Property Value

A DtsProperties collection.

Example

The following code example creates an XMLTask. Using the Properties collection, the properties of the task are set. Using the Properties collection is the recommended way of setting properties on any task. It is not recommended that the task be cast to its equivalent class and properties set directly.
