In ASP.NET you use the MapPath method:

var siteRootPath = Server.MapPath("~/");

Yet another possibility is to use the ApplicationPhysicalPath static property:

var path = HostingEnvironment.ApplicationPhysicalPath;

First thing you cannot run your executable from client end. It has to be a server side code which would run on server and for this you can use the similar logic.
