我在C#中有一个类似以下的字符串。我需要遍历并创建HTML表输出。我尝试使用JSON.NET,但无法弄清楚如何检索键(名称,年龄和工作)。
string data = "{items:[ {'Name':'AAA','Age':'22','Job':'PPP'} ,{'Name':'BBB','Age':'25','Job':'QQQ'} ,{'Name':'CCC','Age':'38','Job':'RRR'}]}";
表格格式为
.................................. | 姓名| 年龄| 工作机会 .................................. | AAA | 22 | PPP | .................................. | BBBB | 25 | QQQ | .................................. | CCC | 28 | $$ | ..................................
任何帮助将不胜感激。
Dave提供的代码在这里是理想的解决方案..但是它适用于.NET 4.0 ..我已经将JSON.NET和以下代码用于.NET 3.5
使用Newtonsoft.Json.Linq;
string jsonString = "{items:[{'Name':'Anz','Age':'29','Job':''},{'Name':'Sanjai','Age':'28','Job':'Developer'},{'Name':'Rajeev','Age':'31','Job':'Designer'}]}"; JObject root = JObject.Parse(jsonString); JArray items = (JArray)root["items"]; JObject item; JToken jtoken; for (int i = 0; i < items.Count; i++) //loop through rows { item = (JObject)items[i]; jtoken = item.First; while (jtoken != null)//loop through columns { Response.Write(((JProperty)jtoken).Name.ToString() + " : " + ((JProperty)jtoken).Value.ToString() + "<br />"); jtoken = jtoken.Next; } }
您可以使用.NET 4的动态类型和内置的JavaScriptSerializer来实现。可能是这样的:
string json = "{\"items\":[{\"Name\":\"AAA\",\"Age\":\"22\",\"Job\":\"PPP\"},{\"Name\":\"BBB\",\"Age\":\"25\",\"Job\":\"QQQ\"},{\"Name\":\"CCC\",\"Age\":\"38\",\"Job\":\"RRR\"}]}"; var jss = new JavaScriptSerializer(); dynamic data = jss.Deserialize<dynamic>(json); StringBuilder sb = new StringBuilder(); sb.Append("<table>\n <thead>\n <tr>\n"); // Build the header based on the keys in the // first data item. foreach (string key in data["items"][0].Keys) { sb.AppendFormat(" <th>{0}</th>\n", key); } sb.Append(" </tr>\n </thead>\n <tbody>\n"); foreach (Dictionary<string, object> item in data["items"]) { sb.Append(" <tr>\n"); foreach (string val in item.Values) { sb.AppendFormat(" <td>{0}</td>\n", val); } } sb.Append(" </tr>\n </tbody>\n</table>"); string myTable = sb.ToString();
最后,myTable将包含一个如下所示的字符串:
myTable
<table> <thead> <tr> <th>Name</th> <th>Age</th> <th>Job</th> </tr> </thead> <tbody> <tr> <td>AAA</td> <td>22</td> <td>PPP</td> <tr> <td>BBB</td> <td>25</td> <td>QQQ</td> <tr> <td>CCC</td> <td>38</td> <td>RRR</td> </tr> </tbody> </table>
