Query a collection using PropertyInfo object in LINQ

Question

I have a method with a signature like this

void RefreshMethod(IEnumerable lst, string propertyName) where T:class
{
   Type type = typeof(T         


        

Answer 1

You can lookup the property-value using property.GetValue(anObjectOfTypeT, null).

So something like:

var refreshedList =  lst.Where(l => ((int)(property.GetValue(l, null)) < 0).ToList();

This assumes the property will always be of type int though.
