pcapDotNet.Core.Dllファイルで定義されたクラスを使用するユーザー定義関数を作成しようとしています。私のC＃のコードは以下の通りです：pcap dllファイルをC＃プロジェクトに埋め込みました。

{
class Program1
{
/*

}*/
public Program1()
{
AppDomain.CurrentDomain.AssemblyResolve += ResolveAssembly;
}
static Assembly ResolveAssembly(object sender, ResolveEventArgs args)
{
String dllName = new AssemblyName(args.Name).Name + ".dll";
var assem = Assembly.GetExecutingAssembly();
String resourceName = assem.GetManifestResourceNames().FirstOrDefault(rn => rn.EndsWith(dllName));
if (resourceName == null) return null; // Not found, maybe another handler will find it
using (var stream = assem.GetManifestResourceStream(resourceName))
{
Byte[] assemblyData = new Byte[stream.Length];
stream.Read(assemblyData, 0, assemblyData.Length);
return Assembly.Load(assemblyData);
}
}

public static int checkFunction()
{
Program1 worker1 = new Program1();
worker1.checkDevice();
return 0;
}
void checkDevice()
{
// Retrieve the interfaces list
IList<LivePacketDevice> allDevices = LivePacketDevice.AllLocalMachine;
Console.WriteLine(" inside checkDevice\n");
// Scan the list printing every entry
for (int i = 0; i != allDevices.Count(); ++i)
DevicePrint(allDevices[i]);
}
// Print all the available information on the given interface
private static void DevicePrint(IPacketDevice device)
{
// Name
Console.WriteLine(device.Name);
// Description
if (device.Description != null)
Console.WriteLine("\tDescription: " + device.Description);
// Loopback Address
Console.WriteLine("\tLoopback: " +
(((device.Attributes & DeviceAttributes.Loopback) == DeviceAttributes.Loopback)
? "yes"
: "no"));
// IP addresses
foreach (DeviceAddress address in device.Addresses)
{
Console.WriteLine("\tAddress Family: " + address.Address.Family);
if (address.Address != null)
Console.WriteLine(("\tAddress: " + address.Address));
if (address.Netmask != null)
Console.WriteLine(("\tNetmask: " + address.Netmask));
if (address.Broadcast != null)
Console.WriteLine(("\tBroadcast Address: " + address.Broadcast));
if (address.Destination != null)
Console.WriteLine(("\tDestination Address: " + address.Destination));
}
Console.WriteLine();
}
}
}
私のPythonコードは以下の通りです：
class gooseDriver():
"""A class that creates windows form by importing IED.MainWindow()"""
def __init__(self, ipAddress, port):
self.hllDll = WinDLL (r"C:\WORK\IEC61850\gooseThread1\gooseThread1\bin\x64\Debug\gooseThread1.dll")
self.hllDll.checkFunction()
print("Goose Message Started\n")
def main():
IED = gooseDriver("192.168.0.20", 102)
print("GooseDriver is called\n")
if __name__ == '__main__':
main()
私はOSErrorの「などのエラーを与えることのpythonからcheckFunctionを呼び出すしようとしたとき：[WinError -532462766] Windowsエラー0xe0434352 "これは、関数がpcapファイルからLivePacketsDeviceクラスを使用しているためです。私は参照としてDLLを生成しながらpcapDotNet.Core.Dllファイルを埋め込んでいます。誰でもこの問題の解決策を教えてください。
