[InvalidOperationException: Invalid operation. The connection is closed.]

我在序列化对象时收到此错误。

 public string SerializeObj(TemplateData obj)
    {
        string data = null;
        try
        {
            JavaScriptSerializer js = new JavaScriptSerializer();
            ** data = js.Serialize(obj); [This is what i am finding issue is][1]**
        }
        catch (InvalidOperationException iopException)
        {
            string exception = iopException.Data.ToString();
            return exception;
        }
        return data;

请注意：当我序列化我的对象时，我没有使用数据库连接。

有人可以建议我如何解决这个问题吗？

当我序列化我的对象时，它将我的类名为TemplateData。

  public List<TemplateData> List(string myKey)
    {
        TemplateBusinessLogic businessLogic = new TemplateBusinessLogic();
        TemplateData templateData = new TemplateData();
        templateData.key = myKey;
            string postKey = businessLogic.SerializeObj(templateData);
        string listUrl = MandrillAutomation.Helper.Config.ConfigManager.ConstantsConfig.GetValue("listUrl");
        string requestContent = HttpRequestUrl(listUrl, "POST", postKey);
        List<TemplateData> listContent = businessLogic.DeserializeObj<List<TemplateData>>(requestContent); // DESERIALIZE OBJECT

        for (int i = 0; i <= listContent.Count-1; i++)
        {
            FileHelper fileHelp = new FileHelper();
            fileHelp.SaveTemplate(listContent[i].name, listContent[i].code);
        }
        //SaveTemplate(listContent);  //Save Templates into desire format

        log.Info(listContent.Count + " Templates avilable" );
        log.Info("[  ");
        log.Info("Templates :" + GetTemplateName(listContent));
        log.Info("  ]");
        foreach (var content in listContent)
        {
            log.Info("Name of Template : " + content.name + " || Slug of Template : " + content.slug + " || in Account : " + myKey);
        }
        return listContent;
    }

我有类TemplateData，如下所示：

 public class TemplateData :DbContext
{
    public string key {get; set;}
    public string name { get; set; }
    public string slug { get; set; }
    public string fromEmail { get; set; }
    public string fromName { get; set; }
    public string subject { get; set; }
    public string code { get; set; }
    public string text { get; set; }
    public string publish { get; set; }
    public string[] labels { get; set; }
    public string created_at{ get; set; }
    public string updated_at { get; set; }
}

我只是从我的DbContext课程中删除了TemplateData。现在没有错误。：）

InvalidOperationException：无效的操作。连接已关闭。在尝试序列化类对象时，在Asp.Net MVC中
