Question

我是C＃的新手，我通过WPF练习我的知识。我正在尝试创建一个＆＃34; EmployeeDatabase＆＃34;

public EmployeeDB()
{
    _employeeList.Add(new EmployeeApp1.Employee() { Name = "Hecbert Doval", Email = "haloha@gmail.com", Salary = 14000 });
    _employeeList.Add(new EmployeeApp1.Employee() { Name = "Harry Pottah", Email = "haloha@gmail.com", Salary = 653000 });
    _employeeList.Add(new EmployeeApp1.Employee() { Name = "Amino Vikola", Email = "haloha@gmail.com", Salary = 230 });
    _employeeList.Add(new EmployeeApp1.Employee() { Name = "Mila Spino", Email = "haloha@gmail.com", Salary = 30000 });
    _employeeList.Add(new EmployeeApp1.Employee() { Name = "Tila Tequila", Email = "haloha@gmail.com", Salary = 90700 });
    _employeeList.Add(new EmployeeApp1.Employee() { Name = "TheRock Johnson", Email = "haloha@gmail.com", Salary = 14500 });
}
private List<Employee> _employeeList;

使用＆＃34;员工列表＆＃34;对象和每个Employee对象都有＆＃34;姓名，薪水，电子邮件＆＃34;作为属性。

public class Employee
{
    public string Name { get; set; }
    public string Email { get; set; }
    public int Salary { get; set; }
}

接下来，我创建了3个列表视图，将它们并排排列，每个列表视图都应该收到＆＃34; Name＆＃34; ＆＃34;电子邮件＆＃34;和＆＃34;薪水＆＃34;单独。

<ListView Name="lvName" Margin="20" Grid.Column="0" />
<ListView Name="lvEmail" Margin="20" Grid.Column="1" />
<ListView Name="lvSalary" Margin="20" Grid.Column="2" />

我的问题是如何将每个ListView绑定到名称/电子邮件/工资？如果有可能..如果没有任何替代方案可以达到相同的结果？提前谢谢！

出于好奇，为什么你想要三个相邻的列表视图，每个只显示一个属性？

顺便问一下，您是否正在实施INotifyPropertyChanged？你应该。

无论如何，这很容易。首先，公开_employeeList：

private ObservableCollection<Employee> _employeeList
    = new ObservableCollection<Employee>();

public ObservableCollection<Employee> EmployeeList { get { return _employeeList; } }

然后，绑定：

<ListView 
    ItemsSource="{Binding EmployeeList}" 
    DisplayMemberPath="Name"
    Name="lvName"
    Margin="20" Grid.Column="0" 
    />

<ListView 
    ItemsSource="{Binding EmployeeList}" 
    DisplayMemberPath="Email"
    Name="lvEmail"
    Margin="20" Grid.Column="1" 
    />

<ListView 
    ItemsSource="{Binding EmployeeList}" 
    DisplayMemberPath="Salary"
    Name="lvSalary"
    Margin="20" Grid.Column="2" 
    />

如果您更愿意在代码隐藏中做所有事情，那么根据我向您展示的内容，您可以轻松找到自己。
