问题描述
我想知道是否有人可以在这里提供帮助。我有一个总体上包含5个布局的项目。现在，我正在尝试使用dotnet core编写api，该api使用数据访问功能，而commone则不在此常规范围之内。因此，我将这2个dll添加为程序集引用（它们正在使用dotnet framwork），并在我的api中将其称为类：
[HttpPost("login")]
public IActionResult login(LoginDto user)
{
General.Common.cLoadUserPermission.stcLoginInfo _LI = new cLoadUserPermission.stcLoginInfo();
if (user.UserName.ToLower() == "adminy" && user.Password.ToLower()== "rddddlad91")
{
_LI.LoginError = enmLoginError.enmLoginError_NoError;
_LI.UserID = "d56d79f4-1f06-4462-9ed7-d4292322555d";
_LI.UserName = "مدير سيستم";
_LI.UserLoginName = "adminy";
_LI.PersonelID = Guid.Empty;
_LI.IsSupervisor = false;
GlobalItems.CurrentUserID = _LI.UserID;
GlobalItems.CurrentUserPLE = _LI.UserLoginName;
GlobalItems.CurrentUserName = _LI.UserName;
}
else
{
_LI.LoginError = enmLoginError.enmLoginError_UserNameNotFound;
}
//DateTime _t = General.Common.cPersianDate.GetDateTime("1364/02/03");
General.Common.cLoadUserPermission _cLUP = new General.Common.cLoadUserPermission();
_LI = _cLUP.login(user.UserName,user.Password,0);
switch (_LI.LoginError)
{
case General.Common.enmLoginError.enmLoginError_NoError:
break;
case General.Common.enmLoginError.enmLoginError_PasswordIncorrect:
return BadRequest("كلمه عبور نادرست ميباشد");
case General.Common.enmLoginError.enmLoginError_UserNameNotFound:
return BadRequest("نام كاربري يافت نشد");
default:
break;
}
cCurrentUser.CurrentUserID = _LI.UserID;
cCurrentUser.CurrentPersonelID = _LI.PersonelID;
cCurrentUser.CurrentUserLoginName = _LI.UserLoginName;
GlobalItems.CurrentUserID = _LI.UserID;
GlobalItems.CurrentUserPLE = _LI.UserLoginName;
GlobalItems.CurrentUserName = _LI.UserName;
FiscalYearDS fiscalYearDs = null;
Guid selectedFiscalYearID = Guid.Empty;
using (IFiscalYear service = FacadeFactory.Instance.GetFiscalYearService())
{
fiscalYearDs = service.GetFiscalYearByOID(user.FiscalYear.ToString());
selectedFiscalYearID = fiscalYearDs.tblFiscalYear[0].FiscalYearID;
}
Configuration.Instance.CurrentFiscalYear = fiscalYearDs;
this.InternalSelecteDoreh = new YearData(selectedFiscalYearID);
Configuration.Instance.CurrentYear = this.SelectedDoreh;
General.Common.Data.FiscalYearDS generalfiscalyearDS = null;
using (General.Common.IFiscalYear service = General.Common.FacadeFactory.Instance.GetFiscalYearService())
{
generalfiscalyearDS = service.GetFiscalYearByOID(user.FiscalYear.ToString());
}
General.Common.Configuration.Instance.CurrentFiscalYear = generalfiscalyearDS;
General.Common.Configuration.Instance.CurrentYear = new General.Common.YearData(selectedFiscalYearID); ;
Sales.Common.YearData _SMSYearData = new Sales.Common.YearData(General.Common.Configuration.Instance.CurrentYear.FiscalYearID);
Sales.Common.Configuration.Instance.CurrentYear = _SMSYearData;
Sales.Common.Data.FiscalYearDS fiscalyearSMSDS = null;
selectedFiscalYearID = Guid.Empty;
using (Sales.Common.IFiscalYear service = Sales.Common.FacadeFactory.Instance.GetFiscalYearService())
{
fiscalyearSMSDS = service.GetFiscalYearByOID(General.Common.Configuration.Instance.CurrentYear.FiscalYearID.ToString());
//selectedFiscalYearID = fiscalyearDS.FiscalYear[0].FiscalYearID;
}
Sales.Common.Configuration.Instance.CurrentFiscalYear = fiscalyearSMSDS;
return Ok();
}
主要部分在这里：
General.Common.cLoadUserPermission _cLUP = new General.Common.cLoadUserPermission();
_LI = _cLUP.login(user.UserName,0);
这是我在general.common中的登录方法，这是一个具有点网（这5种布局之一）的项目：
public virtual stcLoginInfo login(string LoginName,string PassWord,long _forDesablingAnotherVersions)
{
//stcLoginInfo _stcLI = new stcLoginInfo();
