＆＃39; UserWcfService.userService＆＃39;没有实现接口成员＆＃39; UserWcfService.IuserService.Getuserdetails（）＆＃39 ;. ＆＃39; UserWcfService.userService.Getuserdetails（）＆＃39;无法实现接口成员，因为它不是上市。 C：\ Users \ ravi \ Documents \ Visual Studio 2013 \ Projects \ wcfservices \ UserWcfService \ UserWcfService \ userService.svc.cs 16 18 UserWcfService

userservice.svc.cs代码：

namespace UserWcfService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "userService" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select userService.svc or userService.svc.cs at the Solution Explorer and start debugging.
    public class userService : IuserService
    {
        public string str = ConfigurationManager.ConnectionStrings["connstring"].ToString();
        List<usertype> Getuserdetails()
    {
        List<usertype> userdetails=new List<usertype>();

        SqlConnection conn = new SqlConnection(str);

        {
            conn.Open();
            SqlCommand cmd = new SqlCommand("spgetdata", conn);
            cmd.CommandType = CommandType.StoredProcedure;

            SqlDataAdapter da = new SqlDataAdapter(cmd);
            DataTable dt = new DataTable();
            da.Fill(dt);

            if (dt.Rows.Count > 0)
            {
                for(int i=0; i<dt.Rows.Count; i++)
                {
                    usertype objinfo = new usertype();
                    objinfo.name = Convert.ToString(dt.Rows[i]["name"]);
                    objinfo.gender = Convert.ToString(dt.Rows[i]["gender"]);
                    objinfo.dateofbirth = Convert.ToDateTime(dt.Rows[i]["dateofbirth"]);
                    objinfo.address = Convert.ToString(dt.Rows[i]["address"]);
                    objinfo.contactno = Convert.ToInt32(dt.Rows[i]["contactno"]);
                    objinfo.mailid = Convert.ToString(dt.Rows[i]["mailid"]);
                    userdetails.Add(objinfo);
                }
            }
            conn.Close();
        }
        return userdetails;
    }

    public string newuser(usertype user)
    {
            string strmessage; 
            SqlConnection conn = new SqlConnection(str);
            {
                conn.Open();
                SqlCommand cmd = new SqlCommand("spinsert", conn);
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.AddWithValue("@C_Users_Name", user.name);
                cmd.Parameters.AddWithValue("@C_Users_Gender", user.gender);
                cmd.Parameters.AddWithValue("@lC_Users_DOB", user.dateofbirth);
                cmd.Parameters.AddWithValue("@C_Users_Address", user.address);
                cmd.Parameters.AddWithValue("@C_Users_ContactNo", user.contactno);
                cmd.Parameters.AddWithValue("@C_Users_MailID", user.mailid);
                //cmd.Parameters.AddWithValue("@C_Users_RegisteredDate", userinfo.date);
                int result = cmd.ExecuteNonQuery();

                if(result==1)
                {
                    strmessage = user.name + "details inserted succesfully";
                }
                else
                {
                    strmessage = user.name + "Details not inserted";
                }
                conn.Close();
            }

            return strmessage;
       }
    }
}

和IUserService代码：

namespace UserWcfService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IuserService" in both code and config file together.
    [ServiceContract]
    public interface IuserService
    {
        [OperationContract]
        List<usertype> Getuserdetails();

        [OperationContract]
        string newuser(usertype user);
    }

    [DataContract]
    public class usertype
    {
        [DataMember]
        public string name { get; set; }
        [DataMember]
        public string gender { get; set; }
        [DataMember]
        public DateTime dateofbirth { get; set; }
        [DataMember]
        public string address { get; set; }
        [DataMember]
        public int contactno { get; set; }
        [DataMember]
        public string mailid { get; set; }
        [DataMember]
        public DateTime date { get; set; }
    }
}

Answer 1

默认情况下，所有接口方法都是公共的，因此您的类接口也需要公开。

Answer 2

在此处查看您的错误的一个好方法是右键单击

中的IuserService

$("#date-birth").on("keyup", function() {
    var dt = moment(this.value, 'DD/MM/YYYY', true);
    if( dt.isValid() ){
        $('#datetimepicker1').data("DateTimePicker").date(dt);
    }
});

去实现界面 - ＆gt;明确实现接口

这将创建实现您的接口的存根方法。您可以将代码放入其中，也可以调整适当的方法

这是一个使用上面描述的方法构建我的例子

在创建WCF服务时，我收到错误：没有实现接口成员
