LogicalMethodInfo.IsAsync-Eigenschaft

Ruft einen Wert ab, der angibt, ob die durch die Instanz von LogicalMethodInfo dargestellte Methode asynchron aufgerufen wird.

Namespace: System.Web.Services.Protocols
Assembly: System.Web.Services (in system.web.services.dll)

Syntax

'Declaration
Public ReadOnly Property IsAsync As Boolean
'Usage
Dim instance As LogicalMethodInfo
Dim value As Boolean

value = instance.IsAsync

public bool IsAsync { get; }

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

/** @property */
public boolean get_IsAsync ()

public function get IsAsync () : boolean

Eigenschaftenwert

true, wenn die Methode asynchron aufgerufen wird, andernfalls false.
