Transfer file using Web Services in ASP.NET with C# (Ex:Sending Bank Statement Details)

We can transfer file using webservices, this is very easy. In my example i have taken bank statement pdf file. We have to give Account number, All ready we have PDFs in the particular folder (Ex: D:\AccountPDFFolders\" + AccountNumber + "_Statement.pdf";", Our example will take file from source and transfer through web service. Also, we can return status. like if status=1, file is there if not status =2(file does not exist)... Enjoy...
