単純なデータベース テーブルを更新するための Web サービスを作成しようとしています。Employee 型のオブジェクトをパラメーターとして受け取る update メソッドがあります。Employee クラスが属する名前空間の参照を含めました。理解できない理由で、次のエラーが表示されます: Inconsistent accessibility: parameter type 'EmployeeDBApplication.Employee' is lessaccessible than method 'EmployeeStoreWS.EmployeeStoreService.update(EmployeeDBApplication.Employee)'
class Employee
{
private int id;
public int Id
{
get { return id; }
set { id = value; }
}
private double salary;
public double Salary
{
get { return salary; }
set { salary = value; }
}
private string address;
public string Address
{
get { return address; }
set { address = value; }
}
private string firstname;
public string Firstname
{
get { return firstname; }
set { firstname = value; }
}
private string lastname;
public string Lastname
{
get { return lastname; }
set { lastname = value; }
}
public override string ToString() {
string x;
x = "Employee ID:" + this.id + "\tName:" + this.firstname + "\t" + this.lastname + "\n\tSalary:" + this.salary + "\t Address:" + this.address;
return x;
