我正在尝试使用 QuickGraph 构建包含记录顶点的 Graphviz 图。到目前为止，我有这个：

var algo = new GraphvizAlgorithm<Entity, EntityEdge>(this);
algo.CommonVertexFormat.Shape = GraphvizVertexShape.Record;
algo.CommonVertexFormat.Style = GraphvizVertexStyle.Filled;
algo.FormatVertex += new FormatVertexEventHandler<Entity>(FormatVertex);

private void FormatVertex(object sender, FormatVertexEventArgs<Entity> e) {
    Entity ent = e.Vertex;
    GraphvizRecord rec = new GraphvizRecord();

    GraphvizRecordCell rootCell = new GraphvizRecordCell();
    rootCell.Text = ent.ClassName + "\\n" + ent.TargetName;

    var inputs = ent.GetUniqueInputNames();

    foreach (string input in inputs) {
        GraphvizRecordCell cell = new GraphvizRecordCell();
        cell.Text = input;
        cell.Port = input;
        rootCell.Cells.Add(cell);
    }

    rec.Cells.Add(rootCell);

    e.VertexFormatter.Record = rec;
}

但是，当我生成图形时，顶点显示的是标签而不是记录。我究竟做错了什么？

这是点输出。

根单元格中缺少详细信息，特别是对象方法的名称。我猜dot输出线

0 [label="EntityMap.Entity"];

...真的应该是：

0 [label="<EnableMotion> EntityMap.Entity"];

（......我猜他们不应该都被命名EntityMap.Entity？）

我无法真正说出在您的程序中何处引入了边缘，但似乎边缘是基于与顶点不同的信息呈现的。

dot手动运行( dot foo.dot -Tpng -o foo.png) 可能会为您提供更多信息性错误/警告消息。
