无法通过SSIS使用JSON

Question

我正在尝试使用SSIS中的脚本组件使用JSON。我正在尝试从此处获取数据：https://api.opendota.com/api/teams 不幸的是，在我执行程序包之后，它只给我第一行数据。

#region Class
[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{
    /// <summary>Outputs records to the output buffer</summary>
    public override void CreateNewOutputRows()
    {


        //Set Webservice URL
        string wUrl = "https://api.opendota.com/api/teams?json";

        try
        {

            RootObject[] Teams = GetWebServiceResult(wUrl);

            //For each group of metrics output records
            foreach (var metric in Teams)
            {
                Output0Buffer.AddRow();
                Output0Buffer.teamid = metric.team_id;
                Output0Buffer.rating = metric.rating;
                Output0Buffer.wins = metric.wins;
                Output0Buffer.losses = metric.losses;
                Output0Buffer.lastmatchtime = metric.last_match_time;
                Output0Buffer.name = metric.name;
                Output0Buffer.tag = metric.tag;
                Output0Buffer.logourl = metric.logo_url;
            }

        }
        catch (Exception e)
        {
            FailComponent(e.ToString());
        }

    }

/// <summary>

    private RootObject[] GetWebServiceResult(string wUrl)
    {

        HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create(wUrl);
        HttpWebResponse httpWResp = (HttpWebResponse)httpWReq.GetResponse();
        RootObject[] jsonResponse = null;

        try
        {
            //Test the connection
            if (httpWResp.StatusCode == HttpStatusCode.OK)
            {

                Stream responseStream = httpWResp.GetResponseStream();
                string jsonString = null;

                //Set jsonString using a stream reader
                using (StreamReader reader = new StreamReader(responseStream))
                {
                    jsonString = reader.ReadToEnd();
                    reader.Close();
                }

                //Deserialize our JSON
                JavaScriptSerializer sr = new JavaScriptSerializer();


                jsonResponse = sr.Deserialize<RootObject[]>(jsonString);

            }
            //Output connection error message
            else
            {
                FailComponent(httpWResp.StatusCode.ToString());

            }
        }
        //Output JSON parsing error
        catch (Exception e)
        {
            FailComponent(e.ToString());
        }
        return jsonResponse;

    }

    /// <summary>

    private void FailComponent(string errorMsg)

        IDTSComponentMetaData100 compMetadata = this.ComponentMetaData;
        compMetadata.FireError(1, "Error Getting Data From Webservice!", errorMsg, "", 0, out fail);

    }

我唯一能想到的是JSON开头以[]结尾，我真的不确定bot。

我找到的关于类似问题的唯一答案是：

实际上我确实可以使用它。问题与JSON或Class无关，而在于每次调用仅返回一条记录这一事实。我干脆摆脱了For Each循环，嘿，很容易

但不确定如何使它们互不相干。
