下面是VB代码片段：
... Dim log() As PosLogInfo  ... Case 2 '读所有记录             GetDeviceVersion = ""             strFuncData = objComm.SysGetDeviceVersion             strCmd = objComm.CreateBstrCommand(MacID, MacType, strFuncData)       '生成指令帧             If Not ExecCommandIsSuccess(cmdXF(Index).Caption) Then Exit Sub             GetDeviceVersion = objComm.GetMacModelVersion(strFrame)             strFuncData = objComm.XFAllLogCount             strCmd = objComm.CreateBstrCommand(MacID, MacType, strFuncData)       '生成指令帧             txtSend.Text = txtSend.Text & strCmd & vbCrLf             If Not ExecCommandIsSuccess(cmdXF(Index).Caption) Then Exit Sub                          objComm.GetRecordCount strFrame, GetDeviceVersion, RecordSector, RecordCount             For i = 1 To RecordSector                 DoEvents                 strFuncData = objComm.XFAllLogData & objComm.NumToHexStr(i, 2)                 strCmd = objComm.CreateBstrCommand(MacID, MacType, strFuncData)       '生成指令帧                 txtSend.Text = txtSend.Text & strCmd & vbCrLf                 If Not ExecCommandIsSuccess(cmdXF(Index).Caption, False) Then Exit For                 If MacType = 6 Then                     If objComm.GetXFLogOrder(strFrame, log) Then                         For j = 0 To UBound(log)                             txtReturn.Text = txtReturn.Text & log(j).SFType & " " & log(j).SFMealTypeID & " " & _                                 log(j).CardNo & " " & log(j).SFDate & " " & log(j).SFAmount & " " & _                                 log(j).CardBalance & " " & log(j).CardUseTimes & vbCrLf                         Next                     Else                         txtReturn.Text = txtReturn.Text & strFrame & vbCrLf                     End If                 Else                     If objComm.GetXFLog(strFrame, log()) Then                                              For j = 0 To UBound(log)                             txtReturn.Text = txtReturn.Text & log(j).SFType & " " & log(j).SFMealTypeID & " " & _                                 log(j).CardNo & " " & log(j).SFDate & " " & log(j).SFAmount & " " & _                                 log(j).CardBalance & " " & log(j).CardUseTimes & vbCrLf                         Next                     Else                         txtReturn.Text = txtReturn.Text & strFrame & vbCrLf                     End If                 End If             Next



上面这个代码是VB的 都是调用DLL 我现在在C#的写法遇到两个问题
1.PosLogInfo这个是结构体，C#的定义？
2.objComm.GetXFLog(strFrame, log())这个语句里面参数log()在C#中应该什么写？


下面是我乱写了一下：
...
ECardDeviceAPI.PosLogInfo[] log= new ECardDeviceAPI.PosLogInfo[20];
...
objComm.GetXFLog("1111111111",ref  log);
结果不通
