Question

I want to show my Silverlight 3 application’s version number in the about box, but when I use a traditional .Net call like:

Assembly.GetExecutingAssembly().GetName().Version;

I get a MethodAccessException on the GetName() call. How am I supposed to get the version number of my assembly?

Answer 1

private static Version ParseVersionNumber(Assembly assembly)
{
    AssemblyName assemblyName = new AssemblyName(assembly.FullName);
    return assemblyName.Version;
}

or this:

Assembly assembly = Assembly.GetExecutingAssembly(); 
String version = assembly.FullName.Split(',')[1];
String fullversion = version.Split('=')[1];
