PDF找到但未能打開iTextSharp

我正在使用iTextSharp和下面的代碼工作到上週，所以我很難過，我懷疑iTextSharp更新。PDF找到但未能打開iTextSharp

PDF文件被發現，但隨後不打開編輯..

錯誤行（底部完整的錯誤）：

If System.IO.File.Exists(sourceFile) Then ' found here 
    reader = New iTextSharp.text.pdf.PdfReader(sourceFile) 'fails here, see error at bottom of query

的資源文件是從同一網站：www.website.com /folder/pdftest.pdf我已經試過當地以及即C：」 ...... pdftest.pdf

所有代碼：

Dim reader As iTextSharp.text.pdf.PdfReader = Nothing 
Dim stamper As iTextSharp.text.pdf.PdfStamper = Nothing 
Dim img As iTextSharp.text.Image = Nothing 
Dim img1 As iTextSharp.text.Image = Nothing

Dim overContent As iTextSharp.text.pdf.PdfContentByte = Nothing 
Dim rect As iTextSharp.text.Rectangle = Nothing 

'Dim X, Y As Single 
Dim pageCount As Integer = 0 


If System.IO.File.Exists(sourceFile) Then 
    reader = New iTextSharp.text.pdf.PdfReader(sourceFile) 
    rect = reader.GetPageSizeWithRotation(1) 
    stamper = New iTextSharp.text.pdf.PdfStamper(reader, New System.IO.FileStream(outputFile, System.IO.FileMode.Create)) 
    pageCount = reader.NumberOfPages() 

    For i As Integer = 1 To pageCount 

     '############# 
     overContent = stamper.GetOverContent(i) ' can be over or under the existing layers 
     watermarkFont = iTextSharp.text.pdf.BaseFont.CreateFont(iTextSharp.text.pdf.BaseFont.HELVETICA, iTextSharp.text.pdf.BaseFont.CP1252, iTextSharp.text.pdf.BaseFont.NOT_EMBEDDED) 
     watermarkFontColor = iTextSharp.text.Basecolor.BLACK 
     overContent.BeginText() ' black set text first 
     overContent.SetFontAndSize(watermarkFont, 22) 
     overContent.SetColorFill(watermarkFontColor)

     overContent.ShowTextAligned(Element.ALIGN_CENTER, "on", 300, 275, 0) 
     overContent.EndText() 

    Next 

    stamper.Close()

也許文件存在，但您沒有權限讀取它。請參閱http://stackoverflow.com/questions/21649197/itextsharp-cant-find-pdf和http://stackoverflow.com/questions/16699386/determine-what-user-account-itextsharp-runs-as和http：/ /stackoverflow.com/questions/1637505/read-pdf-using-itext –

嘗試將該文件移到網站目錄之外的另一個文件夾中，看看是否可以這樣做？ – Codexer

有沒有給定名稱的目錄？一個目錄確實存在，但不能像文件一樣打開閱讀。 – mkl

Dim myBytes = System.IO.File.ReadAllBytes(sourceFile) reader = New iTextSharp.text.pdf.PdfReader(myBytes)來自@ Chris-Haas的答案是沒有改變任何設置。

對於我來說，這比解決DLL和權限問題更加清晰。 – ilasno

檢查是否在Windows中阻止了itextsharp.dll文件。右鍵單擊itextsharp.dll文件並選擇屬性。在常規選項卡的底部可能有一個Unblock按鈕。點擊那個按鈕。

這將解釋爲什麼System.IO可以讀取文件，但iTextSharp不能。
