Query a collection using PropertyInfo object in LINQ

c#, linq, reflection

Solution

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.

Problem

I have a method with a signature like this ``` void RefreshMethod<T>(IEnumerable<T> lst, string propertyName) where T:class { Type type = typeof(T); PropertyInfo property = type.GetProperties().Single(u => u.Name == primaryKeyProperty); //query goes here } ``` Now i want to query that collection for getting all the values whose propertyName < 0 In a simple scenario it would be as easy as this ``` lst.where(u=>u.ID<0) ``` But here i don't have that ID property but have corresponding "PropertyInfo" object. How should i acheive this. kindly guide
