web services - Reading WebService Wsdl using c#.Net -

we have soap based web service , able read wsdl when type in url in browser. sit behind proxy in our network not blocking , able read wsdl using browser.but when enter url in browser http://ist.services/coreservices/coreservices?wsdl asks username , password not same windows credentials. when enter username , password shared dev team , returns wsdl page. please note webservice developed , deployed on java based server.

how do same in c#.net code , how pass security crednetials in discoveryclientprotocol? tried below code works webservices doesn't ask security credentials.

  // specify url discover.         string sourceurl = "http://ist.services/coreservices/coreservices?wsdl";          string outputdirectory = "c:\\temp";          discoveryclientprotocol client = new discoveryclientprotocol();         var credentials = new networkcredential("sunuser1", "xxxxxxx", "");          webproxy proxy = new webproxy("http://proxy.bingo:8000/", true) { credentials = credentials };             client.credentials = credentials;         // use default credentials access url being discovered.         //client.credentials = credentials;//credentialcache.defaultcredentials;         client.proxy = proxy;         string discovermode = "discoverany";         string resolvemode = "resolveall";         try         {             discoverydocument doc;             // check see if whether user wanted read in existing discovery results.             if (discovermode == "readall")             {                 discoveryclientresultcollection results = client.readall(path.combine("c:\\temp", "results.discomap"));                 //savemode.value = "nosave";             }             else             {                 // check see if whether user wants capability discover kind of discoverable document.                 if (discovermode == "discoverany")                 {                     doc = client.discoverany(sourceurl);                 }                 else                 // discover discovery documents, might contain references other types of discoverable documents.                 {                     doc = client.discover(sourceurl);                 }                 // check see whether user wants resolve possible references supplied url.                 if (resolvemode == "resolveall")                     client.resolveall();                 else                 {                     // check see whether user wants resolve references nested more 1 level deep.                     if (resolvemode == "resolveonelevel")                         client.resolveonelevel();                     else                         console.writeline("empty");                 }             }         }         catch (exception e2)         {             //discoveryresultsgrid.columns.clear();             //status.text = e2.message;             console.writeline(e2.message);         }         // if documents discovered, display results in data grid.         if (client.documents.count > 0)             console.writeline(client);      }     } 

since code didn't me , opened fiddler trace http calls when manual read wsdl in browser , see takes credentials entered "authorization: basic cgdfddsfdfsdsfdsgsgfg=" . in fiddler see 3 calls responses 401,302 , 200. in c#.net code don't 200 response , throws me 404 error.

i further debugged , in httpresponse of client object see flag status invocation_flags_initialized | invocation_flags_need_security

so looks need pass credentials security credentials rather network credentials.

the below code has fixed issue.

        credentialcache mycredentialcache = new credentialcache { { new uri(sourceurl),                 "basic", networkcredential } };          discoveryclientprotocol.allowautoredirect = true;         discoveryclientprotocol.credentials = mycredentialcache;
