How to access at run-time the value of an IEnumerable<T>

Question

Good day all:

I'm developing a WEB API that returns a paged response to a jQuerydatatable end point. Because the code repeats itself, I encapsulated all the logic in the generic procedure below. The code works perfectly when I pass the class (entity) I want the SQL stored procedure to page. The issue is that I want to access the value of two of the properties return by the IEnumerable <T> namely TotalCount and FilteredCount which are always returned by the stored procedure

public async Task<OutgoingResponseToEndPointDatatable<T>> SendingDataBackToEndPointJqueryDatatable(OncomingEndPointDatatableRequest request, string NameOfStoredProcedure)

{

 var parameters = new StoredProcedureParameters()

 {

     PageNo = Convert.ToInt32(request.start / request.length),

     PageSize = request.length,

     SortColumn = request.Order[0].Column,

     SortDirection = request.Order[0].Dir,

     SearchValue = request.Search != null ? request.Search.Value.Trim() : ""

 };

 IEnumerable<T> outcome= await  _db.LoadPaginationSearchAndSortingStoredProcedure<T, dynamic>(storedProcedure: NameOfStoredProcedure, parameters: parameters);

How I can refer to the int values of the TotalCount and FitredCount properties return by the procedure above? I tried using var properies=trypeof(T). GetProperties but an object is return and I want to access to the int values not the object.

Answer 1

implement an interface (or base class) implemented by the sp return classes

	public interface IQueryResult
	{
		int TotalCount {get; set;}
		int FilteredCount {get; set;}
	}

then require the interface in the method definition

public T Test<T>(T p) where T: IQueryResult
{
}
