远程调用COM模拟其他用户 [英] Remote call to COM impersonating another user

问题描述

我需要使用C＃从远程计算机调用COM对象。我还需要

传递一个不同的用户ID和密码来进行通话。有没有人这样做过？

我使用Java来使用JIntegra来做这件事，但是我使用的应用程序是
需要.NET。


有什么建议吗？

I need to call a COM object from a remote machine using C#. I also need to
pass on a different userID and password to the call. Has anyone done this?
I''ve used Java to do this using JIntegra, but the application I''m using
requires .NET.

Any advice?

推荐答案

嗯，你很可能不得不通过DCOM / COM +来打电话。 />
假设你在另一台机器上设置正确，并且你想要调用的COM对象有一个

接口定义，你可以调用

GetTypeFromProgID（或GetTypeFromCLSID），使用重载将需要

a远程机器名。然后，您将通过调用Activator类上的CreateInstance创建该类型的实例

，并转换为您的

接口类型。


请注意，进行远程调用的语义不仅仅是

进行常规COM调用（激活上下文，实例化等）。


您是否已经为远程呼叫设置了对象？

Well, you are more than likely going to have to call through DCOM/COM+.
Assuming you have it set up correctly on the other machine, and you have an
interface definition for the COM object you want to call, you can call the
GetTypeFromProgID (or GetTypeFromCLSID), using the overload which will take
a remote machine name. You would then create an instance of that type
through a call to CreateInstance on the Activator class, and cast to your
interface type.

Mind you, the semantics of making a remote call are different than just
making a regular COM call (activation contexts, instancing, and the like).

Do you already have the object set up for remote calls?

它是为远程呼叫设置的 - 我可以使用
$ b远程拨打这些电话$ b JIntegra。我想我需要的是复制JIntegra的功能。我得到了

身份验证错误，这让我相信我需要机制

设置带有凭据的呼叫 - 在这种情况下是userID，密码。

It''s set up for remote calls - I am able to make these calls remotely using
JIntegra. I guess what I need is to duplicate what JIntegra does. I get
authentication errors which leads me to believe that I need the mechanism
that sets up the call with credentials - in this case userID, password.

嗯，你很可能不得不通过DCOM / COM +打电话。

假设你已经正确设置了它其他机器，你有一个你要调用的COM对象的接口定义，你可以调用

GetTypeFromProgID（或GetTypeFromCLSID），使用重载

采用远程机器名称。然后，您将通过在Activator类上调用CreateInstance来创建该

类型的实例，并将其转换为

您的界面类型。

好吧，你总是可以在客户端线程上冒充那个调用者，并且

然后通过P / Invoke层调用CoImpersonateClient API函数

（确保调用CoRevertToSelf）。

Well, you can always impersonate that caller on the client thread, and
then call the CoImpersonateClient API function through the P/Invoke layer
(make sure to call CoRevertToSelf).
