How to get current assembly version and build time?
private static string GetAssemblyVersionBuildDate()
{
string filePath = System.Reflection.Assembly.GetCallingAssembly().Location;
const int c_PeHeaderOffset = 60;
const int c_LinkerTimestampOffset = 8;
byte[] b = new byte[2048];
System.IO.Stream s = null;
try
{
s = new System.IO.FileStream(filePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
s.Read(b, 0, 2048);
}
finally
{
if (s != null)
{
s.Close();
}
}
int i = System.BitConverter.ToInt32(b, c_PeHeaderOffset);
int secondsSince1970 = System.BitConverter.ToInt32(b, i + c_LinkerTimestampOffset);
DateTime dt = new DateTime(1970, 1, 1, 0, 0, 0);
dt = dt.AddSeconds(secondsSince1970);
dt = dt.AddHours(TimeZone.CurrentTimeZone.GetUtcOffset(dt).Hours);
return "v"+ System.Reflection.Assembly.GetCallingAssembly().GetName().Version.ToString() + " "+ dt.ToString();
}
