Question

As a simple example, I have an xml file with a list of names of classes which actually carry out the work and all implement interface IDoWork with a method Process().

I loop through the items in the xml file.
How do I actually dynamically assign the class to the interface from a string name?
e.g.

var IDoWork = new "DoWorkType1"();
IDoWork.Process();

<work>
  <item id="DoWorkType1">
  </item>
  <item id="DoWorkType2">
  </item>
</work>

I want to achieve a plugin type architecture, except the plugin isn’t at an assembly level only a class level within my program.

Answer 1

Type t = Type.GetType("DoWorkType1");
IDoWork idw = (IDoWork)Activator.CreateInstance(t);
idw.Process();
