我正在創建2個wcf服務 - ADService & DBService。我使用稱爲EmployeeDTO和CustomerDTO的DTO來在端點之間交換數據。 我不能在我的解決方案中添加任何服務，服務引用到其他項目的，當我運行WCF主機和嘗試訪問ADService.svc或DBService.svc我得到如下：類型'MyDTO'無法序列化 - Wcf服務
Type 'DTOs.CustomerDTO' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute.
和
Type 'DTOs.EmployeeDTO' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute.
我的文件看起來如下：
類CustomerDTO
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace DTOs
{
public class CustomerDTO
{
public int customerID;
public string name;
public string surname;
public string street;
public string post_code;
public string city;
public string country;
public string personal_code;
public string phone_number;
public string group_type;
public string employee;
public CustomerDTO(int _customerID, string _name, string _surname, string _street, string _post_code, string _city, string _country, string _personal_code, string _phone_number, string _group_type, string _employee)
{
this.customerID = _customerID;
this.name = _name;
this.surname = _surname;
this.street = _street;
this.post_code = _post_code;
this.city = _city;
this.country = _country;
this.personal_code = _personal_code;
this.phone_number = _phone_number;
this.group_type = _group_type;
this.employee = _employee;
}
}
}
類EmployeeDTO：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace DTOs
{
public class EmployeeDTO
{
public string givenName;
public string sn;
public string telephoneNumber;
public string sAMAccountName;
public string title;
public string Department;
public string distinguishedName;
public string OU;
public bool enable;
public EmployeeDTO(string _givenName, string _sn, string _telephoneNumber, string _sAMAccountName, string _title, string _Department, string _distinguishedName, string _OU, bool _enable)
{
this.Department = _Department;
this.distinguishedName = _distinguishedName;
this.givenName = _givenName;
this.sAMAccountName = _sAMAccountName;
this.sn = _sn;
this.telephoneNumber = _telephoneNumber;
this.title = _title;
this.OU = _OU;
this.enable = _enable;
}
}
}

IDBService.cs模擬方式定義。
我似乎無法找到這個錯誤的原因，特別是我的一個朋友有一個類似的實現，它的工作，而我的沒有。 任何幫助將深表謝意。
你想序列化與'DataMemberAttribute'屬性你考慮使用'DataContractAttribute'屬性標記它，標誌着其所有成員？ – Matthew
