No se por que tienes tanto ahi, cno esto deberia valerte:
Código:
public static void SetNetworkCredentials(System.Web.Services.Protocol s.SoapHttpClientProtocol SC)
{
string wsUser = System.Configuration.ConfigurationManager.AppSetti ngs["AccessPointUser"].ToString();
string wsPassword = System.Configuration.ConfigurationManager.AppSetti ngs["AccessPointPassword"].ToString();
string wsDomain = System.Configuration.ConfigurationManager.AppSetti ngs["AccessPointDomain"].ToString();
System.Net.NetworkCredential networkCredential = new System.Net.NetworkCredential(wsUser, wsPassword, wsDomain);
tuClaseServicioWeb objServicioWeb = new tuClaseServicioWeb();
objServicioWeb.Credentials = networkCredential;
}
Y deberia funcionarte.
Saludos.
