Syntaxe

'Déclaration
Public ReadOnly Default Property Item ( _
    index As Object _
) As TaskInfo

public TaskInfo this [
    Object index
] { get; }

public:
property TaskInfo^ default [Object^] {
    TaskInfo^ get (Object^ index);
}

/** @property */
public TaskInfo get_Item (Object index)

Paramètres

index
The name, ID, or index of the TaskInfo to retrieve from the collection.

Valeur de propriété

The TaskInfo object.

Notes

If the call to the Contains method returns true, you can access the specified element in the collection by using the syntax TaskInfos[index]. However, if the call to Contains method returns false, this property throws an exception. In C#, this property is the indexer for the TaskInfos class.

Exemple

The following code example retrieves an item from the collection using two methods. The first method uses the tInfos[0] syntax to retrieve the entire object located in the first position of the collection and place it in the tInfo object. You can now retrieve all properties from the tInfo object as usual. The second method demonstrates how to retrieve a specific property from the first object in the collection.

Sample Output:

The task ID of the first provider is: {8FE4A9F8-D077-436B-9B00-C1EEAEFAFE55}
