Cannot Connect to Model Manager Web Services

Hello

I can't connect to MM Web services using Web Services using C#.

Does anyone ever done something like this and can give me an example?

I made ana attempt as follows but I have an exception:

QueryService.QueryServiceClient qrsc = new QueryService.QueryServiceClient("QueryService", "http://192.168.0.2:8580/QueryService");

qrsc.ClientCredentials.UserName.UserName = "medmgr";

qrsc.ClientCredentials.UserName.Password = "medmgr";

qrsc.Open();

try

            {

              QueryService.wsFile[] files2 = qrsc.getFiles("CWLUQZLTHXTZWI");

               MessageBox.Show("OK");

            }

           catch(Exception ex){

                MessageBox.Show("KO " + ex.Message);

            }
