Get all the defined mappings from an AutoMapper defined mapping

I'm using Automapper 7.0 and the syntax is different now. For example,

void Dump(TypeMap map)
{
    Console.WriteLine("---------------------------------------------------------------------");
    Console.WriteLine(map.SourceType + " ==> " + map.DestinationType);
    foreach (var m in map.GetPropertyMaps())
    {
        Console.WriteLine(m.SourceMember.Name + " ==> " + m.DestinationProperty.Name);
    }
}

And then you can call it using:

Dump(Mapper.Instance.ConfigurationProvider.FindTypeMapFor(typeof(CDModel), typeof(CD)));

or if you want to dump out everything, then do like this.

foreach (var map in Mapper.Instance.ConfigurationProvider.GetAllTypeMaps())
{
    Dump(map);
}

Going along the same path as what you were doing ...

foreach( var propertMap in map.GetPropertyMaps() )
{
    var dest = propertMap.DestinationProperty.MemberInfo;
    var source = propertMap.SourceMember;
}

How exactly do you want the expressions? Are you wanting the underlying Lambas?

If so look at

propertMap.GetSourceValueResolvers()

I also find var map = Mapper.GetAllTypeMaps(); to be useful too, as you can search for the SourceType or DestinationType.
