__DATE__ equivalent

Question

I'm new to C# coming from a C background. I would simply like access to the build date of my application. In C, I could do this using the __DATE__ macro. How would I do this in Visual C#?

TIA

Answer 1

Use DateTime structure in C#!

See MSDN for help and more details! its really very simple to use!

Best Regards,

Answer 2

I guess there is no way to do that. C# does not allow defines with values. It allows only "is defined" or "is not defined".

hi,

i don't know c and i don't know if you can do that useing System.Refliction or not but you can get the creationdate from System.IO

class Program { static void Main(string[] args) { string strpath = System.Reflection.Assembly.GetExecutingAssembly().Location; System.IO.FileInfo fi = new System.IO.FileInfo(strpath); Console.WriteLine(fi.CreationTime); } }

it will not give you the build date but it will give you the creation date on the client machine

hope this helps

Answer 4

__DATE__ is a define which is evaluated at compile time, so you can have the build date available as string - maybe for diagnostics or an about dialog or whatever.

Answer 5

If you use "1.0.*.*" as the assemblyVersion in your AssemblyInfo.cs file, then the build (3rd) number will give you the date, while the revision (4th) number will be the time.   I forget the exact format, but I think it's something like Build = days since 1/1/1970, and Revision=(seconds since 12mid)/2

 

Answer 6

OK, I was close... It is "days since 1/1/2000" -- this code will work:

Assembly assem = Assembly.GetExecutingAssembly(); Version vers = assem.GetName().Version; DateTime buildDate = new DateTime(2000, 1, 1).AddDays(vers.Build).AddSeconds(vers.Revision * 2); Console.WriteLine(vers.ToString()); Console.WriteLine(buildDate.ToString());
