WMI in a webservice

[J]

Hello,

I'm trying to create a webservice that will return a list of all
printers on the machine that is running the webservice. I was hoping to do
this via WMI and System.Management.

But when I'm trying to create the webservice in .NET and I add the following
line

using System.Management

I get the error "The type or namespace name does not exist in the class or
namespace 'System'.

Why am I getting this error? Am I not allowed to use a WMI in a webservice?

Thanks in Advance

You have to add the assembly to your references also.

I'm not having the error at first sight.

Did you add a reference to System.Management?

Hi,

I have had the same problem once, I do not know, because it was not
happening on the development machine, but I am speaking about a web-page,
not a webservice, but this might be the same. I added the following to my
web.config file:

---- snip ----

<configuration>

<configSections>
<sectionGroup name="system.web"/>
</configSections>
<system.web>

<compilation
defaultLanguage="c#"
debug="true"

<assemblies>
<add assembly="System.Management, Version=1.0.5000.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a, Custom=null"/>
</assemblies>

</compilation>

--- snip ---

If I used code-behind, this was not an issue.

May be, that helps!
Best regards,
