I had to write many dozens of lines of code (see here: https://dotnetfiddle.net/RiVx2E) to generate a few lines of sample data.
In this specific case I could manually export the output variable (see the whole code on Fiddler) in this way:
new List {
{ IDMacroTab = 1, IDTab = 1, IDSIot = 2 }
{ IDMacroTab = 1, IDTab = 2, IDSIot 1}
{ IDMacroTab = 1, IDTab = 2, IDSIot = 2}
{ IDMacroTab = 1, IDTab = 2, IDSIot = 3}
{ IDMacroTab = 2, IDTab = 1, IDSIot = 1}
{ IDMacroTab = 2, IDTab = 1, IDSIot = 2 }
{ IDMacroTab = 2, IDTab = 2, IDSIot = 1}
{ IDMacroTab = 2, IDTab = 2, IDSIot = 2}
{ IDMacroTab = 2, IDTab = 2, IDSIot = 3}
{ IDMacroTab = 3, IDTab = 1, IDSIot = 1}
{ IDMacroTab = 3, IDTab = 1, IDSIot = 2}
{ IDMacroTab = 3, IDTab = 2, IDSIot = 1}
{ IDMacroTab = 3, IDTab = 2, IDSIot = 2}
{ IDMacroTab = 3, IDTab = 2, IDSIot = 3}};
Is there any workaround that allows to serialize an object to the c# lines of code required to populate it?
I've found this question which can be pretty useful but just for some kind of object (i.e. lists)
And also this plugin ObjectExporter (last update 2017; checked at 2018)
