So i receive a xml from a web service.  The web service documentation claims that

( The response element returns the binary string that contains the pdf Summary Report image. You must have a method for converting the binary string to human-readable PDF file.)

The binary string that is returned starts like this
( <Image pdf=\"JVBERi0xLjMKJcfsj6IKNSAwIG9iago8PC9MZW5ndGggNiAwIFIvRmlsdGVyIC9GbGF0 ............ ) (attached the full xml )

I am wondering what is the best way to create this pdf file. We also use a tool (PDF4NET) that can accept streams to generate the pdf files.. But not sure the following methods to play with the returned xml..

Thank you

The data is base64 encoded. You should make a string of it and pass it thrue Convert.FromBase64String. (see that " is NOT part of the data at start and end!)
See my sample and result file. The actual data is replaced by ... to keep it smaller..
The resulting file is attached.
string pdf = "JVBE...Rgo=";
byte[] outArray = new byte[60000];
outArray = Convert.FromBase64String(pdf);
System.IO.FileStream sw;
sw = new System.IO.FileStream (@"c:\temp\een.pdf",System.IO.FileMode.CreateNew);
 
for (int i = 0; i < outArray.Length; i++)
   sw.WriteByte(outArray[i]);
sw.Close();
