.net call a webservice with credentials

I have some code that calls a webservice on a different server.  I think the web service is java, but I don't know.  When the webservice has no authentication, it works.  When it does have authentication, I get a 501 error.

How can I call the web service with credentials?


SearchService svc = new global::Search.SearchService();
svc.Url = svcAddress;
SearchRequest req = new SearchRequest();
SearchResponse resp = svc.search(req); //this fails when pointing at a url that needs auth

Open in new window

What kind of authentication does the web service use? You need to find if it is java or .net.
If it is windows authentication, just use UseDefaultCredentials  property:
SearchService svc = new global::Search.SearchService();
svc.Url = svcAddress;
svc.UseDefaultCredentials  = true;

I am not trying to pass default credentials, I am trying to pass credentials manually.  I believe it is java, but I can't figure it out, and there is no one to ask.

SearchService svc = new global::Search.SearchService();
svc.Credentials = new System.Net.NetworkCredential("user", "pass");
//If I DO NOT include the above line where I specify the credentials, I get this error
//The request failed with HTTP status 401: Unauthorized.

//If I DO include, I get this error
//The request failed with HTTP status 505: HTTP Version Not Supported.

svc.Url = svcAddress;
SearchRequest req = new SearchRequest();
SearchResponse resp = svc.search(req); //this fails when pointing at a url that needs auth

Also, if I go directly to the web service url in firefox, I get a login popup box.

I solved it!

Add this line and it works:
svc.PreAuthenticate = true;
