Microsoft.Office.Interop.Word.Application w = new  Microsoft.Office.Interop.Word.Application();
    Microsoft.Office.Interop.Word.Document doc;
    int iParaStart = Para.Range.Start;
    Para.Range.Text = "A big Paragraph Comes here …….";
    Para = doc.Paragraphs.Add();
    int iParaEnd = Para.Range.End; 
  // to select the first sentance code tried       
  doc.Range(iRangeStart,iRangeEnd).Sentences.First.Select();
doc.Range(iRangeStart,iRangeEnd).Sentences.First.Shading.BackgroundPatternColor=WdColor.wdColorOrange;
 // to get the characters code tried
 doc.Range(iRangeStart,iRangeStart+20).Select();

It seems like not working How can i do this . I need to select the either first sentence or first 20 characters

If you're using this code in a long running application or working with many files, this link (http://stackoverflow.com/questions/158706/how-to-properly-clean-up-excel-interop-objects/158752#158752) will help with hanging Office processes (Same issues applies to Word as to Excel) — jordanhill123, Apr 05 '13 at 07:31

Try using (i assumed you have properly open application and word document):

// get paragraph range
paragraphs = doc.Paragraphs;
Word.Paragraph paragraph = paragraphs.First;
Word.Range paragraphRange = paragraph.Range;

Selecting first sentence:

Word.Sentences sentences = paragraphRange.Sentences;
Word.Range firstSentence = sentences.First;
firstSentence.Select();

Selecting first 20 characters:

if (paragraphRange.Text.Length > 20)
{
    Word.Range range = paragraph.Range.Duplicate;
    range.SetRange(range.Start, range.Start + 20);
    range.Select();
}

Using the following namespace:

using Microsoft.Office.Interop.Word;

... and given a Document instance:

var wordApplication = new Application();
var myDocument = wordApplication.Documents.Open(@"C:\Users\...\my.docx");

... you can select the first 20 chars of a paragraph like this:

var substring = myDocument.Paragraphs.First.Range.Text.Substring(0, 20);

... and you can select the first line like this:

var firstLine = myDocument.Paragraphs.First.Range.Sentences.First.Text;

Thank you for the Answer and i have got the answer from the previous post and I tried your code also it also works. — Jpaul, Apr 08 '13 at 05:10
