Question

How can I use reflection to create a generic List with a custom class (List<CustomClass>)? I need to be able to add values and use propertyInfo.SetValue(..., ..., ...) to store it. Would I be better off storing these List<>’s as some other data structure?

Edit:

I should have specified that the object is more like this, but Marc Gravell’s answer works still.

class Foo {     public List<string> Bar { get; set; } } 

Answer 1

class Foo {     public string Bar { get; set; } } class Program {     static void Main()     {         Type type = typeof(Foo); // possibly from a string         IList list = (IList) Activator.CreateInstance(             typeof(List<>).MakeGenericType(type));          object obj = Activator.CreateInstance(type);         type.GetProperty('Bar').SetValue(obj, 'abc', null);         list.Add(obj);     } }
