How to get the current product version in C#?

Question

How can I programmatically get the current product version in C#?

My code:

VersionNumber = System.Reflection.Assembly.GetExecutingAssembly().GetName         


        

Answer 1

System.Reflection.Assembly.GetEntryAssembly().GetName().Version

Answer 2

Try this:

var thisApp = Assembly.GetExecutingAssembly();
AssemblyName name = new AssemblyName(thisApp.FullName);
VersionNumber = "v. " + name.Version;

Also, see this Microsoft Doc on the AssemblyName.Version property.

Answer 3

Another approach to getting the product version (which is specified using the AssemblyInformationalVersionAttribute) is

private static string AssemblyProductVersion
{
    get
    {
        object[] attributes = Assembly.GetExecutingAssembly()
            .GetCustomAttributes(typeof(AssemblyInformationalVersionAttribute), false);
        return attributes.Length == 0 ?
            "" :
            ((AssemblyInformationalVersionAttribute)attributes[0]).InformationalVersion;
    }
}
