Binance api 仅获取 USDT 对 - 通过仅从最后 4 个字母为 USDT 的交易品种获取数据来实现

Question

我这里有一个函数可以从 binance api 获取数据，但问题是，它获取所有交易对。我只想在我的选择器中显示以 USDT 结尾的那些。我该怎么做？

        public class Crypto
        {
            public string symbol { get; set; }
            public string price { get; set; }
        }


        private async void GetSymbol()
        {
            HttpClient client = new HttpClient();
            var response = await client.GetStringAsync("https://api.binance.com/api/v3/ticker/price");
            var cryptoconverted = JsonConvert.DeserializeObject<List<Crypto>>(response);
            var sorted = cryptoconverted.OrderBy(x => x.symbol).ToList();
            pairPicker.ItemsSource = sorted;

        }

Answer 1

您可以使用EndsWith() as a condition inside of Linq Where()方法：

 var sorted = cryptoconverted.OrderBy(x => x.symbol).Where(x => x.symbol.EndsWith("USDT")).ToList();
