Question

Okay, so I am having problems calling the method GetClassAverage() from the interfacce (the windows form displaying the data). I get the following error too "The modifier public is not valid for this item"... this is the code on my IService.cs file

[ServiceContract]
public interface IClassRollService
{
    [OperationContract]
    List<Student> GetStudentList(int semester);
    [OperationContract]    
    double GetClassAverage(int anything);
}

在我的服务档案中,我

public double GetClassAverage()
{
    double sum = 0.0;
    double total;
    foreach (Student S in Students)
    {
        sum += S.Average;
    }
    return total = sum / Students.Count();
}

在我的窗口表上,我通过打电话给客户填写了电网。 GetStudentList()但并不为GetClassAverage()工作。

我做了什么错误或我失踪了什么?

[EDIT]已向公众开放,但我仍然能够从Windows表格中提一下这种方法。是否有其他办法,我可以把这种方法的回馈价值带入窗口表格。这与我所知道的网络服务有关。

Answer 1

在接口中,所有方法都按定义公开。因此,它告诉你“公众”是不有效的。仅从您的界面方法定义中删除“公开”关键词,所有东西都将被罚款。

Your edited IService.cs looks good. You need 页: 1change your implementation signature in Service.cs 页: 1match your interface:

public double GetClassAverage()

页: 1

public double GetClassAverage(int anything)
