Syntax

'Declaration
Public Default Property Item ( _
    index As Integer _
) As MimePart
'Usage
Dim instance As MimePartCollection
Dim index As Integer
Dim value As MimePart

value = instance(index)

instance(index) = value

public MimePart this [
    int index
] { get; set; }

public:
property MimePart^ default [int] {
    MimePart^ get (int index);
    void set (int index, MimePart^ value);
}

/** @property */
public MimePart get_Item (int index)

/** @property */
public void set_Item (int index, MimePart value)

JScript unterstützt die Verwendung von indizierten Eigenschaften, aber nicht die Deklaration von neuen indizierten Eigenschaften.

Parameter

• index
  Der nullbasierte Index des MimePart, dessen Wert geändert oder zurückgegeben wird.

Eigenschaftenwert

Ein MimePart.
