我正在创建一个 WCF 服务,该服务将用于将数据插入数据库。
WCF 服务在使用本地限定在服务本身的接口和类内的函数时正常运行,但是,当我使用外部 DLL 中的类时,它无法启动。
我确保 DLL 中的类具有所有必需的属性,但仍然无法运行该服务。
有任何想法吗?
编辑:这是错误的功能
public Dal_Users createProfile(DateTime dateOfBirth, string email, string firstname, bool genderIsMale, string lastname, string mphoneno, string nickname, string password, string pictureURL)
{
try
{
//generate new user object
/////////////////////////start user metadata/////////////////////////////////////////
Dal_Users newUser = new Dal_Users();
newUser.DateOfBirth = dateOfBirth;
newUser.Email = email;
newUser.FirstName = firstname;
newUser.GenderIsMale = genderIsMale;
newUser.LastName = lastname;
newUser.MPhoneNo = mphoneno;
newUser.NickName = nickname;
newUser.Password = password;
newUser.ProfilePicture = pictureURL;
//////////////////////////////end user metadata///////////////////////////////////////
//insert user in database, call updateUsers without an ID
newUser.UpdateUsers();
return newUser;
}
catch (Exception ex)
{
return new Dal_Users();
}
}
DAL_Users 类来自 DLL,并被标记为DataContract
/// <summary>
/// this is the data access class for the table Users
/// </summary>
[DataContract]
public class Dal_Users

My app.config looks like this
