public int ProductMajorPart { get; }

Property Value

Type: System.Int32
A value representing the major part of the product version number or null if the file did not contain version information.

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:

This property gets the first set of 16 bits.

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

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

    // Print the product major part number.
    textBox1.Text = "Product major part number: " + myFileVersionInfo.ProductMajorPart;
}
