保护和取消保护工作簿

保护工作簿

要打开现有的 Microsoft Excel 文件,请保护工作簿的结构和 Windows 属性,并保存文件。

以下是 VSTO(C#,VB)和 Aspose.Cells for .NET(C#,VB)的并行代码片段,用于显示如何保护工作簿。

VSTO

C#

 .......

using Microsoft.VisualStudio.Tools.Applications.Runtime;

using Excel = Microsoft.Office.Interop.Excel;

using Office = Microsoft.Office.Core;

using System.Reflection;

.......

//Instantiate the Application object.

Excel.Application excelApp = new Excel.ApplicationClass();

//Specify the template excel file path.

string myPath = @"d:\test\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();

Aspose.Cells for .NET

C#

 .......

using Aspose.Cells;

.......


//Specify the template excel file path.

string myPath = @"d:\test\MyBook.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(@"d:\test\MyBook.xls");

取消保护工作簿

要取消保护工作簿,请使用以下代码行,适用于 VSTO(C#,VB)和 Aspose.Cells for .NET(C#,VB)。

VSTO

C#

 //Unprotect the workbook specifying its password.

excelApp.ActiveWorkbook.Unprotect("007");

Aspose.Cells for .NET

C#

 //Unprotect the workbook specifying its password.

workbook.Unprotect("007");
