collections.Generic; 
using System.Linq; 

class Program 
{ 
    static void Main() 
    { 
     int[,] board = new int[9, 9] {{7, 2, 5, 8, 0, 4, 9, 1, 3}, 
             {0, 0, 0, 0, 3, 0, 0, 0, 4}, 
             {0, 0, 0, 0, 0, 1, 8, 2, 6}, 
             {0, 0, 9, 0, 0, 0, 0, 0, 7}, 
             {0, 1, 0, 6, 2, 8, 0, 4, 0}, 
             {2, 0, 0, 0, 0, 0, 5, 0, 0}, 
             {3, 6, 8, 4, 0, 0, 0, 0, 0}, 
             {0, 0, 0, 0, 7, 0, 0, 0, 8}, 
             {0, 0, 0, 0, 0, 2, 6, 9, 5}}; 

     DisplayBoard(board); 

     List<int> missing = new List<int>(); 
     List<int> present = new List<int>(); 
     int temp = 0; 

     for (int i = 0; i < 1; i++) 
     { 
      for (int j = 0; j < 9; j++) 
      { 
       //Console.Write(board[i, j]); 
       if (board[i, j] == 0) 
       { 
        missing.Add(j); 
       } 
       else 
       { 
        present.Add(board[i, j]); 
       } 

       if (present.Count == 8) 
       { 
        for (int x = 0; x < present.Count; x++) 
        { 
         if (!present.Contains(x)) 
         { 
          temp = x; 
         } 
        } 

        board[i, missing[0]] = temp; 
       } 
      } 
      //missing.ForEach(Console.WriteLine); 
     } 
     DisplayBoard(board); 
    } 




    static void DisplayBoard(int[,]) 
    { 
     for (int i = 0; i < 1; i++) 
     { 
      for (int j = 0; j < 9; j++) 
      { 
       Console.Write(board[i, j]); 
      } 
     } 
    } 
}

你沒到DisplayBoard方法的參數給名

static void DisplayBoard(int[,] board) 
{ 
    for (int i = 0; i < 1; i++) 
    { 
     for (int j = 0; j < 9; j++) 
     { 
      Console.Write(board[i, j]); 
     } 
    } 
}
