Not able to get value of a field from File Properties !!

Question

The thing is, I am testing an application where we check versions, builds and some other things in file properties of exe, jar and DLLs.(Please see the source file image for details). I use GetFileVersionInfo method for checking the fields specified above.

The problem is, "Time Stamp" field in file properties of a file is not windows owned field like others, but you can say explicit. FileVersionInfo is not returning the value stored for that field.

Please help me.

Thanks C-Sharpians :)
