Type.GetTypeFromProgID 方法

定义

获取与指定程序标识符 (ProgID) 关联的类型。

重载

GetTypeFromProgID(String)

获取与指定程序标识符 (ProgID) 关联的类型,如果在加载 Type 时遇到错误,则返回空值。

GetTypeFromProgID(String, Boolean)

获取与指定程序标识符 (ProgID) 关联的类型,指定如果在加载该类型时发生错误是否引发异常。

GetTypeFromProgID(String, String)

从指定服务器获取与指定程序标识符 (progID) 关联的类型,如果在加载该类型时遇到错误则返回空值。

GetTypeFromProgID(String, String, Boolean)

从指定服务器获取与指定程序标识符 (progID) 关联的类型,指定如果在加载该类型时发生错误是否引发异常。

GetTypeFromProgID(String)

获取与指定程序标识符 (ProgID) 关联的类型,如果在加载 Type 时遇到错误,则返回空值。

Public Shared Function GetTypeFromProgID (progID As String) As Type

参数

progID
String

要获取的类型的 ProgID。

返回

Type

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 null

属性

例外

progID 上声明的默认值为 null

注解

提供此方法是为了支持 COM。 Microsoft .NET Framework 中未使用 progid,因为它们已被命名空间的概念取代。
