| Add(String) [C#, VB] | Adds an item to the DataPackagePropertySet. |
| Clear | Removes all items from the property set. |
| Contains [C#, VB] | Returns a value that indicates whether a specified key-value pair exists in the DataPackagePropertySet. |
| ContainsKey [C#, VB] | Returns a value that indicates whether a specified key exists in the DataPackagePropertySet. |
| CopyTo [C#, VB] | Copies the elements of the collection to an array, starting at a particular array index. |
| First [C++, JavaScript] | Returns an iterator to enumerate the items in the property set. |
| GetView [C++, JavaScript] | Gets an immutable view of the property set. |
| HasKey [C++, JavaScript] | Indicates whether the DataPackagePropertySet object contains a specific property. |

| Remove(KeyValuePair) [C#, VB] | Removes a specific key-value pair from the DataPackagePropertySet. |
| Remove(String) [C#, VB] | Removes a specific item from the DataPackagePropertySet. |
| TryGetValue [C#, VB] | Returns a value that indicates whether a specified key exists in the DataPackagePropertySet. If an item with that key exists, the item is retrieved as an out parameter. |
Properties

| Property | Access type | Description |
|---|---|---|

Remarks
In addition to the content being shared, each instance of a DataPackage object supports a set of properties. Target apps can use these properties to learn more about the content of the DataPackage.
This class directly supports several default properties, such as a thumbnail, a title, and a description. You can also create your own custom properties by using the Insert method or one of the Add methods. Target apps can access specific properties through the Lookup or TryGetValue methods.
Collection member lists
For JavaScript, DataPackagePropertySet supports using an index to access items.
