FileVersionInfo.GetVersionInfo("~/bin/MyFile.dll").FileVersion

When I make this call, I get the following error:

"Cannot evaluate expression because the code of the current method is optimized"

Is there any way to get the version of a DLL in an ASP web app? Code behind is VB... but I'm guessing it doesn't matter if it's VB or C#.

It must work in RELEASE, and when the app is deployed to a production environment. I've searched the interwebs but only found a lot of DEBUG vs. RELEASE config.

I've also tried this with no help:

Thanks in advance!

  • This is NOT a duplicate. The link posted by tonythewest mentions nothing about the error I am receiving. I also tried using AssemblyName.GetAssemblyName(@"c:\path\to\file.dll").Version and I receive the exact same exception: "Cannot obtain value of the local variable or argument because it is not available at this instruction pointer, possibly because it has been optimized away." – PaulyWally Sep 18 '17 at 12:50

FileVersionInfo representing the version information associated with the specified file.

I try this on my custom dll, this work correctly

    FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(@"C:\HBK.SystemCore.dll"); 

    string version = fvi.FileVersion;
