Class name as string in defining a collection in c#

Question

I have class name as string that I got using TYPE

Type type = myvar.GetType();  
string _className = type.ToString(); // getting the class name

My question is how to use this string _className here in the code below?

var data = this.ItemsSource as ObservableCollection<**_className**>()[2];

Here ItemsSource is generic.

Thanks in advance.

You can do that using reflection and the Activator.CreateInstance method:

Type type = myvar.GetType();  
string className = type.ToString(); 
Type genericType = Type.GetType(className);
Type observableCollectionType = typeof(ObservableCollection<>);
Type constructedType = observableCollectionType.MakeGenericType(genericType);
var constructedInstance = Activator.CreateInstance(constructedType);
