很好的C#操作word例子

Word.ApplicationClass MyWord=new Word.ApplicationClass();
    Word.Document MyDoc;    
    Object Nothing=System.Reflection.Missing.Value;
    MyDoc=MyWord.Documents.Add(ref Nothing,ref Nothing,ref Nothing,ref Nothing);
    MyDoc.Paragraphs.Last.Range.Text=this.richTextBox1.Text;
    object MyFileName=FileName;
    //将WordDoc文档对象的内容保存为DOC文档
    MyDoc.SaveAs(ref MyFileName,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing);
    //关闭WordDoc文档对象
    MyDoc.Close(ref Nothing, ref Nothing, ref Nothing);
    //关闭WordApp组件对象
    MyWord.Quit(ref Nothing, ref Nothing, ref Nothing);  
    MessageBox.Show("WORD文件保存成功","信息提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
