我尝试将 Pkcs11Interop 库用于我们的机构项目。但问题是，当我尝试从令牌卡中获取价值时，“尝试读取或写入受保护的内存。这通常表明其他内存已损坏”错误来自 Pkcs11Interop。我找不到任何解决方案。请帮助我，提前谢谢你。
项目是用 .Net Framework 4.5 编写的 Windows 窗体应用程序
错误： system.accessviolationexception {"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."}
错误堆栈跟踪：

代码是这样的：
static void Main()
{
try
{
string pkcs11Library = @"C:\Windows\System32\akisp11.dll";
using (var pkcs11 = new Net.Pkcs11Interop.HighLevelAPI40.Pkcs11(pkcs11Library, false, false))
{
LibraryInfo info = pkcs11.GetInfo();
foreach (Slot slot in pkcs11.GetSlotList(false))
{
SlotInfo slotInfo = slot.GetSlotInfo();
if (slotInfo.SlotFlags.TokenPresent)
{
TokenInfo tokenInfo = slot.GetTokenInfo();
Session session = slot.OpenSession(false);
String pin = "*****";
session.Login(CKU.CKU_USER, pin);
// get all objects using empty ObjectAttributes list
List<ObjectHandle> handles = session.FindAllObjects(new List<ObjectAttribute>());
List<CKA> attrs = new List<CKA>();
attrs.Add(CKA.CKA_LABEL);
foreach (ObjectHandle handle in handles)
{
List<ObjectAttribute> oAttrs = session.GetAttributeValue(handle, attrs); **//Error is getting here**
}
session.CloseSession();
}
}
pkcs11.Dispose();
}
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);

catch (Exception ex)

throw ex;
