MethodBase.IsSpecialName Proprietà

Definizione

Spazio dei nomi:

System.Reflection

Assembly:

System.Runtime.dll

Origine:

MethodBase.cs

Ottiene un valore che indica se questo metodo ha un nome speciale.

public:
 property bool IsSpecialName { bool get(); };

public bool IsSpecialName { get; }

member this.IsSpecialName : bool

Public ReadOnly Property IsSpecialName As Boolean

Valore della proprietà

Boolean

true se questo metodo ha un nome speciale; in caso contrario, false.

Esempio

In questo esempio viene illustrato un uso di IsSpecialName per filtrare i membri interni o privati fuori da un elenco.

Il SpecialName bit è impostato sui membri del flag trattati in modo speciale da alcuni compilatori, ad esempio le funzioni di accesso delle proprietà e i metodi di overload degli operatori.
