I want to add functionality to sort data, by getting the string of the sort column from the Angular frontend. Here follows a short scenario.

The database model of ObjectA : Entity, IAggregateRoot. ObjectA has simple elements like Id and Name, but also has an extra object ObjectB. ObjectB has simple elements like Id and Name, but also has an extra object ObjectC, which only has simple objects Id and Name.

ObjectA: 
 Id: Guid,
 Name: String,
 ObjectB: 
 Id: Guid,
 Name: String,
 ObjectC: 
 Id: Guid,
 Name: String,
 
 

The model that is given to the frontend is flattened with only important elements:

ObjectA: 
 Id: Guid,
 Name: String,
 ObjectBName: String,
 ObjectCName: String

Now, a list of ObjectA is displayed, and I want to add sorting on it. I receive the element name (string) from the frontend to sort on, e.g. id. This sort is easily done in the backend by a Linq query like:

return objectAList.OrderBy(x => GetPropertyToSort(x, orderByString));

With the function GetPropertyToSort():

private string GetPropertyToSort(object obj, string orderBy)
 
 var prop = obj.GetType().GetProperty(char.ToUpper(orderBy[0]) + orderBy.Substring(1));
 var propValue = prop.GetValue(obj)?.ToString();
 return propValue;
 

But how can sorting by another object element, e.g. objectCName, be achieved by receiving only the flattened string value (which is actually the element ObjectA.ObjectB.ObjectC.Name)?
