Hi, .check my code:
using Word=Microsoft.Office.Interop.Word;
object oMissing = System.Reflection.Missing.Value;
object oEndOfDoc = "\\endofdoc";
Word._Application oWord;
Word._Document oDoc;
oWord = new Word.Application();
oWord.Visible = true;
oDoc = oWord.Documents.Add(ref oMissing, ref oMissing,
ref oMissing, ref oMissing);
Word.Paragraph oPara1;
oPara1 = oDoc.Content.Paragraphs.Add(ref oMissing);
oPara1.Range.Text = ;
oPara1.Range.Font.Bold = 1;
oPara1.Format.SpaceAfter = 24;
oPara1.Range.InsertParagraphAfter();
