How do I use reflection to get properties explicitly implementing an interface?

Question

More specifically, if I have:

public class TempClass : TempInterface
{

    int TempInterface.TempProperty
    {
        get;
        set;
    }
    int Temp

This seems a bit painful for no apparent reason!

My solution is for the case where you know the name of the property you are looking for and is pretty simple.

I have a class for making reflection a bit easier that I just had to add this case to:

public class PropertyInfoWrapper
{
    private readonly object _parent;
    private readonly PropertyInfo _property;

    public PropertyInfoWrapper(object parent, string propertyToChange)
    {
        var type = parent.GetType();
        var privateProperties= type.GetProperties(BindingFlags.NonPublic | BindingFlags.Instance);

        var property = type.GetProperty(propertyToChange) ??
                       privateProperties.FirstOrDefault(p => UnQualifiedNameFor(p) == propertyName);

        if (property == null)
            throw new Exception(string.Format("cant find property |{0}|", propertyToChange));

        _parent = parent;
        _property = property;
    }

    private static string UnQualifiedNameFor(PropertyInfo p)
    {
        return p.Name.Split('.').Last();
    }

    public object Value
    {
        get { return _property.GetValue(_parent, null); }
        set { _property.SetValue(_parent, value, null); }
    }
}

You cant just do == on name because explicitly implemented properties have fully qualified names.

GetProperties needs both the search flags to get at private properties.
