在Ruby中管理文档属性

Aspose.Cells - 访问文档属性

开发人员可以使用该示例中下面演示的custom_properties集合的Index或Name来获取特定属性。

Ruby 代码

 def get_properties()

    data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'



    # Instantiating a Workbook object by excel file path

    workbook = Rjb::import('com.aspose.cells.Workbook').new(data_dir + 'Book1.xls')

    # Retrieve a list of all custom document properties of the Excel file

    custom_properties = workbook.getWorksheets().getCustomDocumentProperties()

    # Accessng a custom document property by using the property index

    puts "Property By Index: " +  custom_properties.get(1).to_string

    # Accessng a custom document property by using the property name

    puts "Property By Name: " + custom_properties.get("Publisher").to_string

end

Aspose.Cells - 添加自定义属性

要在Ruby中使用Aspose.Cells Java添加自定义文档属性，请调用Document模块的add_custom_property方法。

Ruby 代码

 def add_custom_property()

    data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'



    # Instantiating a Workbook object by excel file path

    workbook = Rjb::import('com.aspose.cells.Workbook').new(data_dir + 'Book1.xls')

    # Retrieve a list of all custom document properties of the Excel file

    custom_properties = workbook.getWorksheets().getCustomDocumentProperties()

    # Adding a custom document property to the Excel file

    custom_properties.add("Publisher", "Aspose")

    # Save the document in PDF format

    workbook.save(data_dir + "Add_Property.xls")

    puts "Added custom property successfully."

end   

Aspose.Cells - 移除自定义属性

要在Ruby中使用Aspose.Cells Java移除自定义文档属性，请调用Document模块的remove_custom_property方法。

Ruby 代码

 def remove_custom_property()

    data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'



    # Instantiating a Workbook object by excel file path

    workbook = Rjb::import('com.aspose.cells.Workbook').new(data_dir + 'Book1.xls')

    # Retrieve a list of all custom document properties of the Excel file

    custom_properties = workbook.getWorksheets().getCustomDocumentProperties()

    # Adding a custom document property to the Excel file

    custom_properties.remove("Publisher")

    # Save the document in PDF format

    workbook.save(data_dir + "Removed_Property.xls")

    puts "Removed custom property successfully."

end
