I want to send a binary file to .net c# component in the following xml format
<BinaryFileString fileType='pdf'>
<!--binary file data string here-->
</BinaryFileString>
In the called component I will use the above xml string and convert the binary string received within the BinaryFileString tag, into a file as specified by the filetype='' attribute. The file type could be doc/pdf/xls/rtf
I have the code in the calling application to get out the bytes from the file to be sent. How do I prepare it to be sent with xml tags wrapped around it? I want the application to send out a string to the component and not a byte stream. This is because there is no way I can decipher the file type [pdf/doc/xls] just by looking at the byte stream. Hence the xml string with the filetype attribute. Any ideas on this?
method for extracting Bytes below
FileStream fs = new FileStream(_filePath, FileMode.Open, FileAccess.Read);
using (Stream input = fs)
{
byte[] buffer = new byte[8192];
int bytesRead;
while ((bytesRead = input.Read(buffer, 0, buffer.Length)) > 0)
{}
}
return buffer;
Thanks.
Edit:
Just to clarify why I am using an xml string rather than setting properties on my component. Actually my calling app is trying to simulate how Siebel will call my component.

Im not sure if Siebel can set my components properties as I need it to. So Im working on the angle of it sending the data in xml.

Base64 representation is universaly used to represent binary data.
At the receiving end you can reverse this and get back original file content as mentioned below.
