There is some structure converted from C in C #, as the library (DLL) is written on C, but it is necessary to use it in the project on C #.

In C # I am trying to initialize this structure:
datartk.rtksvr_t rtksvr;
Int Isizertksrv;
INTPTR RTKSRV_PTR;
Try.
{
isizertksrv = marshal.sizeof (Typeof (datartk.rtksvr_t));
}
Catch (ArgumentException EX)
{
STRING STRERR = EX.MESSAGE;
}
Catch (TypeLoadException EX)
{
STRING STRERR = EX.MESSAGE;
}
Try.
{
RTKSRV_PTR = Marshal.Alloccotaskmem (Isizertksrv);
}
Catch (ArgumentException EX)
{
STRING STRERR = EX.MESSAGE;
}
Datartk.rtksvr_t RTKSRV = (Marshal.ptrtostructure (RTKSRV_PTR, TYPEOF (DatartK.Rtksvr_t)));
When trying to find out the size issues the System.ArgumentException error with the following post:
type ‘realtimemonitor.datartk + RTKSVR_T’ CANNOT BE MARSHALED AS AN
UNMANAGED STRUCTURE; No Meaningful Size Or Offset Can Be Computed.
From useful can be stack:
at system.runtime.interopservices.marshal.sizeofhelper (Type T, Boolean ThrowifnotMarshalable)
at system.runtime.interopservices.marshal.sizeof (Type T)
At RealtimeMonitor.StreamHub. & LT; WriteItems & GT; D__139.MoveNext () In C: \ Users \ Zharkov.v \ Source \ Repos \ RealtimeMonitor \ ReiltimeMonitor \ StreamHub.cs: Line 138
I understand that it cannot create an object, but still I can not understand what’s the matter or can I go wrong. No memory is also issued an error that is not enough memory, so I rewrote to this option.
Who can tell me what I do wrong?

gives this
Cannot Marshal Field ‘Half_Cyc’ Of Type ‘Raw_t’: The Type Definition
Of this Field Has Layout Information But Has An Invalid
Managed / unmanaged Type Combination or is unmashalable.
Answer 1, Authority 100%
at least, this item looks erroneous:
[Marshalas, SizeConst = 18)] / * Solution Options Type * /
Public int POSF;
Managed type int, and uncontrollable – array?
In addition, you have many other inconsistencies that, although they cannot lead to this error, but because of them the code will not work correctly. For example, in an unmanaged structure:
unsigned char * buff [3];
This is an array of three pointers to bytes
In managed:
[Marshalas (Unmanagedtype.byvalarray, SizeConst = 3)]
Public Byte [] buff;
This is an array of three bytes (values). They are not equivalent. Check all your structures that they correctly use types in accordance with the recommendations MarsHaling Data with Platform Invoke .
Answer 2
did not count the previous answer, as the answer, since it is too common. And he himself has already corrected such mistakes before the response appears. Well, now in order.
error №1
In the Solopt_t structure, we delete the [Marshalas, SizeConst = 18)] line before describing the structure elements.
error number 2
In the structure of exterr_t we replace Public Double Cerr; / * Code Errors (M) * / on Public Double [] Cerr; / * Code Errors (M) * / , since it is worth [MarshalaSA, SizeConst = 4 NFREQ 2)]
error №3
In the structure of Raw_t We replace the GTime Tobs string on GTime [] Tobs – the reason for the same
error №4
In the structure of obsd_t We replace the double L line on double [] l … Well, you already understood)))
error №5
In the structure RAW_T I replace the lexeph_t lexeph string on lexeph_t [] lexeph .
Error №6
In the structure of Raw_t We replace the SBSION_T SBSion line on sbsion_t [] SBSion .
error number 7
The most difficult, I was looking for another place, but it turned out …
Delete a string before starting the description of the [Marshalas, Unmanagedty.byvalarray, SizeConst = 7)]
error number 8
Structure RTKSVR Replace sbsmsg_t sbsmsg on sbsmsg_t [] sbsmsg .
error №9
Structure RTKSVR Replace OBS_T OBS on OBS_T [] OBS .
error number 10
Structure RTKSVR Replace Stream_t OBS on Stream_t [] OBS .
could be counted and the previous answer could be counted, but I corrected these mistakes, which he says, but not corrected that they are not specified in it and about the conformity of the types P / Invoke – not at the wrong side, since it is very I had to reread a lot.
PS Thank you very much to my friends from Pavlodar, Karaganda and especially Taganrog for invaluable assistance in solving this issue and not only.
