Recently I want to develop a .NET application related to Word. Most of my friends recommend Spire.word for me. But I am not quite sure about it. Then I searched in Google, This spire.doc for .NET is truly in the front . That is a brief introduction on its offical site :Spire.Doc is an MS Word component which enables user to perform a wide range of Word document processing tasks directly, such as generate, read, write and modify Word document for .NET and Silverlight. It supports C#, VB.NET, ASP.NET, ASP.NET MVC and Silverlight.
As a professional and powerful Word component, Spire.Doc doesn't need Microsoft Office Word Automation but also allows user to directly operate Word document, format and style and insert content to Word document. Spire.Doc which with high quality, powerful functions and cheap price supports Word 97, Word 2003, Word 2007 and Word 2010.
and it charge $399, how do you think about it? (not long in this field, not sure about the price) the following is its site
