我正在创建VPN WPF软件，我有适用于所有内容的API，假设服务器列表它的链接是
https://webservice.abcd.com/serverlist
现在我有服务器列表的模型类
using System;
using System.Collections.Generic;
using System.Text;
namespace VirtualPN.Model
{
class ServerModel
{
public string error { get; set; }
public string message { get; set; }
public Server[] servers { get; set; }

现在我有多个国家/地区的服务器，并希望在窗口中将其显示为ListView，其中每个服务器都可以选择连接VPN服务。我怎样才能做到这一点。国家名称，城市DNS很重要。

如果您使用的是 MVVM：
一般的方法是将服务器的集合保存在ObservableCollection中，并将其绑定到ListView的ItemsSource属性。
如果您未使用 MVVM：
您可以从Window的代码中设置/更新ListView的ItemsSource属性。
也。。。
您可以通过将ListView的ItemTemplate属性设置为自定义DataTemplate并在那里执行任何操作来定义项目的外观和显示的数据。
这是和 MVVM 示例
窗口 XAML 代码：
<Window x:Class="ExampleApp.ServerView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
Title="ServerView" Height="450" Width="800">
<Grid>
<ListView ItemsSource="{Binding Servers}" SelectedItem="{Binding SelectedServer}" SelectionMode="Single">
<ListView.ItemTemplate>
<DataTemplate>
<Border Padding="5">
<StackPanel>
<TextBlock Text="{Binding CountryName, StringFormat='Country: {0}'}" />
<TextBlock Text="{Binding CityDns, StringFormat='DNS: {0}'}" />
</StackPanel>
</Border>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<Button Content="Refresh" Click="BtnRefresh_Click" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="10" Padding="10"/>
</Grid>
</Window>
代码背后的窗口代码：
using System.Windows;
namespace ExampleApp
{
public partial class ServerView : Window
{
private readonly ServerViewModel _model;
public ServerView()
{
InitializeComponent();
_model = new ServerViewModel();
DataContext = _model;
}
private void BtnRefresh_Click(object sender, RoutedEventArgs e)
{
_model.ReloadServers();
}
}
}
视图模型和服务器类代码：
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.ComponentModel;
using System.Runtime.CompilerServices;
namespace ExampleApp
{
public class ServerViewModel : INotifyPropertyChanged
{
public ObservableCollection<Server> Servers { get; set; } = new ObservableCollection<Server>();
private Server _selectedServer;
public Server SelectedServer
{
get => _selectedServer;
set
{
if(_selectedServer != value)
{
_selectedServer = value;
OnPropertyChanged();
SelectedServerChanged();
}
}
}
public void SelectedServerChanged()
{
//do whatever you need to do when the selected server changes here...
System.Console.WriteLine($"The selected server has changed: {SelectedServer.CountryName}");
}
public void ReloadServers()
{
var servers = DownloadServers();
Servers.Clear();
foreach (var server in servers)
{
Servers.Add(server);
}
}
private List<Server> DownloadServers()
{
//pretend we're downloading the list of servers here...
return new List<Server>
{
new Server { CityDns = "Some DNS", CountryName = "England" },
new Server { CityDns = "Some other DNS", CountryName = "China" },
new Server { CityDns = "Another DNS", CountryName = "United States" }
};
}
public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged([CallerMemberName] string propertyName = "")
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
public class Server
{
public string CountryName { get; set; }
public string CityDns { get; set; }
}
}
请注意，我没有使用ICommand来单击刷新按钮，我通常会这样做。
