是否有人使用request.ContentType中的application/edn发布来自C# .Net的查询请求。引号需要转义序列

using System;
using System.Net.Http;
using System.Text;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        using (HttpClient client = new HttpClient())
        {
            // 构造查询请求的数据
            var queryData = new { key1 = "value1", key2 = "value2" };
            var json = Newtonsoft.Json.JsonConvert.SerializeObject(queryData);
            var content = new StringContent(json, Encoding.UTF8, "application/json");

            // 发送查询请求
            var response = await client.PostAsync("https://example.com/query", content);

            // 处理响应
            var result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);
        }
    }
}
