Web服务无法调用注册表GetValue函数? [英] Webservice can't call Registry GetValue function?

问题描述

大家好！

我使用Web服务来获取并返回注册表值.
有关更多详细信息，请参见以下示例:

Hi everyone!

I use a webservice in order to get and return Registry value.
For explicit more, example follow:

RegistryKey regKey = Registry.CurrentUser.OpenSubKey("Software\\Yahoo\\Pager");
string sUserName = regKey.GetValue("Yahoo! User ID").ToString();
regKey.Close();

在Winform应用程序中，我可以轻松地获得"sUserName"变量，但无法在Web服务上获取它，它引发异常:对象引用未设置为对象的实例"

专家可以在这方面帮助我吗?

In winform application, I can get ''sUserName'' variable easily, but I can''t get it on a webservice, it throws exception: "Object reference not set to an instance of an object"

Experts can help me in this regard?
Thanks so much in advance!

推荐答案

您似乎有权限问题.
在此处查看一下 [

It looks like you might be having permission issues.
Have a look here[^].

我相信IIS使用其他帐户，例如ASP.NET帐户.
从您的代码中，我看到的是当前用户的it查询.
因此基本上，当前用户将是ASP.NET帐户.

I believe IIS use other account like ASP.NET account.
from your code what I see is the it query on the current user.
so basically the current user will be the ASP.NET account.

RegistryKey regKey = Registry.CurrentUser.OpenSubKey("Software\\Yahoo\\Pager");

将始终返回null.
尝试使用ASP.NET的假冒功能.

will always return null.
try to use the Impersonation feature of ASP.NET.

我已经尝试了所有像这样的方式:设置完全控制，设置文件夹权限，设置注册表权限...等等，但我没有成功.
您可以看到演示项目，其网址为:"http://www.mediafire.com/?y55igzyhc5ob7wk".我用Visual Studio 2005构建了它.Debugging-(F5)可以，但是不能通过IIS在站点上运行.

其他任何方式，请帮我，tks！

I have tried all ways like: set Full control, set Folder Permissions, set Registry Permissions... etc but i don''t successful.
You can see demo project follow: ''http://www.mediafire.com/?y55igzyhc5ob7wk''. I built it by Visual Studio 2005. Debugging-(F5) is ok, but run it as a site through IIS is not successful.

Other any way, please help me, tks!
