I have a string like the following in C#. I need to loop through and create an HTML table output. I tried with JSON.NET but couldn't figure out how to retrieve the keys (Name, Age & Job).
string data = "{items:[
{'Name':'AAA','Age':'22','Job':'PPP'}
,{'Name':'BBB','Age':'25','Job':'QQQ'}
,{'Name':'CCC','Age':'38','Job':'RRR'}]}";
The table format is
......................... | Name | Age | Job | ......................... | AAA | 22 | PPP | ......................... | BBBB | 25 | QQQ | ......................... | CCC | 28 | RRR | .........................
Any help will be greatly appreciated.
The code provided by Dave is the ideal solution here.. but it work for .NET 4.0.. I have used following code with JSON.NET for .NET 3.5
using 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;
}
}
You can use .NET 4's dynamic type and built-in JavaScriptSerializer to do that. Something like this, maybe:
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();
At the end, myTable will hold a string that looks like this:
<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>
