> When I sign a pdf and got the signed pdf into a file, it runs fine. (

>
> But if I want to keep the signed file in a MemoryStream in place of a
> FileStream, when the signature has been done (st.close()), my
> MemoryStream no longer exists, it has been "disposed" and I get a
>
> System.ObjectDisposedException
>
> Is there an error in the code? or st.close() makes free the stream

> Below the code:
>
> PdfReader reader = new PdfReader("filetosign.pdf");
>
> MemoryStream signedStream = new MemoryStream();
> //xxx FileStream signedStream = new new FileStream("signedFile.pdf",
> FileMode.Create, FileAccess.Write);
>
> //In the next instruction I use a Memory Stream in place of a
> FileStream to get the result
> PdfStamper st = PdfStamper.CreateSignature(reader,
> signedStream, '\0',null);
>
> st.SetEncryption(PdfWriter.STRENGTH128BITS, null,"hello",
> PdfWriter.AllowPrinting);
> PdfSignatureAppearance sap = st.SignatureAppearance;
>
> sap.SetCrypto(this.myCert.Akp, this.myCert.Chain, null,

>
> sap.Reason = "x";
> sap.Contact = "y";
> sap.Location = "z";
>
> st.Close();
>
> //xxx FileStream signedStream = new new FileStream("signedFile.pdf",
> FileMode.Open, FileAccess.Read);
