我正在创建一个WCF服务,用于将数据插入数据库。
当使用本地作用于接口和服务本身类的函数时,WCF服务正常运行,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。
有什么想法吗?
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,标记为DataContract
/// <summary>
/// this is the data access class for the table Users
/// </summary>
[DataContract]
public class Dal_Users
EDIT2:
My app.config looks like this
<system.serviceModel>
<services>
<service name="ProfileService.ProfileMgr">
<endpoint address="" binding="wsHttpBinding" contract="ProfileService.IProfileMgr">

我收到的错误是

Receivera:InternalServiceFault
由于内部错误,服务器无法处理请求。有关错误的更多信息,请在服务器上启用IncludeExceptionDetailInFaults(来自ServiceBehaviorAttribute或来自&lt; serviceDebug&gt;配置行为),以便将异常信息发送回客户端,或者根据Microsoft .NET打开跟踪Framework 3.0 SDK文档并检查服务器跟踪日志.HTTP GET错误URI:http://localhost:8732/Design_Time_Addresses/ProfileService/Service1/mex下载'http:// localhost:8732 / Design_Time_Addresses / ProfileService / Service1 / mex'时出错。请求失败,HTTP状态为400:错误请求。

如果您尝试将服务和服务合同移至外部程序集,则需要修改.svc文件以指向该程序集。
<%@ ServiceHost Language="C#" Debug="true" Service="FULLASSEMBLYNAMEHERE" %>

尝试在true
中将includeExceptionDetailInFaults
设置为web.config
,以便在请求MEX端点时看到生成的错误消息。
请参阅this SO post,它与您收到的错误相似( HTTP状态400:错误请求)。
