Question

我必须在vb.net将数据表转换为JSON格式。我已经为此编写了代码，但是，我想要另一种格式。我添加了dll NewtonSoft.json并从数据库填充数据表，我写的代码...... ''''我的dt充满了数据。我在Web服务中编写了代码

Dim jsonString As String = JsonConvert.SerializeObject(dt)

我得到的结果如 -

{"people":[{"ref":"108414","first_name":"George","last_name":"Buss","display_name":"George Buss","title":"Director of Experience & Education","organization_name":"Minnetrista","bio":"","address":"","city":null,"state":"IN","zipcode":"","country":"United States","phone_work":"","email":"","website":"","tags":"[Speaker,Attendees]","presenter_at":"[2307,8976]","organization_ref":"36441"}] }

但"tags"值"[Speaker,Attendees]"取代我需要的值 "tags":["Speaker","Attendees"]和presenter_at也相同

从我的代码中我直接获取数据并将其转换为json。但为此，我认为要修改json数据，因为这些数据不是静态的，而是来自数据库。而且我会逐个改变。有谁知道解决方案，请帮助我。谢谢你提前。

 public string DataTableToJSONWithJavaScriptSerializer(DataTable table)
        {
            JavaScriptSerializer jsSerializer = new JavaScriptSerializer();
            List<Dictionary<string, object>> parentRow = new List<Dictionary<string, object>>();
            Dictionary<string, object> childRow;
            foreach (DataRow row in table.Rows)
            {
                childRow = new Dictionary<string, object>();
                foreach (DataColumn col in table.Columns)
                {
                    childRow.Add(col.ColumnName, row[col]);
                }
                parentRow.Add(childRow);
            }
            return jsSerializer.Serialize(parentRow);
        }

此方法返回json字符串。我希望它对你有帮助。
