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.

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;
}
