Proteger y Desproteger Libros de Trabajo en VSTO y Aspose.Cells

Para abrir un archivo de Microsoft Excel existente, proteger el libro con atributos de estructura y de Windows y guardar el archivo.

A continuación se muestran fragmentos de código paralelos para VSTO (C#) y Aspose.Cells for .NET (C#) que muestran cómo proteger un libro.

VSTO

Proteger libro

 //Instantiate the Application object.

   Excel.Application excelApp = Application;

//Excel.Application excelApp = Application;

//Specify the template excel file path.

  string myPath = "MyBook.xls";

//Open the excel file.

excelApp.Workbooks.Open(myPath, Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value,

            Missing.Value, Missing.Value);

//Protect the workbook specifying a password with Structure and Windows attributes.

  excelApp.ActiveWorkbook.Protect("007", true, true);

//Save the file.

  excelApp.ActiveWorkbook.Save();

//Quit the Application.

  excelApp.Quit();

Desproteger libro

  //Unprotect the workbook specifying its password.

  excelApp.ActiveWorkbook.Unprotect("007");

Aspose.Cells

Proteger libro

 //Specify the template excel file path.

   string myPath = "Book1.xls";

//Instantiate a new Workbook.

//Open the excel file.

   Workbook workbook = new Workbook(myPath);

//Protect the workbook specifying a password with Structure and Windows attributes.

   workbook.Protect(ProtectionType.All, "007");

//Save As the excel file.

   workbook.Save("MyBook.xls");

Desproteger libro

 //Unprotect the workbook specifying its password.

  workbook.Unprotect("007");
