如何使用.NET平台阅读智能卡ACS 38。 [英] How do I read Smart Card ACS 38 using .NET platform.

问题描述

'Establish context and obtain hContext handle
       retcode = ModWinsCard.SCardEstablishContext(ModWinsCard.SCARD_SCOPE_USER, 0, 0, hContext)
       If retcode <> ModWinsCard.SCARD_S_SUCCESS Then
           MessageBox.Show(" Could not establish Connection")
           RichTextBoxLogs.Clear()
           RichTextBoxLogs.Text = "Not Initialized"
           Exit Sub
       End If

       retcode = ModWinsCard.SCardListReaderGroups(hContext, sReaderGroup, ReaderGroup)
       If retcode <> ModWinsCard.SCARD_S_SUCCESS Then
           'DisplayOut(GetScardErrMsg(retcode))
           RichTextBoxLogs.Clear()
           RichTextBoxLogs.Text = "List not found"
           Exit Sub
       End If


       'List PCSC card readers installed
       retcode = ModWinsCard.SCardListReaders(hContext, sReaderGroup, sReaderList, ReaderCount)
       If retcode <> ModWinsCard.SCARD_S_SUCCESS Then
           'DisplayOut(GetScardErrMsg(retcode))
           RichTextBoxLogs.Clear()
           RichTextBoxLogs.Text = "Card not installed"
           Exit Sub
       End If

       RichTextBoxLogs.Text = "Hello Connecting"



       ' Connect to the reader using hContext handle and obtain hCard handle
       retcode = ModWinsCard.SCardConnect(hContext, cmbReaderPort.Text, 1, 0 Or 1, hCard, Aprotocol)

       If (retcode <> ModWinsCard.SCARD_S_SUCCESS) Then
           MessageBox.Show("Connection Error")
       Else

           MessageBox.Show("Connection OK")

       End If

我的意思是涉及的步骤如下：创建句柄，开幕式，我开始检测连接到系统的设备。任何帮助都会非常值得赞赏。



提前致谢

I mean what are broad steps involved like : creating Handle , Opening Session, I did start with detecting the device attached to the system. Any help will be highly appreciable.

Thanks in advance
