Overview:

In my case I have InfoPath form to capture   First Name, Last Name, and Email of customers. I need to access these values programmatically.

Understanding:

Fields declared in custom InfoPath form are stored as ‘my:{fieldname}’ format .

Field name   Display name XML representation
txtFirstName First Name my:txtFirstName
txtLastName Last Name my:txtLastName
txtEmailAddress Email Address my:txtEmailAddress

Solution:

There are many ways to access InfoPath form.  In this solution we are using following steps to retrieve InfoPath form data.

  • Identify field names and their XML representation
  • Read InfoPath form  item from InfoPath document Library
  • Load  attached InfoPath form’s XML representation  to XmlTextReader
  • Read each node using XmlTextReader and extract user input  based on our requirement

Code:

Source Code : ReadFromInfoPathForm
