关于调用类里的函数

Question

我在类里写了一个函数,但是调用的时候却报错,类中不包含该函数的定义
请问怎么回事

Answer 1

你不会把函数定义成Private的吧
你把类贴出来看看

Answer 2

public byte[] GetCardDetails(int Area, string  TimeStart, string TimeEnd)
        {
            byte[] result = null;
            string ReportName = "CardDetails";            Hashtable hsdtCardInfo = new Hashtable();
            hsdtCardInfo.Add("Area", Area);
            hsdtCardInfo.Add("TimeStart", TimeStart);
            hsdtCardInfo.Add("TimeEnd", TimeEnd);            return result = ExcelHelper.GetSANARegInfo(hsdt, ReportName);
        }

Answer 3

调用的代码:
aryResult = new ExcelReports().GetCardDetails(Convert.ToInt32(DDLArea.SelectedValue),CalendarPopup1.SelectedDate.ToString(), CalendarPopup2.SelectedDate.ToString());

Answer 4

一般来说是参数的问题 如果是函数用了private编译器还是会识别的
，应该先检查是否有这个函数 然后再检查访问级别

Answer 5

这是类里的函数：
public byte[] GetCardDetails(int Area, DateTime TimeStart, DateTime TimeEnd)
        {
            byte[] result = null;
            string ReportName = "CardDetails";            Hashtable hsdtCardInfo = new Hashtable();
            hsdtCardInfo.Add("Area", Area);
            hsdtCardInfo.Add("TimeStart", TimeStart);
            hsdtCardInfo.Add("TimeEnd", TimeEnd);            return result = ExcelHelper.GetSANARegInfo(hsdt, ReportName);
        }
在这里调用的函数：
private void CardDetailsDownload()
    {
        byte[] aryResult = null;
        string strFileName = "";
        try
        {
            strFileName = DDLArea.SelectedValue.ToString();            aryResult = new ExcelReports().GetCardDetails(Convert.ToInt32(DDLArea.SelectedValue), CalendarPopup1.SelectedDate, CalendarPopup2.SelectedDate);            Response.AddHeader("Content-Disposition", "attachment; filename=" + strFileName);
            Response.ContentType = "application/octet-stream";
            Response.BinaryWrite(aryResult);
            Response.End();
            new ExcelReports().CloseExcel();        }
        catch (Exception ex)
        {
            //new ReportManager().CloseExcel();
            new ExcelReports().CloseExcel();
            throw ex;
        }
    }问题出在哪里呢

这是类里的函数：
public byte[] GetCardDetails(int Area, DateTime TimeStart, DateTime TimeEnd)
        {
            byte[] result = null;
            string ReportName = "CardDetails";            Hashtable hsdtCardInfo = new Hashtable();
            hsdtCardInfo.Add("Area", Area);
            hsdtCardInfo.Add("TimeStart", TimeStart);
            hsdtCardInfo.Add("TimeEnd", TimeEnd);            return result = ExcelHelper.GetSANARegInfo(hsdt, ReportName);
        }
在这里调用的函数：
private void CardDetailsDownload()
    {
        byte[] aryResult = null;
        string strFileName = "";
        try
        {
            strFileName = DDLArea.SelectedValue.ToString();            aryResult = new ExcelReports().GetCardDetails(Convert.ToInt32(DDLArea.SelectedValue), CalendarPopup1.SelectedDate, CalendarPopup2.SelectedDate);            Response.AddHeader("Content-Disposition", "attachment; filename=" + strFileName);
            Response.ContentType = "application/octet-stream";
            Response.BinaryWrite(aryResult);
            Response.End();
            new ExcelReports().CloseExcel();        }
        catch (Exception ex)
        {
            //new ReportManager().CloseExcel();
            new ExcelReports().CloseExcel();
            throw ex;
        }
    }问题出在哪里呢
