从 API (C#) 解析 JSON 数据

Question

我目前正在从 web api 以 application/json 数据的形式获取信息。我遇到的问题是，有时我在使用 JObject.Parse(response) 时会出错，而在使用 JArray.Parse(response) 时却没有，有时反之亦然。我一直在四处寻找，但无法弄清楚为什么返回的某些数据有 [] 而有些则没有。话虽如此，有没有办法一致地解析数据，无论它是否有 [] ？我目前唯一能想到的是检查响应字符串是否以'['开头，如果是则使用JArray.Parse，如果不是则使用JObject.Parse，但这看起来有点难看解决方案。总的来说，我对 API 还是很陌生，所以任何建议都将不胜感激。

代码片段：

using (WebClient webClient = new WebClient())
{
    webClient.Headers.Add("Authorization", "Basic ***");
    webClient.Headers.Add("clientId", clientId);
    webClient.Headers.Add("Content-Type", "application/json");
    string agreementResponse = webClient.DownloadString(urlAgreementBase + urlAgreementParams);
    if (response == null)
    {
        throw new InvalidPluginExecutionException("Failed to retrieve company. Response was empty.");
    }
    var agreementObject = JArray.Parse(response);
}

当我从服务器后端接收数据时，我使用JSON.parse(response) 我假设您正在使用 JaveScript 编写代码。这是我为我的 webapp 编写的示例；

 $.get("/tictactoe/" + ID, {"thePosition": curr_line}, function(response){
        let x = JSON.parse(response); //here x is now a JSON object
          for(let i = 0; i <= 2; i++){
              for(let j = 0; j <= 4; j++){
                  console.log(x.gb[i][j]); //x holds a 2D-array called gb, 
                  //you can access it with x["gb"] or x.gb then its corresponding elements with [][]
              }
          }
          console.log(x["isValid"]); //isValid is the key, the value is a boolean true/false
        }
    });
