如何使用C#从MS Project Rest api中读取纯文本？

using System;
using System.Net.Http;
using Newtonsoft.Json;

class Program
{
    static async System.Threading.Tasks.Task Main(string[] args)
    {
        // 创建HttpClient对象
        using (HttpClient client = new HttpClient())
        {
            // 设置API请求URL
            string apiUrl = "https://api.project.com/tasks";

            // 发送GET请求并获取响应
            HttpResponseMessage response = await client.GetAsync(apiUrl);

            // 检查响应是否成功
            if (response.IsSuccessStatusCode)
            {
                // 读取响应内容
                string responseContent = await response.Content.ReadAsStringAsync();

                // 解析响应内容为纯文本
                string plainText = JsonConvert.DeserializeObject<string>(responseContent);

                // 处理纯文本数据
                Console.WriteLine("纯文本数据：");
                Console.WriteLine(plainText);
            }
            else
            {
                Console.WriteLine("请求失败，状态码：" + response.StatusCode);
            }
        }
    }
}
