call C dll from C# complex structure - c#

I have c dll came from outside of our group.
#pragma pack(push, 8)
typedef struct
{
int int1;
int int2;
int int3;
int int4;
int int5;
int int6;
int int_array1[250];
int int_array2[250];
int int_array3[250];
int int_array4[250];
int int_array5[250];
int int_array6[250];
}my_structure
#pragma pack(pop)
extern "C" {
__declspec(dllexport) void set_my_structure(my_structure mystruct);
__declspec(dllexport) my_structure get_my_structure();
}
I am using the following code to call the dll from C#.
[StructLayout(LayoutKind.Sequential, Pack = 8)]
public class MyStructure
{
public int int1;
public int int2;
public int int3;
public int int4;
public int int5;
public int int6;
public int[] int_array1 = new int[250];
public int[] int_array2 = new int[250];
public int[] int_array3 = new int[250];
public int[] int_array4 = new int[250];
public int[] int_array5 = new int[250];
public int[] int_array6 = new int[250];
}
[DllImport(_dllName, EntryPoint = "set_my_structure", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi, ExactSpelling = true)]
public static extern void SetMyStructure(MyStructure data);
[DllImport(_dllName, EntryPoint = "get_my_structure", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi, ExactSpelling = true)]
public static extern MyStructure GetMyStructure();
However, the code throws exception and stuck in neutral gear when I call GetMyStructure method. What is wrong? What is the best approach to handle this?

How to deal with "no set size" arrays in pinvoke structs?

How would you write this type of struct in c#?
struct _JOBOBJECT_BASIC_PROCESS_ID_LIST {
DWORD NumberOfAssignedProcesses;
DWORD NumberOfProcessIdsInList;
ULONG_PTR ProcessIdList[1];
}
sins there is no set size for the ProcessIdList array, what do you do? Do you just write it like this:
[StructLayout(LayoutKind.Sequential)]
struct JOBOBJECT_BASIC_PROCESS_ID_LIST
{
int NumberOfAssignedProcesses;
int NumberOfProcessIdsInList;
IntPtr ProcessIdList; //Must point to a allocated array, thanks jdweng for letting me know.
}
or do you just assign a size which is big enough, e.g.:
[StructLayout(LayoutKind.Sequential)]
struct JOBOBJECT_BASIC_PROCESS_ID_LIST
{
int NumberOfAssignedProcesses;
int NumberOfProcessIdsInList;
[MarshalAs(UnmanagedType.ByValArray, SizeConst = MAX_PATH)]
UIntPtr[] ProcessIdList; //Works just fine, but is limited to the SizeConst.
}

This sort of structure is usually declared (there are others like this one in WLan APIs for example) :
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
public struct JOBOBJECT_BASIC_PROCESS_ID_LIST
{
public int NumberOfAssignedProcesses;
public int NumberOfProcessIdsInList;
public IntPtr[] ProcessIdList;
public JOBOBJECT_BASIC_PROCESS_ID_LIST(IntPtr pList)
{
int nIntSize = Marshal.SizeOf<int>(); // 4
NumberOfAssignedProcesses = Marshal.ReadInt32(pList, 0);
NumberOfProcessIdsInList = Marshal.ReadInt32(pList, nIntSize);
ProcessIdList = new IntPtr[NumberOfProcessIdsInList];
for (int i = 0; i < NumberOfProcessIdsInList; i++)
{
IntPtr pItemList = IntPtr.Zero;
if (Marshal.SizeOf<IntPtr>() == 4)
pItemList = new IntPtr(pList.ToInt32() + (i * Marshal.SizeOf<IntPtr>()) + (nIntSize * 2));
else
pItemList = new IntPtr(pList.ToInt64() + (i * Marshal.SizeOf<IntPtr>()) + (nIntSize * 2));
IntPtr nPID = new IntPtr();
nPID = Marshal.ReadIntPtr(pItemList, 0);
ProcessIdList[i] = nPID;
}
}
}

I think any of the ways you mentioned should work.
In addition, there is a matching feature in c#: Define an array with the fixed keyword:
struct JOBOBJECT_BASIC_PROCESS_ID_LIST
{
int NumberOfAssignedProcesses;
int NumberOfProcessIdsInList;
fixed IntPtr ProcessIdList[1];
}
See documentation:
https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/unsafe-code-pointers/fixed-size-buffers
Also no bounds check, so you should be able to read behind the end of the struckt easily:
Note
Except for memory created by using stackalloc, the C# compiler and the common language runtime (CLR) do not perform any security buffer overrun checks. As with all unsafe code, use caution.

