ExtensionDataObject显示在服务引用中

Question

我正在编写WCF服务， ExtensionDataObject 显示在服务参考的 Reference.cs 文件中，即使我没有它在我的数据类中定义。

我知道ExtensionDataObject的用途，但不想使用它。

我不知道为什么会出现 ... 有人可以告诉我如何不将它包含在我的服务参考中吗？此外，还有一个OptionalFieldAttribute，在我的服务引用中声明，它再次不是我的数据类的一部分。我怎么能删除它？

以下是我客户端上生成的服务引用声明：

[System.Diagnostics.DebuggerStepThroughAttribute()]

            }
            set {
                if ((object.ReferenceEquals(this.PasswordField, value) != true)) {
                    this.PasswordField = value;
                    this.RaisePropertyChanged("Password");
                }
            }
        }

                if ((object.ReferenceEquals(this.PermissionsField, value) != true)) {
                    this.PermissionsField = value;
                    this.RaisePropertyChanged("Permissions");
                }
            }
        }

        [System.Runtime.Serialization.DataMemberAttribute()]

                    this.UserIDField = value;
                    this.RaisePropertyChanged("UserID");
                }
            }
        }

        [System.Runtime.Serialization.DataMemberAttribute()]
        public Ryder.ShopProcessService.Outbound.ShopProcessService.UserTypeEnum UserType {

            }
            set {
                if ((this.UserTypeField.Equals(value) != true)) {
                    this.UserTypeField = value;
                    this.RaisePropertyChanged("UserType");
                }
            }
        }

        public event System.ComponentModel.PropertyChangedEventHandler PropertyChanged;

        protected void RaisePropertyChanged(string propertyName) {
            System.ComponentModel.PropertyChangedEventHandler propertyChanged = this.PropertyChanged;
            if ((propertyChanged != null)) {
                propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
            }
        }
    }

这是我的服务项目中相应的类声明：请注意，我刚刚将名称空间更改为“abc”以保护隐私......
