How to get Assembly version string (C#)?

First of all: in this post I'm talking about Assembly version, not its file version which is different thing:

Here you go:

/// Returns version of the current Assembly

/// </summary>

/// <returns>Version string in format x.x.x.x</returns>

private string GetAppVersion()

{

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

}
