Convert TL Language (mtproto) type to C#

Question

I am using tl-language compiler to compile schema of Telegram Api TL language described in https://core.telegram.org/mtproto in C#

There is a compiler that compile tl-language to C# classes https://github.com/everbytes/SharpTL.Compiler

But it can compile new telegram schema at this line:

"params":[
    {"name":"flags","type":"#"},
    {"name":"report_spam","type":"flags.0?true"}]
,"type":"PeerSettings"}

And it compile it to wrong code:

[TLObject(0x818426CD)]
public partial class PeerSettings : IPeerSettings
{
    [TLProperty(1)]
    public I# Flags { get; set; }

    [TLProperty(2)]
    public IFlags0?true ReportSpam { get; set; }

}

Is there any solution in casting in C# codes?

I do not know what is type of this "flags:#" in C#

This type "#" described in https://core.telegram.org/mtproto/TL-formal

user {flags:#} id:flags.0?string first_name:flags.1?string last_name:flags.2?string reserved3:flags.3?False reserved4:flags.4?False = User flags;

In the future, bits 3 and 4 in the flags field may be used to transmit new fields after changing the names and types of the reserved3 and reserved4 fields

It seems like the property is an enumerable of IFlags: "public IFlags { get; set; }" given "#" seems to define the set of IFlag types/values. — Ryan Peters, May 25 '16 at 10:27
flag# is integer type used as a flag to indicate which flagged-fields are present (on receiving) or which flagged-fields you are including(on sending) — Charles Okwuagwu, Jun 16 '16 at 07:29

peerSettings#818426cd flags:# report_spam:flags.0?true = PeerSettings

deep searching around this I think this hash (#) means that dynamic value of variable, in some cases it can be true or false, another cases it can be a sequence of integers nonnegative:

matrix {X:Type} m:# n:# a:(%Tuple (%Tuple X m) n) = Matrix X;

above we got the M and N taking a integer random value > 0

get_users req_fields:# ids:%(Vector int) = Vector %(User req_fields)

in this another case it can assume a conditional value
req_fields variable is cast only to User object, but in other cases it could be casted
to another kind of object.

maybe the correct way of this TLObject in c# is :

[TLObject(0x818426CD)]
public partial class PeerSettings : IPeerSettings
{
    [TLProperty(1)]
    public int Flags { get; set; }

    [TLProperty(2)]
    public bool ReportSpam { get; set; }

}

apologises my english is rusty
