how to create a list of type obtained from reflection

Question

I have a code which looks like this :

Assembly assembly = Assembly.LoadFrom(\"ReflectionTest.dll\");
Type myType = assembly.GetType(@\"ReflectionTest.TestObject\

You need MakeGenericType method:

var argument = new Type[] { typeof(myType) };
var listType = typeof(List<>); 
var genericType = listType.MakeGenericType(argument); // create generic type
var instance = Activator.CreateInstance(genericType);  // create generic List instance

var method = listType.GetMethod("Add"); // get Add method
method.Invoke(instance, new [] { argument }); // invoke add method 

Alternatively you can cast your instance to IList and directly use Add method.Or use dynamic typing and don't worry about casting:

dynamic list = Activator.CreateInstance(genericType);
list.Add("bla bla bla...");
