Question

in my application, when user click on particular link button, MS word has to open how can i write the code for this. Thank you

There is no way to guarantee that a particular application will be opened when a user clicks a link / button on a web page. The application that is opened is determined by the user’s browser and operating system settings.

As a developer you can specify the MIME type of the file that you are returning. By doing so you are telling the user’s browser what file type is contained in the response. W3Schools provides a pretty good MIME type by content type list and FILExt also provides the MIME type for the files it lists.

Assuming you specify the appropriate MIME content-type you can be sure the user’s browser and operating system will open the file in the “appropriate” application according to their settings. Since you want to open a Word Document file the appropriate MIME content-type will be one of the following:

 Extension Type/sub-type
 docx      application/vnd.openxmlformats-officedocument.wordprocessingml.document
 doc       application/msword
 

How and where you specify the content-type largely depends on the ASP.NET application type you are working with. If you are writing a ASP.NET Webforms application you’d change the MIME type of the Response object in the Page_Load method. In an ASP.NET MVC application you’d do so in a controller action. In either case the specific line of code is the same.

Response.ContentType = "application/msword";
