I'm very new to C# but I have some experience in C++. There a struct array was an alternative but I don't know how to do that in C#.

// create dictionary
Dictionary<string, List<int>> items = new Dictionary<string, List<int>>();
// populate it with data from the file
foreach (string line in File.ReadAllLines(pathName)) {
   string[] data = line.Split('\t');
   List<int> list;
   if (!items.TryGetValue(data[0], out list) {
      list = new List<int>();
      items.Add(data[0], list);
   }
   list.Add(int.Parse(data[2]));
}
// get the list for a specific string
List<int> aaabb = items["aaabb"];
// sort the list
aaabb.Sort();

Is it possible?

enum MyEnum { None=0, Few=1, Some=2, Many=4, CrapLoad=8, All=128};

public static T IntToEnum < t > (int value, T defaultValue)
{
	T enumValue = (Enum.IsDefined(typeof(T), value)) ? (T)(object)value : defaultValue;
	return enumValue;
}

//Usage:

// Given the value of x, IntToEnum would return MyEnum.All because there 
// is no ordinal with the value of x.
int x = 3;
MyEnum myEnum = IntToEnum < MyEnum > (x, MyEnum.All);

// Given the value of x, IntToEnum would return MyEnum.Many because there 
// *is* an ordinal with the value of x.
x = 4;
myEnum = IntToEnum < MyEnum > (x, MyEnum.All);
