JScript supporta l'utilizzo di proprietà indicizzate, ma non la dichiarazione di nuove proprietà.

Osservazioni

If the call to the Contains method returns true, you can access the specified element in the collection 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 Connections class.

Esempi

The following code sample retrieves an item from the collection using two methods. The first method uses the conns[0] syntax to retrieve the whole object located in the first position of the collection and put it in the myConnMgr variable. You can now retrieve all properties from the myConnMgr as usual. The second method retrieves a specific property from the first object in the collection using the conns[0].<property> syntax.

Sample Output:

The ID of the first connection info is: {B52C0D78-5402-4544-BFEC-2BE203900C91}

The Name of the first connection info is: Create_Execute_Process_Dest.sql