How to call WFSStartUp via C# application

I use this code for call WFSStartUp via C# program
[StructLayout(LayoutKind.Sequential, Pack = 1, CharSet = CharSet.Ansi)]
public unsafe struct WFSVERSION
{
public ushort wVersion;
public ushort wLowVersion;
public ushort wHighVersion;
public fixed char szDescription[256 + 1];
public fixed char szSystemStatus[256 + 1];
}
[DllImport("msxfs.dll", CharSet = CharSet.Ansi, CallingConvention = XFSConstants.CALLINGCONVENTION)]
public static extern int WFSStartUp(int dwVersionsRequired, ref WFSVERSION lpWFSVersion);
WFSVERSION m_Version = new WFSVERSION();
int requestVersion = 0x00010202;
int hResult = WFSStartUp(requestVersion, ref m_Version);
the return value hResult is Ok but m_Version.szDescription not correct (m_Version.szDescription[0] = 'W', m_Version.szDescription[1] = 0, ...)
How to solve this problem?

Marshalling array of structures from c++ to c# in WinCE

I'm trying to Marshal the following structures from c++ to c# on a Windows CE program and compact framework 2.0. I'm having a lot of difficulties with the marshalling of strings.
I have this c++ code:
#define Console_Parameters_MAX 50
struct AllParameters {
Parameter Parameters[Console_Parameters_MAX];
} ;
struct Parameter {
int Index;
int Id;
char Value[20];
};
extern "C" {
BOOL GetAllConsoleParameters(AllParameters *pItem);
}
and this are the corresponding c# code:
[StructLayout(LayoutKind.Sequential)]
public struct AllParameters {
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 50)]
public Parameter[] Parameters
}
[StructLayout(LayoutKind.Sequential)]
public struct Parameter {
public int Index;
public int Id;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 20)]
public byte[] Value;
}
[DllImport("exemple.dll", SetLastError = true)]
public static extern bool GetAllConsoleParameters([MarshalAs(UnmanagedType.Struct)] ref AllParameters pItem);
and this is how I invoke it:
AllParameters item = new AllParameters();
if (AppAPI.GetAllConsoleParameters(ref item)) {
var array = item.Parameters;
}
When I call the GetAllConsoleParameters I get exception NotSupportedException. I've tried many configurations but with no success.
Can anyone advise on how to achieve it?
Thanks in advance

This works for me on a Windows Desktop. You might have to change the calling convention to Cdecl in the C DLL and the C# DllImport attribute, because I read here that Cdecl is standard on Windows CE: https://msdn.microsoft.com/en-us/library/system.runtime.interopservices.callingconvention(v=vs.110).aspx
C code:
extern "C" {
__declspec(dllexport) BOOL __stdcall GetAllConsoleParameters(AllParameters *pItem)
{
pItem->Parameters[0].Index = 0;
pItem->Parameters[0].Id = 42;
CopyMemory(&pItem->Parameters[0].Value[0], "Hello World", 12);
pItem->Parameters[1].Index = 1;
pItem->Parameters[1].Id = 43;
CopyMemory(&pItem->Parameters[1].Value[0], "Hello World 43", 15);
return TRUE;
}
}
C# code:
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
struct Parameter
{
int Index;
int Id;
//char Value[20];
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 20)]
string Value;
};
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
struct AllParameters
{
//Parameter Parameters[Console_Parameters_MAX];
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 50)]
Parameter[] Parameters;
};
class Program
{
[DllImport("MarshalC.dll", CallingConvention = CallingConvention.StdCall)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool GetAllConsoleParameters(ref AllParameters pItem);
static void Main(string[] args)
{
var size = Marshal.SizeOf<AllParameters>();
AllParameters all = new AllParameters();
bool result = GetAllConsoleParameters(ref all);
}
}

