System.FormatException Problem mit einem Index

Question

Ich habe eine ziemlich lange Reihe von Code, der Klimadaten sortieren soll. Allerdings bin ich zur Zeit ein Problem gegenüber, wo der Code eine System.FormatException wirft gibt mir den Fehler Erklärung:

Eine nicht behandelte Ausnahme des Typs ‚System.FormatException‘ aufgetreten in mscorlib.dll

Zusätzliche Informationen : Index (nullbasiert) muss größer als oder gleich null und kleiner als die Größe der Argumentliste sein.

Kann mir jemand sagen, warum ich diesen Fehler bekomme?

      return String.Format("{0,-15:MMMM yyyy}{1,4}{2,8:F4}{3,8:F4}{4,8:F4}{5,8:F4}{6,8:F4}{7,8:F4}",

      var result = new List<ClimateRecord>();

         var ws1 = new ClimateRecord() 
         { 
          RecordDate = recordDate, 
          StationId = 1,

static void PrintData(IEnumerable<ClimateRecord> data)

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

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

Above Abschnitt ist, wo die Ausnahme aufgerufen wird. Insbesondere der Console.WriteLine-Teil.

 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)); 
     } 
    } 
} 

Answer 1

Etwas fehlt, sehen ???:

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", "???");
