I am experiencing an error converting JSON to a strongly-typed class.
My JSON: {"listBoxID":"ctl00_ctl00_MainContentRoot_MainContent_lstBxSettings","sourceItemText":"Horizontal Bar","sourceItemValue":"Horizontal"}
DroppedItem droppedItem = JsonConvert.DeserializeObject<DroppedItem>(json);
/// <summary>
/// Outlines an object which is useful in simplifying how a CormantRadDock is created.
/// Instead of passing in lots of parameters, would rather just pass in an object that the
/// CormantRadDock knows how to interpret.
/// </summary>
[DataContract]
public class DroppedItem
{
private static readonly ILog Logger = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
[DataMember(Name = "sourceItemText")]
public string Text { get; set; }
[DataMember(Name = "sourceItemValue")]
public string Value { get; set; }
[DataMember(Name = "listBoxID")]
public Reports ReportType { get; set; }
public DroppedItem() { }
public DroppedItem(string text, string value, string listBoxID)
{
Logger.DebugFormat("Text: {0}, Value: {1}, slidingPaneTitle: {2}", text, value, listBoxID);
Text = text;
Value = value;
ReportType = DetermineReportType(listBoxID);
}
private Reports DetermineReportType(string listBoxID)
{
if (listBoxID.Contains("lstBxHistorical"))
{
return Reports.HistoricalReport;
}
else if (listBoxID.Contains("lstBxCustom"))
{
return Reports.CustomReport;
}
else
{
return Reports.None;
}
}
}
The issue is with converting listBoxID to ReportType.
Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Error converting value "ctl00_ctl00_MainContentRoot_MainContent_lstBxSettings" to type 'CableSolve.Web.Reports'
It occurs regardless of whether the if statement finds a hit or defaults to the else block. It does not occur if I do not attempt to pass the listBoxID parameter.
I'm missing something here. Are my DataMember names not doing anything? I thought they would map the listBoxID to the correct property.
Change to something like this:
public Reports ReportType { get; set; }
[DataMember(Name = "listBoxID")]
public string listBoxID
{
set
{
ReportType = DetermineReportType(value);
}
}
Because basically, you can convert that string
to a Report
without your helper method. The constructor is not being called on deserialization