I would do it like this
[StructLayout(LayoutKind.Sequential)]
public struct AllParameters {
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 50)]
public Parameter[] Parameters;
}
[StructLayout(LayoutKind.Sequential)]
public struct Parameter {
public int Index;
public int Id;
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 20)]
public byte[] Value;
}
[DllImport("exemple.dll", SetLastError = true, CallingConvention = CallingConvention.Cdecl)]
public static extern bool GetAllConsoleParameters(ref IntPtr pItem);
static void Main(string[] args)
{
AllParameters allParameters = new AllParameters();
allParameters.Parameters = new Parameter[50];
IntPtr ptr = Marshal.AllocHGlobal(Marshal.SizeOf(allParameters));
int z = Marshal.SizeOf(allParameters);
if (GetAllConsoleParameters(ref ptr))
{
Marshal.PtrToStructure(ptr, allParameters);
Parameter[] parameters = allParameters.Parameters;
}
}

following my solution, c++ code:
/* - not used
#define Console_Parameters_MAX 50
struct AllParameters {
Parameter Parameters[Console_Parameters_MAX];
} ;
*/
struct Parameter {
int Index;
int Id;
char Value[20];
};
extern "C" {
BOOL GetAllConsoleParameters(Parameter pItem[], int size);
}
and corresponding c# code:
/* - not used
[StructLayout(LayoutKind.Sequential)]
public struct AllParameters {
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 50)]
public Parameter[] Parameters
}
*/
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
public struct Parameter {
public int Index;
public int Id;
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 20)]
public byte[] Value;
}
[DllImport("exemple.dll", SetLastError = true, CharSet = CharSet.Unicode)]
public static extern bool GetAllConsoleParameters([MarshalAs(UnmanagedType.LPArray, SizeParamIndex = 1), Out] ConsoleParameter[] myStruct, int size);
and code invoke:
ConsoleParameter[] item = new ConsoleParameter[50];
if (AppAPI.GetAllConsoleParameters(item, 50)) {
var array = item;
}
thanks a lot for help

Access Violation Error when calling a function with struct parameter from C-DLL in C#

I got following definition for a function in a c-based DLL (no source available):
uint MakeReference(MemBlock* ipReferenceMemBlock);
MemBlock is defined as:
typedef struct {
HANDLE_TAG dTag;
long dLength;
BYTE* dpReference;
} MemBlock;
HANDLE_TAG is defined as:
typedef char HANDLE_TAG[10 + 1];
My take on this in a C# Wrapper Class is:
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct MemBlock
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 11)]
public string dTag;
public uint dLength;
[MarshalAs(UnmanagedType.LPStr)]
public string dpReference;
}
[DllImport("lib.dll", CharSet = CharSet.Ansi, EntryPoint = "MakeReference#24", CallingConvention = CallingConvention.StdCall)]
public static extern uint MakeReference(ref IntPtr pDDipMemBlock);
public static uint FAPIMakeReference(ref MemBlock ipMemBlock)
{
uint error = 0;
IntPtr pDDipMemBlock = Marshal.AllocHGlobal(Marshal.SizeOf(ipMemBlock));
try
{
Marshal.StructureToPtr(ipMemBlock, pDDipMemBlock, false);
error = MakeReferenceEx(ref pDDipMemBlock);
ipMemBlock = (MemBlock)Marshal.PtrToStructure(pDDipMemBlock, typeof(MemBlock));
}
finally
{
Marshal.FreeHGlobal(pDDipMemBlock);
}
return error;
}
calling this with:
MemBlock refMemBlock = new MemBlock();
uint error = MakeReferenceEx(ref refMemBlock);
resulting in an Access Violation Expection
