Hinweise

Dieser Konstruktor sucht nach einer eingebetteten Ressource in der Assembly, die den durch den t Parameter angegebenen Typ definiert. Der Konstruktor sucht nach einer Ressource mit dem Namen namespace.classname.bmp, wobei namespace der Namespace ist, der die Definition der klasse enthält, die durch den t Parameter angegeben wird. Wenn sich beispielsweise ControlA in AssemblyA.dll in NamespaceA befindet, durchsucht der Konstruktor AssemblyA.dll nach einer Ressource mit dem Namen NamespaceA.ControlA.bmp.

Hinweise

Dieser Konstruktor sucht nach einer eingebetteten Ressource in der Assembly, die den durch den t Parameter angegebenen Typ definiert. Der Konstruktor sucht nach einer Ressource namens namespace.name, wobei namespace der Namespace ist, der die Definition der klasse enthält, die durch den t Parameter angegeben wird. Angenommen, ControlA ist eine Klasse in NamespaceA in AssemblyA.dll und Sie haben "MyBitmap.bmp" an den name Parameter übergeben. Anschließend sucht der Konstruktor AssemblyA.dll nach einer Ressource namens NamespaceA.MyBitmap.bmp.
