索引的System.FormatException问题

Question

我有一套相当长的代码，用于排序气候数据。不过，我目前正面临着其中的代码将引发System.FormatException的问题给我的错误解释：

型“System.FormatException”未处理的异常发生在 mscorlib.dll中

更多信息：索引（从零开始）必须大于或等于零且小于参数列表的大小。

有谁能告诉我为什么我得到这个错误？

         var ws1 = new ClimateRecord() 
         {

      "Month/Year", "WS", "AF", "Rain", "Sun", "T-Max", "T-Min"); 

     foreach (var record in data) Console.WriteLine(record); 
    } 

上面的部分是在异常被调用。特别是Console.WriteLine部分。

 static void Main(string[] args) 
     { 
      var climateData = LoadData(); 

      Console.WriteLine("Printing all data: "); 
      PrintData(climateData); 

      Console.WriteLine("\n\nPrinting Station 1 data:"); 
      PrintData(climateData.Where(r => r.StationId == 1)); 

      Console.WriteLine("\n\nPrinting Station 2 data:"); 
      PrintData(climateData.Where(r => r.StationId == 2)); 

      Console.WriteLine("\n\nPrinting Station 1 data ordered by rainfall descending:"); 
      PrintData(climateData.Where(r => r.StationId == 1).OrderBy(r => r.RainFall * -1)); 
     } 
    } 
}

东西丢失，请参阅???：

Console.WriteLine("{0,15}{1,4}{2,8}{3,8}{4,8}{5,8}{6,8}{7,8}", 
      "Month/Year", "WS", "AF", "Rain", "Sun", "T-Max", "T-Min", "???");
