VSTO
VSTO 允许您使用 Microsoft Visio 文件进行编程。要创建一个新的 diagram：
- 创建一个 Visio 应用程序对象。
- 使应用程序对象不可见。
- 创建一个空的 diagram。
- 添加来自 Visio 母版（模板）的形状。
- 将文件另存为 VDX。
Visio.Application vdxApp = null;
Visio.Document vdxDoc = null;
try
{
//Create Visio Application Object
vdxApp = Application;
//Make Visio Application Invisible
vdxApp.Visible = false;
//Create a new diagram
vdxDoc = vdxApp.Documents.Add("Drawing.vsd");
//Load Visio Stencil
Visio.Documents visioDocs = vdxApp.Documents;
//-----------//
Visio.Document visioStencil = visioDocs.OpenEx("sample.vss",
(short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visOpenHidden);
//Set active page
Visio.Page visioPage = vdxApp.ActivePage;
//Add a new rectangle shape
Visio.Master visioRectMaster = visioStencil.Masters.get_ItemU(@"Rectangle");
Visio.Shape visioRectShape = visioPage.Drop(visioRectMaster, 4.25, 5.5);
visioRectShape.Text = @"Rectangle text.";
//Add a new star shape
Visio.Master visioStarMaster = visioStencil.Masters.get_ItemU(@"Star 7");
Visio.Shape visioStarShape = visioPage.Drop(visioStarMaster, 2.0, 5.5);
visioStarShape.Text = @"Star text.";
//Add a new hexagon shape
Visio.Master visioHexagonMaster = visioStencil.Masters.get_ItemU(@"Hexagon");
Visio.Shape visioHexagonShape = visioPage.Drop(visioHexagonMaster, 7.0, 5.5);
visioHexagonShape.Text = @"Hexagon text.";
//Save diagram as VDX
vdxDoc.SaveAs("Drawing1.vdx");
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
//Close active document and quit
vdxDoc.Close();
vdxApp.Quit();
}
Aspose.Diagram
用Aspose.Diagram编程时，机器上不需要Microsoft Visio，可以独立于Microsoft Office自动化工作。要创建一个新的 diagram：
- 创建一个空的 diagram。
- 添加来自 Visio 母版（模板）的形状。
- 将文件另存为 VDX。
string visioStencil ="sample.vss";
// Create a new diagram
Diagram diagram = new Diagram(visioStencil);
//Add a new rectangle shape
long shapeId = diagram.AddShape(
4.25, 5.5, 2, 1, @"Rectangle", 0);
Shape shape = diagram.Pages[0].Shapes.GetShape(shapeId);
shape.Text.Value.Add(new Txt(@"Rectangle text."));
//Add a new star shape
shapeId = diagram.AddShape(
2.0, 5.5, 2, 2, @"Star 7", 0);
shape = diagram.Pages[0].Shapes.GetShape(shapeId);
shape.Text.Value.Add(new Txt(@"Star text."));
//Add a new hexagon shape
shapeId = diagram.AddShape(
7.0, 5.5, 2, 2, @"Hexagon", 0);
shape = diagram.Pages[0].Shapes.GetShape(shapeId);
shape.Text.Value.Add(new Txt(@"Hexagon text."));
//Save the new diagram
diagram.Save("Drawing1.vdx", SaveFileFormat.VDX);
