Skydda och avskydda arbetsböcker i VSTO och Aspose.Cells

För att öppna en befintlig Microsoft Excel-fil, skydda arbetsboken med struktur och Windows-egenskaper och spara filen.

Här är parallella kodsnuttar för VSTO (C#) och Aspose.Cells for .NET (C#) som visar hur man skyddar en arbetsbok.

VSTO

Skydda Arbetsbok

 //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();

Avskydda Arbetsbok

  //Unprotect the workbook specifying its password.

  excelApp.ActiveWorkbook.Unprotect("007");

Aspose.Cells

Skydda Arbetsbok

 //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");

Avskydda Arbetsbok

 //Unprotect the workbook specifying its password.

  workbook.Unprotect("007");
