嵌套类C＃

Question

I have data that looks like this:

Series1
Image1 ImageFile1
Image2 ImageFile2
Image3 ImageFile3

Series2
Image1 ImageFile1
Image2 ImageFile2
Image3 ImageFile3
Image4 ImageFile4

Series3
Image1 ImageFile1

I was trying to store it using Lists and this class:

  private List<SeriesClass> dcm = new List<SeriesClass>();

   public class SeriesClass
    {

      public int SeriesId { get; set; }
      public int Value1 { get; set; }
      public string Value2 { get; set; }

    }
  Loop that populates the data {
   dcm.Add(new SeriesClass { Value1 = value1, Value2 = value2, SeriesId = seriesnum});
}

Obviously not including all the code. My result is something that looks like this:

Series1 Image1 ImageFile1
Series1 Image2 ImageFile2
Series1 Image3 ImageFile3

Series2 Image1 ImageFile1
Series2 Image2 ImageFile2
Series2 Image3 ImageFile3
Series2 Image4 ImageFile4

Series3 Image1 ImageFile1

I was wondering if there is a good way to nest the classes so that SeriesID becomes like a keyfield containing the rest of the data. Like I can pull up a list of the Images under a particular Series.

I tried to do this:

public class SeriesClass
        {

      public int SeriesId { get; set; }

public class ImageClass{
      public int Value1 { get; set; }
      public string Value2 { get; set; }
          }

         }
  Loop that populates the data {
      dcm.Add(new SeriesClass { SeriesClass.ImageClass.Value1 = value1, SeriesClass.ImageClass. Value2 = value2, SeriesClass.SeriesId = seriesnum});
}

But the List.Add thing doesn't allow that.. Any help would be appreciated. I just started working with C# yesterday so this is kinda new for me. If there is a better way to do this with jagged arrays or Dictionary or something I'd be up for that too.

Thanks :)

I believe you need to use a Dictionary. Dictionary can use the id as a key and a list as values.

   private Dictionary<Integer,List<SeriesClass>> dict= new Dictionary<Integer,List<SeriesClass>>();

   public class SeriesClass
    {

      public int Value1 { get; set; }
      public string Value2 { get; set; }

    }
  Loop that populates the data {
   if ( dict.containsKey(seriesNum) ){
       dict[seriesNum].Add(new SeriesClass { Value1 = value1, Value2 = value2});
   }else{
      var list = new List<SeriesClass>();
      list.Add(new SeriesClass { Value1 = value1, Value2 = value2} );
      dcm.Add(seriesNum, list);
   }
}

I havent tested the code so there might be syntax mistakes but I hope you get the gist. TryGet might be better instead of using containsKey.
