如何从嵌套值中删除双引号和\

我写了一段代码将列表转换为json,但我有一个问题。当我测试web方法时,我发现 " 和 \ 添加到嵌套对象。我想知道如何使用 JavaScriptSerializer() .

var innerResult (linq query to get list of data).toList()
var serializer = new JavaScriptSerializer();
var serializedResult = serializer.Serialize(innerResult);
result = (from value1 in db.Values
          join value2 in db.Values on value1.ParentId equals value2.RecordId
          join value3 in db.Values on value1.RecordId equals value3.ParentId
          where
              value1.ParentId
              == (from va in db.Values where va.Name == formType select va.RecordId).FirstOrDefault()
          orderby value1.RecordId
          select
              new ItemManagementViewModel
                  {
                      FormType = value2.Name,
                      FormControllerID = value1.RecordId,
                      FormControllerName = value1.Name,
                      values = serializedResult
                  }).ToList();
return result;

public class ItemManagementViewModel 
{
    public string FormType { get; set; }
    public long FormControllerID { get; set; }
    public string FormControllerName { get; set; }

    public string values { get; set; }
}
