c# - 将Json字符串反序列化为多个输出

我试图将我的De序列化JSON响应中的值返回给不同的输出，但是当我输出它们时，我只会看到RootObject属性。

在SSIS脚本组件中，我创建了以下输出


我声明了以下课程。

public class Application
{
    public int App_ID { get; set; }
    public string App_Ref { get; set; }
    public string Status { get; set; }
    public string Error_Code { get; set; }
    public string Error_Message { get; set; }
    public string Create_Dt { get; set; }
    public string Modify_Dt { get; set; }
    public string Client_Name { get; set; }
    public string Client_Code { get; set; }
    public string Centrelink_Status { get; set; }

}
public class Response
{
    public List<Application> Applications { get; set; }
    public string Current_Dt { get; set; }
    public string Last_App_Dt { get; set; }
    public int Count { get; set; }
    public int Total { get; set; }
}

public class RootObject
{
    public bool Success { get; set; }
    public Response Response { get; set; }

}

我原始的Json Response看起来像这样。

{
  "Success": true,
  "Response": {
    "Applications": [
      {
        "App_ID": 1638486,
        "App_Ref": "Test Example",
        "Status": "Complete",
        "Error_Code": null,
        "Error_Message": null,
        "Create_Dt": "2014-05-14 03:09:01.030 +00:00",
        "Modify_Dt": "2014-05-14 03:10:59.757 +00:00",
        "Client_Name": "Silver Chef",
        "Client_Code": "SLVC01",
        "Centrelink_Status": "Receiving_Logons"
      },
      {
        "App_ID": 1637906,
        "App_Ref": "SME Demo",
        "Status": "Complete",
        "Error_Code": null,
        "Error_Message": null,
        "Create_Dt": "2015-10-08 03:07:26.793 +00:00",
        "Modify_Dt": "2015-10-08 03:23:32.833 +00:00",
        "Client_Name": "Silver Chef",
        "Client_Code": "SLVC01",
        "Centrelink_Status": "Receiving_Logons"
      },
      {
        "App_ID": 1585286,
        "App_Ref": "Test",
        "Status": "Receiving_Logons",
        "Error_Code": null,
        "Error_Message": null,
        "Create_Dt": "2015-12-04 03:12:49.617 +00:00",
        "Modify_Dt": "2015-12-04 03:12:49.617 +00:00",
        "Client_Name": "Silver Chef",
        "Client_Code": "SLVC01",
        "Centrelink_Status": "Receiving_Logons"
      },
      {
        "App_ID": 1585398,
        "App_Ref": "Test",
        "Status": "Receiving_Logons",
        "Error_Code": null,
        "Error_Message": null,
        "Create_Dt": "2015-12-04 03:27:59.023 +00:00",
        "Modify_Dt": "2015-12-04 03:27:59.023 +00:00",
        "Client_Name": "Silver Chef",
        "Client_Code": "SLVC01",
        "Centrelink_Status": "Receiving_Logons"
      },
      {
        "App_ID": 1585400,
        "App_Ref": "Test",
        "Status": "Receiving_Logons",
        "Error_Code": null,
        "Error_Message": null,
        "Create_Dt": "2015-12-04 03:28:22.903 +00:00",
        "Modify_Dt": "2015-12-04 03:28:22.903 +00:00",
        "Client_Name": "Silver Chef",
        "Client_Code": "SLVC01",
        "Centrelink_Status": "Receiving_Logons"
      }
],
    "Current_Dt": "2016-11-11 01:01:01.743 +00:00",
    "Last_App_Dt": "2016-10-03 22:48:56.397 +00:00",
    "Count": 500,
    "Total": 1870
  }
}

该方法已用于发送和接收响应，这似乎正在反序列化而没有错误。我可以输出“成功”属性。

private RootObject GetWebServiceResult(string vAPIUrl)
    {

        string vAPIToken = Variables.APIToken;

        //Create Web Request
        HttpWebRequest apireq = (HttpWebRequest)WebRequest.Create(vAPIUrl);
        apireq.ContentType = "application/json";
        apireq.Method = "POST";

        string jsonPostStr = "{\"Settings\": {\"API_Token\": \"" + vAPIToken + "\"}, \"Payload\": {}}";
        byte[] postString = Encoding.UTF8.GetBytes(jsonPostStr);

        apireq.ContentLength = postString.Length;

        Stream jsonStream = apireq.GetRequestStream();

        jsonStream.Write(postString, 0, postString.Length);
        jsonStream.Close();

        // Get Web Response
        HttpWebResponse apirsp = (HttpWebResponse)apireq.GetResponse();
        RootObject jsonResponse = null;

        Stream jsonRspStream = apirsp.GetResponseStream();
        string apiResponseString = null;

        using (StreamReader reader = new StreamReader(jsonRspStream))
        {
            apiResponseString = reader.ReadToEnd();
            Console.WriteLine(apiResponseString);
            reader.Close();
        }


        JavaScriptSerializer returnJson = new JavaScriptSerializer();

        //var serialJsonStr = returnJson.Serialize(apiResponseString);
        System.Windows.Forms.MessageBox.Show(apiResponseString);

        jsonResponse = returnJson.Deserialize<RootObject>(apiResponseString);

        return jsonResponse;

    }

但是，当我尝试写入Applications输出缓冲区以返回时，我只会看到成功和响应。 （也无法输出对字符串的响应，但是认为这是因为它长于8000个字符）

当我尝试设置每个应用程序的值时，我看到了。

并且我的foreach语句收到以下错误。


  “ foreach语句无法对类型为变量的变量进行操作
  'ScriptMain.Response'因为'ScriptMain.Response'不包含
  “ GetEnumerator”的公共定义”


请帮忙！这让我发疯！我究竟做错了什么？

最佳答案

我认为您要迭代的是Response.Applications：

foreach (Application app in outPutResponse.Response.Applications)
{
    ApplicationBuffer.AddRow();
    ApplicationBuffer.AppID = app.App_ID;
}
