使用 .NET 即时生成 visio 图

Question

如果我有客户端应用程序、服务和数据库的列表，是否有生成架构的 visio 图的好方法（具有不错的布局）？我原以为会有一种体面的方法来即时生成它。

Answer 1

GitHub上有VisioAutomation。如果您安装了 Visio，它可以自动生成图表。如果您可以将所需的图表建模为有向图，那么它可以自动为您布局图表（使用 MSAGL）。

这是一个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);

然后画出来：

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

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