You can get assembly info from different properties AssemblyVersion, AssemblyFileVersion and AssemblyDescription.

                /// 

                /// This class provide inforamtion about product version.
                /// 
                public class ProductVersion
                {
                    private readonly FileVersionInfo fileVersionInfo;

                    private readonly AssemblyName assemblyName;


                    private ProductVersion(Type type)
                    {
                        // it done this way to prevent situation 
                        // when site has limited permissions to work with assemblies.
                        var assembly = Assembly.GetAssembly(type);
                        fileVersionInfo = FileVersionInfo.GetVersionInfo(assembly.Location);
                        assemblyName = new AssemblyName(assembly.FullName);
                    }

                    public string AssemblyFileVersion
                    {
                        get
                        {
                            return fileVersionInfo.FileVersion;
                        }
                    }

                    public string AssemblyVersion
                    {
                        get
                        {
                            return assemblyName.Version.ToString();
                        }
                    }



                }
