我使用Itextsharp将数据合并为1行并将其放入excel，因为第二行在下一页中，所以我无法获得我想要的行，因为它只能逐页读取PDF。 代码如下：
if (File.Exists(theFile.FullName))
{
Console.Write(++count + " " + theFile.FullName);
PdfReader pdfReader = new PdfReader(theFile.FullName);
try
{
DataTable finalTbl = GetTable();
for (int page = 1; page <= pdfReader.NumberOfPages; page++)
{
ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy); //Convert to text from PDF
string[] theLines = currentText.Split(Environment.NewLine.ToCharArray());
using (StringReader reader = new StringReader(currentText))
{
string line;
while ((line = reader.ReadLine()) != null)
{
string[] splittedTxt = line.Split(new[] { " " },
StringSplitOptions.RemoveEmptyEntries);
if (splittedTxt.Any())
{
// create a table
}
finalTbl.Rows.Add( //add desired datatable)
}
}
}
}
}
catch
{
throw;
}
finally
{
pdfReader.Close();
}
}
我得到的结果：
17-Oct Electrical Fan with RF895 cable model XO-8745 56148

在创建数据表之前，有什么方法首先读取和合并所有页面吗？
