Ben WebSupergoo gelen ABCpdf kullanarak, aşağıdaki kodu kullanılmış, ama çoğu kütüphaneler karşılaştırılabilir sınıfları var düşünün:
protected void Button1_Click(object sender, EventArgs e)
{
Doc thedoc = new Doc();
string saveFile = "~/docs/f1_filled.pdf";
System.Text.StringBuilder sb = new System.Text.StringBuilder();
thedoc.Read(Server.MapPath("~/docs/F1_2010.pdf"));
foreach (Field fld in thedoc.Form.Fields)
{
if (!(fld.Page == null))
{
sb.AppendFormat("Field: {0}, Type: {1},page: {4},x: {2},y: {3}\n", fld.Name, fld.FieldType.ToString(), fld.Rect.Left, fld.Rect.Top, fld.Page.PageNumber);
}
else
{
sb.AppendFormat("Field: {0}, Type: {1},page: {4},x: {2},y: {3}\n", fld.Name, fld.FieldType.ToString(), fld.Rect.Left, fld.Rect.Top, "None");
}
if (fld.FieldType == FieldType.Text)
{
fld.Value = fld.Name;
}
}
this.TextBox1.Text = sb.ToString();
this.TextBox1.Visible = true;
thedoc.Save(Server.MapPath(saveFile));
Response.Redirect(saveFile);
}
This does 2 things:
1) Populates a textbox with the inventory of all Form Fields, showing their name, fieldtype, and their page number and position on the page (0,0 is lower left, by the way).
2) Populates all the textfields with their field name in an output file - print the output file, and all of your text fields will be labelled.
