How to display/manipulate program version number

[cmdematos]

How do I display and manipulate a c# program version number? I think I have the display part, but how do I set the version number from version 1 to version 2?

I'm not sure you can programmatically retrive or modify the version number. There is an Assembly class in the System.Reflection namespace which allows you to access the current asembly. You can load in an assembly from within a class using the static GetAssembly method like this

Type type = this.GetType();
Assembly assembly = Assembly.GetAssembly(type);

However, I don't think it has a version number property :-( though you can modify the version number of the assembly declaritively from within the Assembly.info file in your project root before compilation.

You can control the version of an Assembly (.EXE or .DLL) using [assembly: AssemblyVersion("x.x.x.x")]
that you find in the AssemblyInfo.cs file.
//
// Version information for an assembly consists of the following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
At run time, you can only retrieve that version for the executing assembly like here:

string vs = Application.ProductVersion;
or using  FileVersionInfo or System.Version class
[code]
 FileVersionInfo fvi = FileVersionInfo.GetVersionInfo("my.dll");
 Console.WriteLine("File: " + fvi.FileDescription + '\n' +"Version: " + fvi.FileVersion;

You can control the version from the config file by adding something like that:
<version>
<add key="title" value="MyApp [BETA]"/>
<add key="release" value="0.2.3"/>
</version>
The version could be controlled at assembly level, class level, method level by impleneting an Attribute class, let say AttributeVersion, derived from Attribute class.
Using System.Version class and this custom class you can manage the vesrions over your projects/applications.

You can also access it for the current assembly like this:

Assembly myAssembly = Assembly.GetExecutingAssembly();
AssemblyName myAssemblyName = myAssembly.GetName();
Version myVersion = myAssemblyName.Version();
Console.WriteLine("{0}.{1}.{2}.{3}", myVersion.Major.ToString(), myVersion.Minor.ToString(), myVersion.Build.ToString(), myVersion.Revision.ToString());
