Decoding the encoded string is not getting the special characters correctly

Hi,

I am using the below code to encode the content of *.ser file

foreach(string file inDirectory.EnumerateFiles("","*.SER")){byte[] content =File.ReadAllBytes( file );
				xmlWriter.WriteStartElement("SerializedFile");
				xmlWriter.WriteElementString("FileName",Path.GetFileName(file));
				xmlWriter.WriteElementString("Content",System.Convert.ToBase64String( content ));
				xmlWriter.WriteEndElement();}

Now i have to decode the encoded content and create *.ser file, i tried with below code but the size of original *.ser file and generated *.ser file after i decode differs and if i check the content i can see some difference with the special characters.

encodedContent = xmlnode[i].ChildNodes.Item(1).InnerText;
                byte[] data = Convert.FromBase64String(encodedContent);
                string decodedContent = Encoding.UTF8.GetString(data);

Please help me out to solve this issue. Thanks in advance.

Regards,

Chetan.
