Syntaxe
'Déclaration
Public ReadOnly Default Property Item ( _

'Utilisation
Dim instance As DtsErrors

JScript prend en charge l'utilisation de propriétés indexées, mais pas la déclaration de nouvelles propriétés.
Paramètres
- index
Type : System. . :: . .Object
The error number, index, or description of the DtsError object to return.
Valeur de propriété
Type : Microsoft.SqlServer.Dts.Runtime. . :: . .DtsError
A DtsError object.
Notes
If the call to the Contains method returns true, you can access the specified element in the collection by using the syntax Connections[index]. If the Contains method returns false, this property throws an exception. In C#, this property is the indexer for the DtsErrors class.
Exemples
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.
