WCF未实现接口成员

Question

I am working on a wcf service that connects to database. I had debugged and tested my operation playerregistration and clubregistration. I then tried to test the get functions but i received the error:

Error 1 'WebApplication1.ADOService' does not implement interface member 'WebApplication1.IADOService.newMembership(WebApplication1.playerDetails, WebApplication1.playerDetails, WebApplication1.clubDetails, WebApplication1.memberDetails)' C:\\Users\\Daniel\\Documents\\Visual Studio 2013\\Projects\\Prac4\\WebApplication1\\ADOService.svc.cs 14 18 WebApplication1

following the error I attempted to remove the get functions however the error remains. Below is the service code

public class ADOService : IADOService
{
    public string playerRegistration(playerDetails playerInfo)
    {

        string Message;
        using (SqlConnection conn = new SqlConnection("Data Source=(LocalDB)\\v11.0;AttachDbFilename=c:\\Users\\Daniel\\documents\\visual studio 2013\\Projects\\Prac4\\WebApplication1\\App_Data\\ADODatabase.mdf;Integrated Security=True"))
        {
            conn.Open();

            using (var cmd = new SqlCommand("INSERT into Player(pid, pfname, plname, pphone, paddress, pdob) VALUES (@pid, @pfname, @plname, @pphone, @paddress, @pdob)", conn))
            {
                cmd.Parameters.AddWithValue("@pid", playerInfo.Pid);
                cmd.Parameters.AddWithValue("@pfname", playerInfo.Pfname);

                cmd.Parameters.AddWithValue("@pdob", playerInfo.Pdob);

                int result = cmd.ExecuteNonQuery();
                if (result == 1)
                {
                    Message = playerInfo.Pid + " Details inserted successfully";

                else

And Iservice code

[ServiceContract]
public interface IADOService
{
    [OperationContract]
    string playerRegistration(playerDetails playerInfo);

    [OperationContract]
    string clubRegistration(clubDetails clubInfo);

    List<playerDetails> getplayerInfo(string pfname, string plname);

    [OperationContract]
    List<clubDetails> getclubInfo(string cname);

    [OperationContract]
    string newMembership(playerDetails pfname, playerDetails plname, clubDetails cname, memberDetails memberstart);
}
[DataContract]
public class playerDetails
{
    int pid;
    string pfname;
    string plname;
    int pphone;
    string paddress;
    DateTime pdob;


    [DataMember]
    public int Pid
    {
        get { return pid; }
        set { pid = value; }
    }
    [DataMember]
    public string Pfname
    {
        get { return pfname; }
        set { pfname = value; }
    }
    [DataMember]
    public string Plname
    {
        get { return plname; }
        set { plname = value; }
    }
    [DataMember]
    public int Pphone
    {
        get { return pphone; }
        set { pphone = value; }
    }
    [DataMember]
    public string Paddress
    {
        get { return paddress; }
        set { paddress = value; }
    }
    [DataMember]
    public DateTime Pdob
    {
        get { return pdob; }
        set { pdob = value; }
    }

}

[DataContract]
public class clubDetails
{
    int cid;
    string cname;
    DateTime cfounded;
    int cworldranking;


    [DataMember]
    public int Cid
    {
        get { return cid; }
        set { cid = value; }
    }
    [DataMember]
    public string Cname
    {
        get { return cname; }
        set { cname = value; }
    }
    [DataMember]
    public DateTime Cfounded
    {
        get { return cfounded; }
        set { cfounded = value; }
    }
    [DataMember]
    public int Cworldranking
    {
        get { return cworldranking; }
        set { cworldranking = value; }
    }
}
[DataContract]
public class memberDetails
{
    int mid;
    DateTime memberstart;
    DateTime memberend;
    int gamesplayed;

[DataMember]
    public int Mid
    {
        get { return mid; }
        set { mid = value; }
    }
    [DataMember]
    public DateTime Memberstart
    {
        get { return memberstart; }
        set { memberstart = value; }
    }
    [DataMember]
    public DateTime Memberend
    {
        get { return memberend; }
        set { memberend = value; }
    }
     [DataMember]
    public int Gamesplayed
    {
        get { return gamesplayed; }
        set { gamesplayed = value; }
    }
}

}

I am assuming that the get functions are the cause of the problem but not sure how to address the error.

Answer 1

You've defined the following methods in your interface:

string playerRegistration(playerDetails playerInfo);
string clubRegistration(clubDetails clubInfo);
List<playerDetails> getplayerInfo(string pfname, string plname);
List<clubDetails> getclubInfo(string cname);
string newMembership(playerDetails pfname, playerDetails plname, clubDetails cname, memberDetails memberstart);

But only implemented four of them:

playerRegistration
clubRegistration
getplayerInfo
getclubInfo

You haven't actually implemented newMembership in the ADOService class.
