VB.Net WebAPI 2不过滤记录

Question

我刚刚开始学习Web API2控制器，并且遇到了一些困难。在C＃中，它可以很好地调用所有记录和过滤，但是使用VB.Net可以很好地获取所有记录但是在过滤特定记录时它不起作用。以下是代码：

C＃代码正常工作：

public class EmployeesController : ApiController
{
    public IEnumerable<Employee> Get()
    {
        using (EmployeeDBEntities entities = new EmployeeDBEntities())
        {
            return entities.Employees.ToList();
        }
    }

    public Employee Get(int id)
    {
        using (EmployeeDBEntities entities = new EmployeeDBEntities())
        {
            return entities.Employees.FirstOrDefault(e => e.ID == id);
        }
    }
}

VB.Net代码仅在获取所有记录时才能正常工作，但在过滤特定记录时则无效：

Public Class EmployeesController
    Inherits ApiController

    Public Function GetValues() As IEnumerable(Of Employee)
        Using entities As EmployeeDBEntities = New EmployeeDBEntities()
            Return entities.Employees.ToList
        End Using
    End Function

    Public Function GetValues(vID As Integer) As Employee
        Using entities As EmployeeDBEntities = New EmployeeDBEntities()
            Return entities.Employees.FirstOrDefault(Function(e) e.ID = vID)
        End Using
    End Function

End Class

非常感谢您的帮助！
