Question

I used the following methods to construct Order By Expression. Original Source

It is really slick. The downside is it only works if Property is

I have, IMHO, a simpler solution:

public static IOrderedQueryable Sort(this IQueryable source, bool ascending , string sortingProperty)
{
    if (ascending)
        return source.OrderBy(item => item.GetReflectedPropertyValue(sortingProperty));
    else
        return source.OrderByDescending(item => item.GetReflectedPropertyValue(sortingProperty));
}

private static object GetReflectedPropertyValue(this object subject, string field)
{
    return subject.GetType().GetProperty(field).GetValue(subject, null);
}

The usage is:

myQueryableCollection.Sort(ascending: true, "Name")

Of course, the PropertyExist() helper is a great addition...
