Question:

Convert a list into a dictionary based on key: .Net

To convert a list into a dictionary based on key with Id, Name, and so on on the list, you should select the Name and combine it into a string.

var dict = lst.ToLookup(x => x.Id)

.ToDictionary(x => x.Key, x => String.Join(", ", x.Select(y => y.Name)));

.ToList() will return the grouped list of MyData.
