我嘗試爲我們的機構項目使用Pkcs11Interop庫。但問題是,當我嘗試從令牌卡獲取價值時,「嘗試讀取或寫入受保護的內存。這通常表示其他內存已損壞」錯誤是從Pkcs11Interop獲得的。我找不到任何解決方案。請幫助我,提前謝謝你。PDF使用Pkcs11Interop簽名
項目是一個與.Net框架編寫Windows窗體應用程序4.5
錯誤:system.accessviolationexception {"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."}
錯誤堆棧跟蹤:

代碼是這樣的:
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();
}

throw ex;
