服务器代码，没写配置都是通过代码实现

 string Url = (string)config.GetValue("ServerAddress", typeof(string));
            WSHttpBinding binding = new WSHttpBinding();
            binding.Security.Mode = SecurityMode.Message;
            binding.Security.Message.ClientCredentialType =MessageCredentialType.Certificate;
            ServiceMetadataBehavior met = new ServiceMetadataBehavior();
            met = new ServiceMetadataBehavior() { HttpGetEnabled = true };
            
            Uri httpUri = new Uri(Url);
            
        
            ServiceHost myServiceHost = new ServiceHost(typeof(DataService), httpUri);
            myServiceHost.AddServiceEndpoint(typeof(IDataService), binding, "");
            myServiceHost.Description.Behaviors.Add(met);
            
            myServiceHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My, X509FindType.FindBySubjectName, "MyCert");
            myServiceHost.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = System.ServiceModel.Security.UserNamePasswordValidationMode.Custom;
            myServiceHost.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new CustomValidator();
           //host承载服务
            try
            {
                myServiceHost.Open();
                if (myServiceHost.State == CommunicationState.Opened)//判断服务状态
                    return true;
                else
                    return false;
            }
            catch (Exception e)
            {
                return false;
            }

客户端

 DataServiceClient data = new DataServiceClient();
            data.ClientCredentials.UserName.UserName = "xiao";
            data.ClientCredentials.UserName.Password = "123456";
         
            Label1.Text = data.PrintMessage("123");

在线等丫，求助，顶上去

[写个昵称都这么麻烦]

设置了身份验证、X509证书验证（你证书授权了没） 授权了就新建个类继承'System.IdentityModel.Selectors.UserNamePasswordValidator' 然后我们重写里面的'Validate'方法来实现用户名密码认证

public class UserNamePasswordValidator : System.IdentityModel.Selectors.UserNamePasswordValidator 
{ 
    public override void Validate(string userName, string password) 
    { 
        if (userName != "xiao" || password != "123456") 
        { 
            throw new System.IdentityModel.Tokens.SecurityTokenException("Unknown Username or Password"); 
        } 
    } 
}
