小编Sha*_*Sen的帖子

我在下面有这个代码请帮我在每个页面重复表格标题.我试过在网上提供的选项很少,但它们没有用.我是第一次使用ItextSharp.谢谢

    int columns = gv.Columns.Count;
    int rows = gv.Rows.Count;
    int tableRows = rows + 3;   
    string flName = "";

    if (gv.ID == "gvShares")
    {
        flName = "Share_Statement.pdf";
    }

    if (gv.ID == "gvSavingAccStmt")
    {
        flName = "Main_Saving_Account_Statement.pdf";
    }

    Document Doc = new Document();
    PdfWriter.GetInstance(Doc, Response.OutputStream);
    Doc.Open();

    BaseFont bfTimes = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, false);
    Font times = new Font(bfTimes, 9, Font.NORMAL, Color.BLACK);

    //string imageFilePath = HttpContext.Current.Server.MapPath("/Image/Sacco_Logo.jpg");

    string test = System.Web.HttpContext.Current.Server.MapPath(".");

    string substr = test.Remove(test.Length - 6);

    //string imageFilePath = "\\app\\Image\\Sacco_Logo.jpg";//"\\app\\Image\\Sacco_Logo.jpg";
    iTextSharp.text.Image jpg = …

我正在使用以下代码

IEnumerable<DataRow> query = from c in at.appointmentcalendars.AsEnumerable() 
                             select c;

DataTable dt = query.CopyToDataTable();

但我得到以下错误

无法隐式转换'System.Collections.Generic.IEnumerable<appointmentcalendar>'为 'System.Collections.Generic.IEnumerable<System.Data.DataRow>'.存在显式转换(您是否错过了演员？)
