方法 1:
using Bytescout.PDFExtractor;
try
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
FileName = openFileDialog1.FileName;
string FName = FileName;
int a = FileName.LastIndexOf('\\');
txtFileName.Text = FileName.Substring(a + 1);
axAcroPDF1.LoadFile(FileName);
FileInfo fi = new FileInfo(FileName);
string PDFFileName = fi.Name.ToString();
double filesize = (fi.Length / 1024F / 1024F);
string size = filesize.ToString("0.00 MB");
string CreationDate = fi.CreationTime.ToString();
string LastAccessDate = fi.LastAccessTime.ToString();
string ModifiedDate = fi.LastWriteTime.ToString();
lblVersion.Text = "File Name : " + PDFFileName + "\nSize : " + size + "\nCreation Date : " + CreationDate + "\nModified Date : " + ModifiedDate;
TextExtractor extractor = new TextExtractor();
extractor.RegistrationName = "Demo";
extractor.RegistrationKey = "Demo";
extractor.LoadDocumentFromFile(FileName);
int pageCount = extractor.GetPageCount();
RectangleF location;
for (int s = 0; s <= Keywords.Length ‑ 1; s++)
{
if (Keywords[s] != "")
{
TreeNode tNode = new TreeNode();
tNode = treeView1.Nodes.Add(Keywords[s]);
for (int i = 0; i < pageCount; i++)
{
if (extractor.Find(i, Keywords[s], false, out location))
{
do
{
int j = i;
tNode.Nodes.Add((j+1).ToString() + " " + location.ToString());
float X = location.X;
float Y = location.Y;
float Width = location.Width;
float Height = location.Height;
float Left = location.Left;
float Right = location.Right;
float Top = location.Top;
float Bottom = location.Bottom;
//axAcroPDF1.setCurrentHighlight(Convert.ToInt32(X), Convert.ToInt32(Y), Convert.ToInt32(Width), Convert.ToInt32(Height));
}
while (extractor.FindNext(out location));
}
}
}
else
{
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString(), "Exception", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