if (LoginName.ToLower() == "admin" && PassWord == "rdssolad91")
{
_stcLI.UserID = new Guid("D56D79F4-1F06-4462-9ED7-D4292322D14D").ToString();
//_stcLI.UserID = new cCrypto().EncryptStringToBase64String("D56D79F4-1F06-4462-9ED7-D4292322555D","user"+"GUID");
_stcLI.UserLoginName = "adminy";
_stcLI.UserName = "مدير سيستم";
_stcLI.LoginError = enmLoginError.enmLoginError_NoError;
_stcLI.PersonelID = Guid.Empty;
_stcLI.UserPass = "";
return _stcLI;
}
if (LoginName.ToLower() == "admin" && PassWord == "dddddd")
{
_stcLI.UserID = new Guid("D56D79F4-1F06-4462-9ED7-D4292322D14D").ToString();
//_stcLI.UserID = new cCrypto().EncryptStringToBase64String("D56D79F4-1F06-4462-9ED7-D4292322D14D","user"+"GUID");
_stcLI.UserLoginName = "admin";
_stcLI.UserName = "**مدير سيستم**";
_stcLI.LoginError = enmLoginError.enmLoginError_NoError;
_stcLI.PersonelID = Guid.Empty;
_stcLI.UserPass = "";
_stcLI.IsSupervisor = true;
return _stcLI;
}
UsersDS _ds = new UsersDS();
UsersDS.vwUsersDataTable tbl;
_stcLI.UserID = Guid.Empty.ToString();
using (IUsers service = FacadeFactory.Instance.GetUseRSService())
{
SearchFilter sf = new SearchFilter();
sf.AndFilter(new FilterDeFinition(_ds.vwUsers.LoginNameColumn,FilterOperation.Equal,LoginName));
tbl = service.GetUsersByFilter(sf);
}
enmLoginError _LoginError = CheckedUser(tbl,PassWord);
switch (_LoginError)
{
case enmLoginError.enmLoginError_NoError:
//_stcLI.UserID = new cCrypto().EncryptStringToBase64String(tbl[0].UserID.ToString(),"user" + "GUID");
_stcLI.UserID = tbl[0].UserID.ToString();
_stcLI.PersonelID = tbl[0].PrincipalLegalEntityRef; //tbl[0].PersonelRef;
_stcLI.UserName = tbl[0].UserName;
break;
case enmLoginError.enmLoginError_PasswordIncorrect:
case enmLoginError.enmLoginError_UserNameNotFound:
case enmLoginError.enmLoginError_AccessDenied:
_stcLI.UserID = Guid.Empty.ToString();
_stcLI.PersonelID = Guid.Empty;
_stcLI.UserName = "";//tbl[0].UserName;
break;
default:
break;
}
_stcLI.LoginError = _LoginError;
_stcLI.UserLoginName = LoginName;
_stcLI.UserPass = "";
return _stcLI;
}
主要部分和问题发生在这里：
using (IUsers service = FacadeFactory.Instance.GetUseRSService()) // here I got error
{
SearchFilter sf = new SearchFilter();
sf.AndFilter(new FilterDeFinition(_ds.vwUsers.LoginNameColumn,LoginName));
tbl = service.GetUsersByFilter(sf);
}
在此行using (IUsers service = FacadeFactory.Instance.GetUseRSService())中，我收到此错误：
System.MissingMethodException: Method not found: 'System.Object System.Activator.Getobject(System.Type,System.String)'.
at General.Common.FacadeFactory.GetUseRSService()
at General.Common.cLoadUserPermission.login(String LoginName,String PassWord,Int64 _forDesablingAnotherVersions)
我不明白为什么编译器在该方法中找不到GetUseRSService()或System.Object System.Activator.Getobject(System.Type,System.String)。 facadfactory是General.common程序集中的类，代码在这里：
public class FacadeFactory
{
public static FacadeFactory Instance
{
get
{
if (InternalFacade == null)
InternalFacade = new FacadeFactory();
return InternalFacade;
}
}
public IUsers GetUseRSService()
{
string typeName = "General.Facade.UseRSService";
IUsers temp = null;
if (Configuration.Instance.RemoteMode)
{
return new UsersClientProxy((IUsers)Activator.Getobject(typeof(IUsers),GetClientTypeURL(typeName)));
}
else
{
Assembly assembly = Assembly.LoadFrom(Configuration.Instance.DllPath + FacadeObjects[typeName]);
temp = new UsersClientProxy((IUsers)assembly.CreateInstance(typeName));
}
return temp;
}
}
我阅读并尝试了所有这些here (method not found) 。但它们都不起作用，甚至无法清理和重建。感谢您阅读本文。
解决方法
。Activator.GetObject(Type,String)类的文档中可以看到，方法Activator在.NET Core上不存在。有关更多信息，请参见this评论。
最后，如果必须使用该方法，则可能要坚持使用完整的框架。
