Aspose.Cells - Åtkomst till dokumentegenskaper
Utvecklare kan använda Index eller Namn av egenskapen för att få en specifik egenskap från en custom_properties samling som demonstreras nedan i exemplet.
Ruby-kod
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 - Lägg till egna egenskaper
För att lägga till egna dokumentegenskaper med Aspose.Cells Java för Ruby, anropa metoden add_custom_property i modulen Document.
Ruby-kod
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 - Ta bort egna egenskaper
För att ta bort egna dokumentegenskaper med Aspose.Cells Java för Ruby, anropa metoden remove_custom_property i modulen Document.
Ruby-kod
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
