Deserialise complicated Jason data

AndieDu

Dear all, I have this jason data that ready to be serialised: (Indention added for readability)

{"Error":"",
"UserMeasurements":
[{ "MeasurementName":"BloodPressure",
"ClinicalDatas":
[{"Name":"Systolic",
"Unit":"mmHg ",
"ClinicalDataPoints":[[1304197968110,149],[1304290213920,145],[1304369712717,159],[1304459900650,160],
[1304542964530,176],[1304564292340,147],[1304649916767,141],[1304726125653,139],[1304826583873,156],
[1304880946500,167],[1305069333890,152]]},
{"Name":"Diastolic",
"Unit":"mmHg ",
"ClinicalDataPoints":[[1304197968220,129],[1304290215047,92],[1304369712763,91],[1304459900900,105],
[1304542965530,83],[1304564292403,103],[1304649916797,81],[1304726125687,133],[1304826584000,85],
[1304880946547,108],[1305069334890,89]]},
{"Name":"Mean Blood Pressure",
"Unit":"mmHg ",
"ClinicalDataPoints":[]}
]
}
]
}";

and I have these c# code to deserialised it:

namespace Json
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
JavaScriptSerializer js = new JavaScriptSerializer();
string test = "{\"Error\":\"\",\"UserMeasurements\":[{\"MeasurementName\":\"BloodPressure\",\"ClinicalDatas\":[{\"Name\":\"Systolic\",\"Unit\":\"mmHg \",\"ClinicalDataPoints\":[[1304197968110,149],[1304290213920,145],[1304369712717,159],[1304459900650,160],[1304542964530,176],[1304564292340,147],[1304649916767,141],[1304726125653,139],[1304826583873,156],[1304880946500,167],[1305069333890,152]]},{\"Name\":\"Diastolic\",\"Unit\":\"mmHg \",\"ClinicalDataPoints\":[[1304197968220,129],[1304290215047,92],[1304369712763,91],[1304459900900,105],[1304542965530,83],[1304564292403,103],[1304649916797,81],[1304726125687,133],[1304826584000,85],[1304880946547,108],[1305069334890,89]]},{\"Name\":\"Mean Blood Pressure\",\"Unit\":

The property appears to be called 'ClinicalDatas' (not UserClinicalDatas) in the JSON. Regarding the names, 'data' is already plural, so using 'datas' just looks wrong. If you are in charge of both ends of this serialisation you should change that.

right on the spot, Bob, and amazingly, i didnt spot out this subtle thing, thanks heaps anyway.

Try a tool for generating your classes from the Json data, e.g. http://json2csharp.com/[^]. That will prevent typos.
