How to get Max value from Dynamic Linq ?

public Func<TSource, T> DynamicMax<TSource, T>(string fieldName, object className)
            {
                var type = typeof(TSource);
                var pe = Expression.Parameter(type, "p");
                var propertyReference = Expression.Property(pe, fieldName);
                var constantReference = Expression.Constant(className);

                return Expression.Lambda<Func<TSource, T>>
                    (Expression.IsTrue(propertyReference, constantReference), pe).Compile();
            }

What do you mean by max value? Is `T` some sort of collection? – Yuval Itzchakov Feb 04 '15 at 09:02

I also find it quite unclear - can you precize, maybe write in code - what do you exactly expect? – michalczukm Feb 04 '15 at 09:10
T is return type,. like string , guid, int ect & "object className" has property T inside the class. ex : class person has personNumber property with type string,.. – SSGeek Feb 04 '15 at 09:23
