The request failed with HTTP status 401: Unauthorized

02-17-06, 03:55 AM

I have a WebService in localhost, and the set in the web.config is

<add key="WebReference.Service"
value="http://localhost/HealthService/Service.asmx"/>
and the code to refer the WebService is
WebReference.Service wsHealth = new WebReference.Service();

But when I use code to execute a function in the webservice, like
ds =(System.Data.DataSet)wsHealth.GetSchools_Zip(txtZ ip1.Text);

it result into an error:
The request failed with HTTP status 401: Unauthorized

I have type the web service URL into browse, it execute OK, but it can't
call in program.

How can I do?

Sounds like IIS is using integrated authentication for that application.
Your browser supplies the credentials of the logged in user, whereas the
web service proxy does not. You can either change the code for your web service
proxy to 1) hard code the credntials, 2) prompt the user and pass those credentials,
or 3) use the current logged in user's credentials. Check out the Credentials
property of teh web service proxy. Set it to CredentialCache.DefaultCredentials
to get the thrid behavior I listed. For the first or second, use an instance
of the System.Net.NEtworkCredential class.

Thanks,
I use the method 3, and my problem is gone away.
But I have some question:

I have set virtual directory of the WebService to anonymous, why it need
Credentials ?
