I was given this solution to a problem I had, since I didn\'t know how to integrate MS Word with C#: http://www.dotnetperls.com/word
I looked into this solution, and
Check if the library (Microsoft.Office.Interop.word) is present in the assembly folder of windows (C:\Windows\assembly) else you can install it from http://www.microsoft.com/en-us/download/details.aspx?id=3508
Now you just need locate it in your visual studio.
Right click on the consoleApplication(or name of you application) in SolutionExplorer window and
Go to Add -> References-> Browse and find C:\Windows\assembly\GAC_MSIL\Microsoft.Office.Interop.word or similar directory. press ok and your can now use the library in your application.
You need Microsoft Word xx Object Library
.
You may also use NuGet Package Manager in order to install the reference. Go to Project -> Manage NuGet Packages... Search for "Interop.Word" and install that package.
Good thing about it is that you don't need to think about where the dll is located. When another person will check out the solution, NuGet will get all needed packages onto their machine.
you might need to install the assemblies separately,if you did not choose to install them during your office installation.
MSDN:
You must install the Microsoft Office primary interop assemblies (PIAs) in the global assembly cache of your development computer before you can perform certain development tasks. Typically, the PIAs are installed automatically when you install Office on the development computer. However, in some cases you might need to install the PIAs separately.
