如何从xamarin表单的web api分页列表视图分页同步中获取json数据？

using System;
using System.Collections.Generic;
using System.Net.Http;
using System.Threading.Tasks;

public class MyPage : ContentPage
{
    private ListView listView;
    private List<MyDataModel> dataList;

    public MyPage()
    {
        listView = new ListView();
        Content = listView;
    }

    protected override async void OnAppearing()
    {
        base.OnAppearing();

        // 发送HTTP请求获取JSON数据
        var httpClient = new HttpClient();
        var response = await httpClient.GetAsync("http://your-web-api-url");
        if (response.IsSuccessStatusCode)
        {
            var json = await response.Content.ReadAsStringAsync();

            // 解析JSON数据
            dataList = Newtonsoft.Json.JsonConvert.DeserializeObject<List<MyDataModel>>(json);

            // 将数据绑定到列表视图
            listView.ItemsSource = dataList;
        }
    }
}

public class MyDataModel
{
    public string Name { get; set; }
    public string Description { get; set; }
    // 其他属性...
}
