How do I use Activator.CreateInstance to do the following please - activator

Question

I use a similar style of code many times in my application to read in records from a database
WorkoutResultsRecord is inherited from a class called BaseRecord. One of the base constructors takes a IDataReader parameter to read fields into the class (as seen below).
What I want to do is define a generic function that will do the following for any/all of my 60+ xxxRecord type classes ie I can pass in a type as a parameter and it will return the correct type of objects as a typed List. Is it possible with Activator class? I've not used it before and my results just wouldn't compile
protected List<WorkoutResultsRecord> ReadRecordList(string sql,
IDbConnection connection)
{
var results = new List<WorkoutResultsRecord>();
using (IDbCommand command = GetCommand(sql, connection))
using (IDataReader reader = command.ExecuteReader())
while (reader.Read())
results.Add(new WorkoutResultsRecord(reader));
return results;
}
My really bad, failed attempt :(
private void sfsdf(Type type)
{
List<typeof(type)> lst = new List<type>();
Activator.CreateInstance(List<typeof(type)>);
}// function

Answer 1

this should work:
private void sfsdf(Type type)
{
Type genericType = typeof(List<>).MakeGenericType(type);
System.Collections.IList theList = (IList) Activator.CreateInstance(genericType);
// do whatever you like with this list...
}
Note: as the type is known at runtime only, it's not possible for you to declare a List when you write the code, so rather, use IList interface instead, but the created object theList should be of the expected type...

Answer 2

The following is the full function with all the generics done as I wanted. This will save a lot of typing!! thanks very much
allResults = (List<WorkoutResultsRecord>)FillList(typeof(WorkoutResultsRecord),
sql, connection, new KVP("FROMDATE", fromUtf.Date),
new KVP("TODATE", endDate.AddDays(1).Date));
IList FillList(Type type,string sql,IDbConnection connection,
params KVP[] parameters)
{
Type genericType = typeof(List<>).MakeGenericType(type);
IList results = (IList)Activator.CreateInstance(genericType);
using (var command= Command(sql,connection))
{
foreach(KVP parameter in parameters)
CreateParam(command,parameter.Key,parameter.Value);
using (IDataReader reader = command.ExecuteReader())
while (reader.Read())
results.Add(Activator.CreateInstance(type,reader));
}
return results;
}
