如何將我的數據表顯示爲矩陣？

我如何得到我的數據表來獲得以下格式：如何將我的數據表顯示爲矩陣？

   England Germany Holland Spain Germany Russia Japan 

England   x 

Germany     x 

Holland        x 

Spain           x 

Germany            x 

Russia               x 

Japan                 x

我先得到一些答案，但那是另一種方式。我真的希望我的數據表可以用於此。如果你可以幫助我瞭解如何在正確的座標上顯示輸入，這將是很好的。

是否需要在一個控制檯應用程序？在Winforms或WPF中這樣做更容易，更清晰。 – RvdK

是的，它必須是 - 我知道它會在WPF中容易得多 - 我只是希望我可以在WPF中完成它 - 但我不被允許。所以我真的需要一些幫助 – deltu

Litarely沒有人知道 - 即使在MSDN上它總是關於Windows窗體。我只是不知道如何完成這個項目=/ – deltu

我有一個項目上點陣打印機打印時，我改變了我的代碼，它可以幫助你顯示創建一個控制檯項目並替換代碼與我的

哇，看起來不錯。但是，我如何閱讀這個輸入？ – deltu

你測試了我的代碼嗎，現在你想從你的表格創建列表，它的簡單想法更多;） – DeveloperX

我也測試過它，但我一直在忙着自己 - 一遍又一遍地用同樣的東西敲擊 - 現在，我得到了一個新的代碼，它有點不知所措了新的變量：P – deltu

好吧我有點遲到我的例子，但我仍然花了一些時間做到這一點，所以我發佈:) 示例代碼打印表並要求輸入列號，行號和值之後再次打印表以顯示結果。請記住它的示例如何打印矩陣並編輯它的值。

class Program 
{ 
    static void Main(string[] args) 
    { 
     DataTable Matrix = new DataTable(); 
     Matrix.TableName = "Matrix"; 
     Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("Name"))); 
     Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("1 England"))); 
     Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("2 Germany"))); 
     Matrix.Columns.Add(new DataColumn(MakeStringBeutiful("3 France "))); 


     Matrix.Rows.Add("1 England", " x ", "   ", "   "); 
     Matrix.Rows.Add("2 Germany", "   ", " x ", "   "); 
     Matrix.Rows.Add("3 France ", "   ", "   ", " x "); 

     PrintMatrix(Matrix); 
     Console.WriteLine("Enter column number:"); 
     string sx = Console.ReadLine(); 
     int x = int.Parse(sx); 
     Console.WriteLine("Enter row number:"); 
     string sy = Console.ReadLine(); 
     int y = int.Parse(sy); 
     Console.WriteLine("Enter value:"); 
     string v = Console.ReadLine(); 

     SetValue(x, y, v, Matrix); 
     PrintMatrix(Matrix); 
     Console.ReadLine(); 
    } 

    private static void SetValue(int x, int y, string value, DataTable table) 
    { 
     table.Rows[y - 1][x]=MakeStringBeutiful(value); 
    } 

    private static void PrintMatrix(DataTable m) 
    { 
     string s = "|"; 
     foreach (DataColumn item in m.Columns) 
     { 
      s += item.ColumnName+"|"; 
     } 

     Console.WriteLine(s); 
     Console.WriteLine("-----------------------------------------"); 
     string j = "|"; 
     foreach (DataRow item in m.Rows) 
     { 
      foreach (object ob in item.ItemArray) 
      { 
       j += ob.ToString()+"|"; 
      } 
      Console.WriteLine(j); 
      j = "|"; 
     } 
     Console.WriteLine("-----------------------------------------"); 
    } 

    private static string MakeStringBeutiful(string str) 
    { 
     while (str.Length < 9) 
      str += " "; 
     return str; 
    } 
}

結果：

嘿，直到我得到它。你有和我一樣的東西。只要您填寫答案，輸出將只選擇該行並且不會位於右列下方 – deltu

我編輯了代碼e位並添加了結果圖片 – Reniuz

如何將我的數據表顯示爲矩陣？
