    text
    copied!<p>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):</p> <pre><code> { "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": [ { "name": "planeradIntaktPerTillgangligStolOchVecka_weeklyRevenue", "value": "" }, { "name": "planeradIntaktPerTillgangligStolOchVecka_numberOfChairs", "value": "100" } ], "keyValueUnitText": "kr", "keyValueCalculationMethod": "divide", "isValid": false, "result": null, "errorText": "Ofullständigt underlag för beräkning." }, "planeradIntaktPerTillgangligaStolstimmar": { "name": "planeradIntaktPerTillgangligaStolstimmar", "keyValue_id": "", "set_id": "", "containerElement": "#planeradIntaktPerTillgangligaStolstimmar", "keyValueComponents": [ { "name": "planeradIntaktPerTillgangligaStolstimmar_weeklyRevenue", "value": "" }, { "name": "planeradIntaktPerTillgangligaStolstimmar_openHoursPerWeek", "value": "35" }, { "name": "planeradIntaktPerTillgangligaStolstimmar_numberOfChairs", "value": "100" } ], "keyValueUnitText": "kr", "keyValueCalculationMethod": "divide_divide", "isValid": false, "result": null, "errorText": "Ofullständigt underlag för beräkning." } } </code></pre> <p>Now I try to deserialize this on the server side, but it's difficult. I keep getting the error: </p> <p><em>[NullReferenceException: Object reference not set to an instance of an object.]</em></p> <p>I don't know where to start looking for errors?</p> <p>Thanks in advance! /Thomas Kahn</p>
