c# 代码 编译出现常量中有换行符错误

c#的代码我是从VS中直接粘贴到Quicker中的并进行了少许修改，但是一直提示出现常量中有换行符错误。从网上查了一下很多都说是编码的问题，但是Quicker中好像没有设置编码的地方。请问有没有解决的方案？

以下是尝试执行的代码：

//.cs  文件类型，便于外部编辑时使用
// 引用必要的命名空间
using System.Windows.Forms;
using Newtonsoft.Json.Linq;
using OfficeOpenXml;
using System.Net;
using System.Text;

public class SingleDaHangHai
{
    public long uid { get; set; }
    public long ruid { get; set; }
    public string username { get; set; }
    public int guard_level { get; set; }
}

public static List<SingleDaHangHai> getDaHangHai(string roomID, string uid)
{
    List<SingleDaHangHai> daHangHais = new List<SingleDaHangHai>();
    int pageIdx = 1;
    string url = "https://api.live.bilibili.com/xlive/app-room/v2/guardTab/topList?roomid=" + roomID + "&page=" + pageIdx + "&ruid" + uid";
    JObject o = JObject.Parse(GetRequest(url));
    int totalDaHangHai = (int)o["data"]["info"]["num"];
    JArray top3 = (JArray)o["data"]["top3"];
    foreach (var dhh in top3)
    {
        daHangHais.Add(
            new SingleDaHangHai
            {
                uid = (long)dhh["uid"],
                ruid = (long)dhh["ruid"],
                username = (string)dhh["username"],
                guard_level = (int)dhh["guard_level"]
            });
    }

    //总页数
    int totalPages = (int)o["data"]["info"]["page"];
    for (int i = 1; i <= totalPages; i++)
    {
        if (i != 1)
        {
            url = "https://api.live.bilibili.com/xlive/app-room/v2/guardTab/topList?roomid="+ roomID + "&page=" + i + "&ruid=" + uid";
            o = JObject.Parse(GetRequest(url));
        }
        //列表

        {

                    guard_level = (int)dhh["guard_level"]
                });
        }
    }
    if (daHangHais.Count != totalDaHangHai)
    {
        return null;
    }
    return daHangHais;
