  1. Include the namespace in your class file
  2. Create Diagram class instance.
  3. Access the first page of the diagram.
  4. Add text in the page.
  5. Use Save method to save the diagram as VDX file.

System Requirements

Just make sure that system have Microsoft Windows or a compatible OS with .NET Framework, .NET Core, Windows Azure, Mono Platforms as well as development environment like Microsoft Visual Studio.

  • Install from command line as nuget install Aspose.Diagram or via Package Manager Console of Visual Studio with Install-Package Aspose.Diagram.
  • Alternatively, get the offline MSI installer or all DLLs in a ZIP file from downloads

Following source code shows how to create a VDX file using C#.

// Create Diagram class instance.
Diagram diagram = new Diagram();

// Access the first page of the diagram.
Page page = diagram.Pages[0];

// Add Text shape.
Shape shape = page.AddText(1, 1, 1, 1, "Test text", "Calibri", "#a5a5a5", 0.25);

// Save the Diagram as .vdx file.
An Visio Programming Library capable of building cross-platform applications with the ability to generate, modify, convert, render and print VDX files. .NET Visio API not only convert between spreadsheet formats, it can also render Visio files as images, VDX, HTML and more, thus making it a perfect choice to exchange documents in industry-standard formats.
