How Do I Read Content From A Ms Word Text Box

//after activating the document

foreach(Microsoft.Office.Interop.Word.Range newRange in doc.StoryRanges)
{
    //Pick the object you want to process
    nrwRange.Select();
    //Select the text in the Text Box in Word document.
    string textInTextBoxFromMSWordDocument = newRange.Text;
    //pardon the weird variable name. Just trying to be brief and descriptive as possible.
