Most efficient way to get default constructor of a Type

Question

What is the most efficient way to get the default constructor (i.e. instance constructor with no parameters) of a System.Type?

I was thinking something along the lines o

Answer 1

you would want to try FormatterServices.GetUninitializedObject(Type) this one is better than Activator.CreateInstance

However , this method doesn't call the object constructor , so if you are setting initial values there, this won't work Check MSDN for this thing http://msdn.microsoft.com/en-us/library/system.runtime.serialization.formatterservices.getuninitializedobject.aspx

there is another way here http://www.ozcandegirmenci.com/post/2008/02/Create-object-instances-Faster-than-Reflection.aspx

however this one fails if the object have parametrize constructors

Hope this helps
