Extract lines between two keywords in Word Document

Question

Need to search for two keywords in Word document

 

E.g..

 

Keyword1

Keyword2

 

Lines between both the keywords then needs to be returned.

 

Trying this but i couldn't get this to work even for single keyword search

 

 using word = Microsoft.Office.Interop.Word;

object fileName = "D:\\Files\\Scan.doc"; //The filepath goes here
string textToFind = "Keyword1"; //The text to find goes here
Word.Application word = new Word.Application();
Word.Document doc = new Word.Document();
object missing = System.Type.Missing;
try
{
doc = word.Documents.Open(ref fileName, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing,
ref missing, ref missing);
doc.Activate();
foreach (Word.Range docRange in doc.Words)
{
if (docRange.Text.Trim().Equals(textToFind,
StringComparison.CurrentCultureIgnoreCase))
{
Response.Write(docRange.Text);
}
}
}
catch (Exception ex)
{
Response.Write("Error : " + ex.Message);
}
