Returns a Boolean that indicates whether the items in the collection can be accessed by using indexing without throwing an exception.

Returns
A Boolean that indicates whether the collection can be accessed by description code, error number, or index. A value of true indicates that the collection can be accessed by using the syntax DtsErrors[index]. A value of false indicates that indexing cannot be used to retrieve items from the DtsErrors collection.
Examples
The following code example creates a Send Mail task and adds it to a package. Not all of the required properties of the Send Mail task are set, so when the package runs, there are errors and warnings in the DtsErrors and DtsWarnings collections. The Contains method is used to see if the collections can be accessed using the DtsErrors[index] syntax, and if so, obtains some properties using that syntax.
