static member GetTypeFromProgID : string -> Type
Public Shared Function GetTypeFromProgID (progID As String) As Type

参数

progID
String

要获取的类型的 ProgID。The ProgID of the type to get.

返回

如果 progID 是注册表中的有效项,并且有与之关联的类型,则为与指定 ProgID 关联的类型;否则为 nullThe type associated with the specified ProgID, if progID is a valid entry in the registry and a type is associated with it; otherwise, null.
