## ContentTypePropertyCollection class

A collection of [`ContentTypeProperty`](/cells/python-net/aspose.cells.properties/contenttypeproperty) objects that represent additional information.



The ContentTypePropertyCollection type exposes the following members:

### Properties
| Property | Description |
| :- | :- |
| [capacity](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/capacity) | Gets or sets the number of elements that the array list can contain. |


### Methods
| Method | Description |
| :- | :- |
| [`add(self, name, value)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/add/#system.string-system.string) | Adds content type property information. |
| [`add(self, name, value, type)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/add/#system.string-system.string-system.string) | Adds content type property information. |
| [`copy_to(self, array)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/copy_to/#list) | Copies the entire array list to a compatible one-dimensional array list, starting at the beginning of the target array list. |
| [`copy_to(self, index, array, array_index, count)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/copy_to/#int-list-int-int) | Copies a range of elements from the array list to a compatible one-dimensional array list, starting at the specified index of the target array list. |
| [`index_of(self, item, index)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/index_of/#aspose.cells.properties.contenttypeproperty-int) | Searches for the specified object and returns the zero-based index of the first occurrence within the range of elements in the array list that extends from the specified index to the last element. |
| [`index_of(self, item, index, count)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/index_of/#aspose.cells.properties.contenttypeproperty-int-int) | Searches for the specified object and returns the zero-based index of the first occurrence within the range of elements in the array list that starts at the specified index and contains the specified number of elements. |
| [`last_index_of(self, item)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/last_index_of/#aspose.cells.properties.contenttypeproperty) | Searches for the specified object and returns the zero-based index of the last occurrence within the entire array list. |
| [`last_index_of(self, item, index)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/last_index_of/#aspose.cells.properties.contenttypeproperty-int) | Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the array list that extends from the first element to the specified index. |
| [`last_index_of(self, item, index, count)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/last_index_of/#aspose.cells.properties.contenttypeproperty-int-int) | Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the array list that contains the specified number of elements and ends at the specified index. |
| [`get(self, name)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/get/#system.string) | Gets the content type property by the property name. |
| [`binary_search(self, item)`](/cells/python-net/aspose.cells.properties/contenttypepropertycollection/binary_search/#aspose.cells.properties.contenttypeproperty) | Searches the entire sorted array list for an element using the default comparer and returns the zero-based index of the element. |



### Example 


```python
from aspose.cells import Workbook

# Instantiating a Workbook object
workbook = Workbook()
# Add a new property.
workbook.content_type_properties.add("Admin", "Aspose", "text")
# Save the Excel file
workbook.save("book1.xlsm")

```
