Commenti

Questo costruttore cerca una risorsa incorporata nell'assembly che definisce il tipo specificato dal t parametro . Il costruttore cerca una risorsa denominata namespace.classname.bmp, dove namespace è lo spazio dei nomi contenente la definizione della classe specificata dal t parametro . Ad esempio, se ControlA è in NamespaceA in AssemblyA.dll, il costruttore cerca AssemblyA.dll una risorsa denominata NamespaceA.ControlA.bmp.

Questo costruttore cerca una risorsa incorporata nell'assembly che definisce il tipo specificato dal t parametro . Il costruttore cerca una risorsa denominata namespace.name, in cui namespace è lo spazio dei nomi contenente la definizione della classe specificata dal parametro t. Si supponga, ad esempio, che ControlA sia una classe in NamespaceA in AssemblyA.dll e che sia stato passato "MyBitmap.bmp" al name parametro . Il costruttore cerca quindi AssemblyA.dll una risorsa denominata NamespaceA.MyBitmap.bmp.
