備註

此建構子搜尋組合中嵌入的資源，該資源定義了參數 t 所指定的類型。建構子搜尋一個名為 namespace.classname.bmp的資源，其中命名空間是包含參數所指定 t 類別定義的命名空間。例如，若 ControlA 位於 AssemblyA.dll的命名空間 A，則建構子會搜尋 AssemblyA.dll 一個名為 NamespaceA.ControlA.bmp的資源。

備註

此建構子搜尋組合中嵌入的資源，該資源定義了參數 t 所指定的類型。建構子搜尋名為 namespace.name 的資源，其中命名空間是包含參數所指定 t 類別定義的命名空間。例如，假設 ControlA 是 AssemblyA.dll 中 NamespaceA 中的一個類別，而你將「MyBitmap.bmp」傳給參數 name 。接著建構子會搜尋 AssemblyA.dll 一個名為 NamespaceA.MyBitmap.bmp的資源。
