Sintaxis

'Declaración
Public ReadOnly Default Property Item ( _
    index As Object _
) As Configuration

public Configuration this [
    Object index
] { get; }

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

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

Parámetros

index
The name, description, ID, or index of the Configuration object to return.

Valor de propiedad

A Configuration object.

Notas

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

Ejemplo

The following code example uses the Contains method to see if item syntax is available. If true, the code example uses the item syntax of p.Configurations[0].Name to get the name of the configuration located in the first position of the collection, index position 0.
