How to programmatically create a Microsoft Word document in csharp

This code shows how to simply create a doc using csharp and Microsoft Office Word library.
1) You need to add a reference to Microsoft.Office.Interop library in your project solution.
2) Add the following line to the end of the list of using directives:
    using Word = Microsoft.Office.Interop.Word;
    using System.Reflection;
3) Now you are ready to create a button and link to it a method to create a doc.
4) Once you click the button, a new Word doc will be created, containing some header sections, paragraphs, tables and chart as well.

This code has been developed and tested for Office 2013 [ver 15].
