cant not package with fody ?
LegacyWrapper.dll, LegacyWrapper.Common.dll... can not embedded by fody ? if embedded by fody, call exception: The system can't find the specify File
I mean these two dlls cannot be packaged by fody into a single file, must exist in the folder directory ?
when call 64bit unmanaged dll in 32bit applicationï¼ if have pointer related.it will thrown exception: An IntPtr or UIntPtr with an eight byte value cannot be deserialized on a machine with a four byte word size.
public interface pkeyhelper64Dll : IDisposable
{
[LegacyDllMethod(CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi)]
uint GetEditionNameFromId(uint EditionId, out IntPtr EditionName);
}
class Program
{
static IWrapperConfig _configuration = WrapperConfigBuilder.Create().TargetArchitecture(TargetArchitecture.Amd64).Build();
public static void Main(string[] args)
{
IntPtr EditionName;
using (var client = WrapperProxyFactory<pkeyhelper64Dll>.GetInstance(_configuration))
{
var hResult = client.GetEditionNameFromId(0x30, out EditionName);
if (hResult == 0)
{
Console.WriteLine(Marshal.PtrToStringAnsi( EditionName));
}
}
Console.Read();
}
}

This issue is not related to LegacyWrapper, please raise an issue at fody.
uint
You have declared your out parameter as IntPtr, which is 32 bit wide on your system. The dll will return a pointer that is 64 bit wide. This cannot work this way.
so how can I get the pointer value
or it need use unsafe code?
[LegacyDllImport("pkeyhelper.dll")]
public unsafe interface pkeyhelper64Dll : IDisposable
{
[LegacyDllMethod(CallingConvention = CallingConvention.Winapi)]
int GetEditionNameFromId(uint EditionId, void* EditionName);
}
As I don't know how your DLL is built, this would be a nice question for StackOverflow.
this is a windows system dll. call normally under 64 bit assembly:
[DllImport("pkeyhelper.dll", EntryPoint = "GetEditionNameFromId", CharSet = CharSet.Auto)]
public extern static int GetEditionNameFromId1(int EditionId, out UIntPtr EditionName);
[DllImport("pkeyhelper.dll", EntryPoint = "GetEditionNameFromId", CharSet = CharSet.Auto)]
public extern static int GetEditionNameFromId2(int EditionId, out IntPtr EditionName);
public static void Main(string[] args)
{
UIntPtr EditionName1;
var hRes = GetEditionNameFromId1(0x30, out EditionName1);
if (hRes == 0)
{
Console.WriteLine(Marshal.PtrToStringUni(unchecked((IntPtr)(long)(ulong)EditionName1))); //normaol
}
IntPtr EditionName2;
hRes = GetEditionNameFromId2(0x30, out EditionName2);
if (hRes == 0)
{
Console.WriteLine(Marshal.PtrToStringUni(EditionName2)); //normaol
}
}
