Type.GetTypeFromProgID 方法

定义

命名空间:

System

程序集:

System.Runtime.dll

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 null。
GetTypeFromProgID(String, Boolean)	获取与指定程序标识符（ProgID）关联的类型，指定在加载类型时发生错误时是否引发异常。
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，如果在加载类型时遇到错误，则返回 null。
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，指定在加载类型时出错时是否引发异常。

GetTypeFromProgID(String)

Source:

Type.cs

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 null。

public:

Public Shared Function GetTypeFromProgID (progID As String) As Type

参数

progID

String

要获取的类型 ProgID。

返回

Type

与指定的 ProgID 关联的类型（如果 progID 是注册表中的有效条目，并且类型与之关联）;否则，null。
