This is the least lazy answer (I'm just proud of this answer :)
I don't have ReSharper, tried it before but didn't want to buy it.
I tried a class diagram but is not practical at all because the hierarchy diagram spans the world 3 times over and my laptop's screen does not have infinite width.
So my natural and easy solution was to write some Windows Forms code to iterate over the types in an assembly and use reflection to add nodes to a tree view, as follows:
please assume you have a text box, a tree view and other things needed on a form in which this code runs
//Go through all the types and either add them to a tree node, or add a tree
//node or more to them depending whether the type is a base or derived class.
//If neither base or derived, just add them to the dictionary so that they be
//checked in the next iterations for being a parent a child or just remain a
//root level node.
var types = typeof(TYPEOFASSEMBLY).Assembly.GetExportedTypes().ToList();
Dictionary<Type, TreeNode> typeTreeDictionary = new Dictionary<Type, TreeNode>();
foreach (var t in types)
{
var tTreeNode = FromType(t);
typeTreeDictionary.Add(t, tTreeNode);
//either a parent or a child, never in between
bool foundPlaceAsParent = false;
bool foundPlaceAsChild = false;
foreach (var d in typeTreeDictionary.Keys)
{
if (d.BaseType.Equals(t))
{
//t is parent to d
foundPlaceAsParent = true;
tTreeNode.Nodes.Add(typeTreeDictionary[d]);
//typeTreeDictionary.Remove(d);
}
else if (t.BaseType.Equals(d))
{
//t is child to d
foundPlaceAsChild = true;
typeTreeDictionary[d].Nodes.Add(tTreeNode);
}
}
if (!foundPlaceAsParent && !foundPlaceAsChild)
{
//classHierarchyTreeView.Nodes.Add(tn);
}
}
foreach (var t in typeTreeDictionary.Keys)
{
if (typeTreeDictionary[t].Level == 0)
{
classHierarchyTreeView.Nodes.Add(typeTreeDictionary[t]);
}
}
StringBuilder sb = new StringBuilder();
foreach (TreeNode t in classHierarchyTreeView.Nodes)
{
sb.Append(GetStringRepresentation(t, 0));
}
textBox2.Text = sb.ToString();
