unable to get data of a Qlik Sense Sheet

[saranya]

I  have an app created in Qlik Sense with few sheets,  Using a .net sdk trying to get data that is used in creating the sheet.

List<Qlik.Sense.Client.SheetObjectViewListContainer> temp1 = new List<Qlik.Sense.Client.SheetObjectViewListContainer>();
foreach (IAppIdentifier appIdentifier in location.GetAppIdentifiers())
{
if (appIdentifier.AppId == AppId)
{
var appIdentifier1 = location.AppWithId(appIdentifier.AppId, noVersionCheck: true);

using (IApp app = location.App(appIdentifier1, noVersionCheck: true))
{
temp1 =app.GetSheetList().Items.ToList();

//temp1 = app.GetTableData

//temp1=app.getObjectData
//NxGetObjectOptions ng = new NxGetObjectOptions();

// temp1 = app.GetTableData().ToList();
// data.Data= temp1[1].Data;

}

}

Tried the above code but nothing worked , Only list of sheets able to get but need to the data that is behind the sheet.
