Hi Simon,
From your description, I understand that you're getting some problem when
try read connectionstring from configuration file of an Webservice
application ,correct?
As for the webservice application and code, would you provide some further
info? I've performed a simple test as below:
** add a connectionstring into webservice's main web.config such as
<connectionStrings>
<add name="ConnStr" connectionString="xxxxxxxxxxxxxxx"/>
</connectionStrings>
** add a webmethod which will return a certain connectionString via name.
e.g.
>>>>>>>>>>>
[WebMethod]
public string GetConnectionString(string name)
{
return
ConfigurationManager.ConnectionStrings[name].ConnectionString;
}
<<<<<<<<<
and I get get the connectionstring entry returned correctly. Therefore, I
wonder whether there is any particular setting difference in your
applicaiton.
Please feel free to post here if there is anything I missed.
Sincerely,
Steven Cheng

Subject: Connection strings

I have problems with connection strings. I have added new connection string
to Web.config:
<connectionStrings>
<add name="ConnStr" connectionString="xxxxxxxxxxxxxxx"/>
</connectionStrings>
Bu when I want to access the data with:
coll = ConfigurationManager.ConnectionStrings;
connStr = coll[0].ConnectionString;
connStr = coll["ConnStr"].ConnectionString;
Second line returns:
"data source=.\SQLEXPRESS;Integrated
Security=SSPI;AttachDBFilename=|DataDirectory|aspn etdb.mdf;User
Instance=true"
And the third line return null reference exception.
Why? Is it not enough to change the connectionStrings section in project
and
this should work?
Thank you
Simon
