properties

Hi everyone,
I have a class which has primitive type properties and also has types like List<> of something.
At this code:

string[] colums = typeof(T).GetProperties().Select(c => c.Name).ToArray();
foreach (var col in colums)
{
 var tc=  typeof(C).GetProperties().Select(c => c.Name).ToArray();
 var tp = col.GetType();
 var value = typeof(T).GetProperty(col).GetValue(item, null) ?? string.Empty;

 

}

I can get the values like this.But when it is List<> i cant.Is there any way to understand if property is List<> of something?
