如何在 WCF 中设置安全令牌？

<bindings>
  <wsHttpBinding>
    <binding name="SecureBinding">
      <security mode="Message">
        <message clientCredentialType="UserName" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

public class CustomUserNameValidator : UserNamePasswordValidator
{
    public override void Validate(string userName, string password)
    {
        if (userName != "admin" || password != "password")
        {
            throw new FaultException("Invalid username or password");
        }
    }
}
