[c#] how to get file version info.

[MRMAN]

Hello.

I am making a tool to copy new files from folder a to folder b.
If a file exists in the b then i want to compare the version number of the file in a and b and if b is a out of date version then it will copy a to b.

The problem is i don't know how to get the version number.

I can get the mod date and time, Attributes and other stuff but can't work out the version.

Does anyone know how.

Thank you.

Example 3 shows you how to get that product version. To get a different field change the end of the subBlock string you pass to VerQuryValue.
For example:
change:
string spv = @"\StringFileInfo\" + subBlock[0].ToString("X4") + subBlock[1].ToString("X4") + @"\ProductVersion";

to:
string spv = @"\StringFileInfo\" + subBlock[0].ToString("X4") + subBlock[1].ToString("X4") + @"\CompanyName";

etc...

Available fields are:
"CompanyName"
"FileDescription"
"FileVersion"
"InternalName"
"LegalCopyright"
"OriginalFileName"
"ProductName"
"ProductVersion"
