问题描述
大家好，
我目前正在使用ItextSharp来创建PDF文件。我正在制作一个标题以及下表。该表没有任何问题，但是当标题运行时，它会创建4个标题的副本。我一直在尝试并努力解决这个问题，但到目前为止，我在多个小时后都没有运气。
Hello all,
I am currently using ItextSharp to create a PDF file. I am working on generating a header along with a table below. The table works without any problems but when the header runs it creates a duplicate of 4 headers. I have been experimenting and working on solving this problem but so far I have had no luck after multiple hours.
class PrintForAccess {
Document printAccess2CareDoc;
const int LINES_PER_ACCESS2CARE_DOC = 5;
int pageCount = 0;
PdfWriter writer;

{

writer = PdfWriter.GetInstance(printAccess2CareDoc, outputstream);
PdfAcroForm acroForm = writer.AcroForm;
printAccess2CareDoc.Open();
PdfPTable table = printAccess2CareInitTable(defaultFont);
PdfPTable headTable = printHeadTableAccess2Care(headerFont);
int detailLine = 0;
driver previousDriver = null;
bool firstRec = true;
foreach(ride record in records)
{
if(groupByDriver && record.driver != previousDriver || firstRec)
{
previousDriver = record.driver;
detailLine = 0;
printAccess2CareNewPage(ref table, ref headTable, defaultFont, headerFont, firstRec);
}
printAccess2CareHeader(headTable, record, ridedate);
printAccess2CareDetail(table, defaultFont, writer, record, ridedate);
if((++detailLine) == LINES_PER_ACCESS2CARE_DOC)
{
detailLine = 0;
printAccess2CareNewPage(ref table, ref headTable, defaultFont, headerFont, false);
}
firstRec = false;
}

推荐答案
这是我的问题的答案
我终于解决了!!
Here is the answer to my question
I finally solved it!!
foreach(ride record in records)
{
if(groupByDriver && record.driver != previousDriver || firstRec)
{
if(!firstRec)
{
printAccessFivelengths(ref table, defaultFont, detailLine, headTable, headerFont);
}
previousDriver = record.driver;
if (record.driver != null && (driverid != 0 || groupByDriver))
{
//pageHeaderWithDriver.Add(new Phrase(titlec1 + record.driver.person.fullname, headerFont));
c4r2head = new PdfPCell(new Phrase(record.driver.person.fullname, headerFont));
headerTable.AddCell(c4r2head);
}
detailLine = 0;
printAccessHeader(headTable, record, ridedate, username);
printAccessNewPage(ref table, ref headTable, defaultFont, headerFont, firstRec);
table = printAccessInitTable(defaultFont);
headTable = printAccessHeaderInit(headerFont);
}
printAccessDetail(table, defaultFont, writer, record, ridedate);
if((++detailLine) == LINES_PER_ACCESS_DOC)
{
detailLine = 0;
//print new page
printAccessHeader(headTable, record, ridedate, username);
printAccessNewPage(ref table, ref headTable, defaultFont, headerFont, false);
}
firstRec = false;
}
