I have a ASP.Net (.net 3.5/c#) and I want to display a version number / build number and date. What is the best way in controling this and is it possible to auto incriment the numbers on build?

What is the standard for version numbers & build number?

Im using VS 2008 how would I get the data and assign to a string value so I can show in the footer of the webpage?

If you're using a Web Application Project - you could do it like this...

Assembly web = Assembly.Load("App_Code");
AssemblyName webName = web.GetName();

string myVersion = webName.Version.ToString();

If you're using a Web Site project - nearly the same...

Assembly web = Assembly.GetExecutingAssembly();
AssemblyName webName = web.GetName();

string myVersion = webName.Version.ToString();

    I'm trying to do this in a razor view (I know i shouldn't but its a shared layout) and it can't see the Assembly... – Worthy7 Sep 17 '16 at 06:42
  • @Worthy7, for a Razor view, you can set the Version in an Application variable in Application_Start() event (global.asax) like this: Application["Version"] = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();. Then retrieve it in the Razor view like this:

    version @Context.Application["Version"].ToString()

You can set the first two parts of the version number, and leave a wildcard for the compiler to autocomplete the last two parts, by editing the GlobalAssemblyInfo.cs like so:

[assembly:AssemblyFileVersion("1.0.*")]

It autocompletes the last two parts with a number of days since 1st Jan 2000, and the number of seconds since midnight. This may help with the second part of your query to display the date/time the version was built.

    cool! then you can get the version: System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString() – Saber Nov 01 '11 at 16:05
  • the last part of the auto-completed version (the default revision number) is the number of seconds since midnight local time (without taking into account time zone adjustments for daylight saving time), divided by 2.
