Question

希望有人可以帮助我。我有一个方法（user_login），而不是提示用户登录，然后生成并返回发票和令牌。

问题是，如果用户已经登录（我将其保留在List中），则不得调用方法svr.logonex。我应该从前一个实例中检索值。我想我必须保存svr变量，但我不知道该怎么做。任何帮助将不胜感激。感谢

以下是代码：

public EPS30Ora.LogonResult User_Login(input_params inputparams)
        {
          EPS30Ora.EPS30Svr svr = new EPS30Ora.EPS30Svr();
         if (Users.Exists(Username => Username.Username.Equals(inputparams.Username)))
            {
                List<input_params> selected = Users.Where(Username => Username.Username.Equals(inputparams.Username)).ToList();
                svr.PrepareByMoney(selected[0].ck, 1, inputparams.meter_number, 10, 0, ref cal);
            }
            else 
            {

                Log_Res = svr.LogOnEx("EDEESTE", inputparams.VSID, inputparams.Username, inputparams.Password, "EPS30Ora", ref inputparams.ck);

                if (Log_Res == EPS30Ora.LogonResult.psOK)
                {
                    try
                    {
                        Users.Add(inputparams);
                        object tr_bl = svr.GetInvoiceData(inputparams.ck, svr.Confirm(inputparams.ck));
                    }
                    catch (System.Runtime.InteropServices.COMException ex)
                    {
                        Trace.WriteLine("Se ha producido una excepción: " + ex);

                    }
              }


            }

            return Log_Res;
        }

Answer 1

听起来你需要拉这个：

EPS30Ora.EPS30Svr svr = new EPS30Ora.EPS30Svr（）;

退出Login方法，并将其移动到调用此方法的任何内容中，以便将此对象保持在更长的范围内。否则，从方法返回时会破坏对象。

然后，您可以将其作为参数传递给此方法，例如：

// Start user process

EPS30Ora.EPS30Svr svr = new EPS30Ora.EPS30Svr();

if (Users.Exists(Username => Username.Username.Equals(inputparams.Username))) {
 // do something
}
else {

}

...

public LogOn(EPS30Ora.EPS30Svr svr, input_params inputparams)
{
Log_Res = svr.LogOnEx("EDEESTE", inputparams.VSID, inputparams.Username, inputparams.Password, "EPS30Ora", ref inputparams.ck);
}
