I’m been working on a project where I need to extract attachments from an InfoPath form. There are some good resources for parsing InfoPath forms (wat net XML-lêers, So dit is eintlik baie maklik).

Terwyl ek die opbou van die projek, I started by downloading an InfoPath form and saving it to my local hard drive. My c# code was reading directly from that instance. Egter, the InfoPath forms are really living inside a SharePoint forms library. I did a little half hearted searching to find out how to read it directly from the library and almost gave up, in which case I would have saved the form to a local temp directory and read it from there. Egter, there’s no need to go through those hoops as you can read it directly from the library. This little snippet shows how:

/// Klas definisie dinge hier, insluitende:

private SPFile mySharePointFile; /* Deel van 'n SPList */

// Meer kode gaan hier en binne 'n metode van die klas het ons 'n:
XmlTextReader textReader;

textReader = nuwe XmlTextReader(mySharePointFile.OpenBinaryStream());

textReader.WhitespaceHandling = WhitespaceHandling.Geen;

textReader.Read();

// Indien die knoop het waarde

terwyl (textReader.Read())
{

Hulle het die sleutel bietjie bogenoemde is dat ons kan die Path direk lees via die OpenBinaryStream() method call on the SPFile as a parameter to the constructor on XmlTextReader. It works great.
