I've successfully created code that serializes a complex javascript object and posts it to an ASP.NET page. I can get the JSON string using Request.Form and the result looks like this (I've added indentation for readability):
{
"gasterPerStolPerVecka": {
"name": "gasterPerStolPerVecka",
"keyValue_id": "2",
"set_id": "1",
"containerElement": "#gasterPerStolPerVecka",
"keyValueComponents": [
{
"name": "gasterPerStolPerVecka_guestsPerWeek",
"value": "200"
},
{
"name": "gasterPerStolPerVecka_numberOfChairs",
"value": "100"
}
],
"keyValueUnitText": "gäster/stol per vecka",
"keyValueCalculationMethod": "divide",
"isValid": true,
"result": 2
},
"tillgangligaStolstimmarPerVecka": {
"name": "tillgangligaStolstimmarPerVecka",
"keyValue_id": "1",
"set_id": "1",
"containerElement": "#tillgangligaStolstimmarPerVecka",
"keyValueComponents": [
{
"name": "tillgangligaStolstimmarPerVecka_openHoursPerWeek",
"value": "35"
},
{
"name": "tillgangligaStolstimmarPerVecka_numberOfChairs",
"value": "100"
}
],
"keyValueUnitText": "stolstimmar/vecka",
"keyValueCalculationMethod": "multiply",
"isValid": true,
"result": 3500
},
"planeradIntaktPerTillgangligStolOchVecka": {
"name": "planeradIntaktPerTillgangligStolOchVecka",
"keyValue_id": "",
"set_id": "",
"containerElement": "#planeradIntaktPerTillgangligStolOchVecka",
"keyValueComponents": [

},
{

"value": "100"
}
],
"keyValueUnitText": "kr",
"keyValueCalculationMethod": "divide",

"result": null,
"errorText": "Ofullständigt underlag för beräkning."
},
"planeradIntaktPerTillgangligaStolstimmar": {

"keyValue_id": "",
"set_id": "",
"containerElement": "#planeradIntaktPerTillgangligaStolstimmar",
"keyValueComponents": [
{
"name": "planeradIntaktPerTillgangligaStolstimmar_weeklyRevenue",
"value": ""
},
{

"value": "35"
},
{
"name": "planeradIntaktPerTillgangligaStolstimmar_numberOfChairs",
"value": "100"
}
],
"keyValueUnitText": "kr",
"keyValueCalculationMethod": "divide_divide",
"isValid": false,
"result": null,
"errorText": "Ofullständigt underlag för beräkning."
}
}
Now I try to deserialize this on the server side, but it's difficult. I keep getting the error:
[NullReferenceException: Object reference not set to an instance of an object.]
I don't know where to start looking for errors?
Thanks in advance! /Thomas Kahn
use stringify instead serialization
You need to use a deserialization library for ASP.NET. See http://json.org/ for libraries that are available or maybe there is one built into ASP.NET. Either way, the code will look like:
String s = getAppropriateFormField();
Object o = JSONLibraryPackage.parse(s);
where obviously you'll have to fill in the blanks for how you get the form field and then what package and method does the parsing.
