Question

我有两个包含相同数据的类，但由于Type混淆，我无法在两者之间传递值。

这是两个类，

public class Employee
{
    public int Key { get; set; }
    public string FirstName { get; set; }
    public string SecondName { get; set; }
    public string FullName => FirstName + " " + SecondName;

    public Employee(int key, string first = null, string second = null)
    {
        Key = key;
        FirstName = first;
        SecondName = second;
    }
}

public class EmployeeList
{
    public int Key { get; set; }
    public string FirstName { get; set; }
    public string SecondName { get; set; }
    public string FullName => FirstName + " " + SecondName;

    public EmployeeList(int key, string first = null, string second = null)
    {
        Key = key;
        FirstName = first;
        SecondName = second;
    }
}

然后我使用属性通过LINQ查询存储数据

public ObservableCollection<Employee> Staff { get; set; } =
   new ObservableCollection<Employee>();

public ObservableCollection<EmployeeList> StaffAll { get; set; } =
   new ObservableCollection<EmployeeList>();

然后我将值传递给每个的属性，

private Employee _selectedEmployee;

public Employee SelectedEmployee
{
    get { return _selectedEmployee; }
    set
    {
        _selectedEmployee = value;
        NotifyPropertyChanged();
    }
}

private EmployeeList _selectedEmployeeAll;

public EmployeeList SelectedEmployeeAll
{
    get { return _selectedEmployeeAll; }
    set
    {
        _selectedEmployeeAll = value;
        NotifyPropertyChanged();
    }
}

例如，

SelectedEmployee = Staff.First();
SelectedEmployeeAll = StaffAll.First();

我想要做的是将值从一个类传递到另一个类，就像这样，

SelectedEmployee = SelectedEmployeeAll;

但粗略的，由于type冲突，我无法将数据从一个传递到另一个。如何将数据从一种类型传递到另一种类型？

Answer 1

您应该从Employee创建EmployeeList：

SelectedEmployee = new Employee(SelectedEmployeeAll.Key, SelectedEmployeeAll.FirstName, SelectedEmployeeAll.SecondName);

但是你应该尝试只使用一种类型，因为拥有两种相同的类型并不是一个好的设计。

如果您想在多个应用中使用它，请考虑创建共享Class Library。

我无法理解您使用不同名称的一个类。你可以这样做：

public class EmployeeList:Employee
{
    public int Key { get; set; }
    public string FirstName { get; set; }
    public string SecondName { get; set; }
    public string FullName => FirstName + " " + SecondName;

    public EmployeeList(int key, string first = null, string second = null)
    {
        Key = key;
        FirstName = first;
        SecondName = second;
    }
}

但我认为，正确的方法是只使用一个班级。

如何转换类型，或在类型之间传递值？
