I've tried a few different ways to dynamically create an object of 'unknown' type.
This is my final, simple result:
public static T Create<T>()
Type type = typeof(T);
Ok, I'm getting a little flak here.
This is just a simple example.
In my project I deal with a lot of data objects, not all know at compile time, as some classes / objects may be from other separate (dynamically loaded) assemblies, yet still within the AppDomain.
A similar implementation of the code above allows my worker class to dynamically create any data object, and populate it.
As far as code-costs go, this is a very light simple method. I'm still yet to check CPU-costs.
If anybody has reliable stats on CPU costs please let me know.
private static T From<T>(IDataReader reader, Type type)
dynamic obj = type.Assembly.CreateInstance(type.FullName);
This code did / does not work for me as the compiler moans about the "new" keyword for the template "T".
object obj = new T();
