this never happends on a Windows machine. So i gues this is a problem related to the environment.
the relevant code will be
- Code: Select all
for (int i = 0; i < pdfForm.FieldsWidget.List.Count; i++)
{
PdfField field = pdfForm.FieldsWidget.List[i] as PdfField;
if (field is PdfTextBoxFieldWidget)
{
PdfTextBoxFieldWidget textBox = (PdfTextBoxFieldWidget)field;
if (retVal.FirstOrDefault(x => x.PosX == textBox.Location.X && x.PosY == textBox.Location.Y && x.PageNr == document.Pages.IndexOf(field.Page)) == null)
{
retVal.Add(new FormEntry() { EntryType = FormEntryType.TextField, Name = textBox.Name, Contend = textBox.Text, PosX = textBox.Location.X, PosY = textBox.Location.Y, PageNr = document.Pages.IndexOf(field.Page),PageSize=field.Page.Size });
Debug.WriteLine($"processing TextBox {textBox.Name}");
if (keyValuePairs.ContainsKey(textBox.Name))
{
[color=#FF0000]textBox.Text = keyValuePairs[textBox.Name];[/color]
}
else if (useMaping)
{
if (fieldKeyMapping.ContainsKey(textBox.Name))
{
textBox.Text = keyValuePairs[fieldKeyMapping[textBox.Name]];
}
}
The red maked Line raises the exception. after 5-7 Fields to fill.
Has sombody souch problem ? How can i workaround ?
