使用.NET动态生成visio图表

Question

如果我有一个客户端应用程序，服务和数据库列表，有没有一种很好的方法来生成一个架构的visio图（具有合适的布局）？ 我本以为会有一种不错的方式来实现这一点。

GitHub上有VisioAutomation 。 如果安装了Visio，它可以自动生成图表。 如果您可以将您想要的图表建模为有向图，那么它可以自动为您布局图形（使用MSAGL）。

以下是创建有向图的基本示例

        using VACONNECT = VisioAutomation.Shapes.Connections;
        var d = new VisioAutomation.Models.DirectedGraph.Drawing();

        var basic_stencil = "basic_u.vss";
        var n0 = d.AddShape("n0", "Node 0", basic_stencil, "Rectangle");
        n0.Size = new VA.Drawing.Size(3, 2);
        var n1 = d.AddShape("n1", "Node 1", basic_stencil, "Rectangle");
        var n2 = d.AddShape("n2", "Node 2", basic_stencil, "Rectangle");
        var n3 = d.AddShape("n3", "Node 3", basic_stencil, "Rectangle");
        var n4 = d.AddShape("n4", "Node 4\nUnconnected", basic_stencil, "Rectangle");

        var c0 = d.AddConnection("c0", n0, n1, "0 -> 1", VACONNECT.ConnectorType.Curved);
        var c1 = d.AddConnection("c1", n1, n2, "1 -> 2", VACONNECT.ConnectorType.RightAngle);
        var c2 = d.AddConnection("c2", n1, n0, "0 -> 1", VACONNECT.ConnectorType.Curved);
        var c3 = d.AddConnection("c3", n0, n2, "0 -> 2", VACONNECT.ConnectorType.Straight);
        var c4 = d.AddConnection("c4", n2, n3, "2 -> 3", VACONNECT.ConnectorType.Curved);
        var c5 = d.AddConnection("c5", n3, n0, "3 -> 0", VACONNECT.ConnectorType.Curved);

然后绘制它：

        var options = new VisioAutomation.Models.DirectedGraph.MsaglLayoutOptions();

        var page = visio_app.ActivePage;
        d.Render(page,options);
