Comentários

Esse construtor pesquisa um recurso inserido no assembly que define o tipo especificado pelo t parâmetro . O construtor pesquisa um recurso chamado namespace.classname.bmp, em que namespace é o namespace que contém a definição da classe especificada pelo t parâmetro . Por exemplo, se ControlA estiver no NamespaceA no AssemblyA.dll, o construtor pesquisa AssemblyA.dll um recurso chamado NamespaceA.ControlA.bmp.

Esse construtor pesquisa um recurso inserido no assembly que define o tipo especificado pelo t parâmetro . O construtor procura um recurso chamado namespace.name, em que namespace é o namespace que contém a definição da classe especificada pelo t parâmetro . Por exemplo, suponha que ControlA seja uma classe no NamespaceA no AssemblyA.dll e que você tenha passado "MyBitmap.bmp" para o name parâmetro . Em seguida, o construtor pesquisa AssemblyA.dll um recurso chamado NamespaceA.MyBitmap.bmp.
