Agregando nuevas hojas de cálculo a un libro y activando una hoja

Agregar Hojas de Cálculo y Activar una Hoja

Para los propósitos de este consejo de migración:

  1. Agregar nuevas hojas de cálculo a un archivo existente de Microsoft Excel.
  2. Llenar los datos en las celdas de cada nueva hoja de cálculo.
  3. Activar una hoja en el libro de trabajo.
  4. Guardar como archivo de Microsoft Excel.

A continuación, se muestran fragmentos de código paralelos para VSTO (C#, VB) y Aspose.Cells for .NET (C#, VB), que muestran cómo lograr estas tareas.
