ToolboxBitmapAttribute-Konstruktor (Type, String)

Initialisiert ein neues ToolboxBitmapAttribute-Objekt auf Grundlage einer 16 x 16-Bitmap, die als Ressource in einer angegebenen Assembly eingebettet ist.

Namespace: System.Drawing
Assembly: System.Drawing (in system.drawing.dll)

Syntax

'Declaration
Public Sub New ( _
    t As Type, _
    name As String _
)
'Usage
Dim t As Type
Dim name As String

Dim instance As New ToolboxBitmapAttribute(t, name)

public ToolboxBitmapAttribute (
    Type t,
    string name
)

public:
ToolboxBitmapAttribute (
    Type^ t, 
    String^ name
)

public ToolboxBitmapAttribute (
    Type t, 
    String name
)

public function ToolboxBitmapAttribute (
    t : Type, 
    name : String
)

Parameter

• t
  Ein Type, dessen definierende Assembly nach der Bitmapressource durchsucht wird.

• name
  Der Name der eingebetteten Bitmapressource.

Hinweise

Dieser Konstruktor sucht in der Assembly, die den vom t-Parameter angegebenen Typ definiert, nach eingebetteten Ressourcen. Der Konstruktor sucht nach einer Ressource mit dem Namen namespace.name, wobei namespace für den Namespace steht, der die Definition der vom t-Parameter angegebenen Klasse enthält. Angenommen, es handelt sich bei ControlA um eine Klasse im in AssemblyA.dll gespeicherten NamespaceA, und Sie haben "MyBitmap.bmp" an den name-Parameter übergeben. Dann durchsucht der Konstruktor AssemblyA.dll nach einer Ressource mit dem Namen NamespaceA.MyBitmap.bmp.

Beispiel

Im folgenden Codebeispiel wird veranschaulicht, wie Sie mithilfe des ToolboxBitmapAttribute-Konstruktors StopSignControl2.bmp als Toolboxsymbol für StopSignControl2 festlegen. In diesem Beispiel wird davon ausgegangen, dass eine 16 x 16-Pixel-Bitmap mit dem Namen StopSignControl2.bmp vorhanden ist und dessen BuildAction-Eigenschaft auf EmbeddedResource festgelegt ist.
