FileVersionInfo.ProductVersion Property

Typically, a version number is displayed as "major number.minor number.build number.private part number". A product version number is a 64-bit number that holds the version number as follows:

• The first 16 bits are the ProductMajorPart number.

• The next 16 bits are the ProductMinorPart number.

• The third set of 16 bits are the ProductBuildPart number.

• The last 16 bits are the ProductPrivatePart number.

The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it prints the ProductVersion in a text box. This code assumes textBox1 has been instantiated.

private void GetProductVersion()
{
    // Get the file version for the notepad.
    FileVersionInfo myFileVersionInfo =
        FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\\Notepad.exe");

    // Print the product version number.
    textBox1.Text = "Product version number: " + myFileVersionInfo.ProductVersion;
 }
