FileVersionInfo.FilePrivatePart Property

Gets the file private part number.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

public int FilePrivatePart { get; }

Property Value

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

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

  • The first 16 bits are the FileMajorPart number.

  • The next 16 bits are the FileMinorPart number.

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

  • The last 16 bits are the FilePrivatePart number.

This property gets the last set of 16 bits.

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

private void GetFilePrivatePart() {
    // Get the file version for the notepad.
    FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo("%systemroot%\\Notepad.exe");

    // Print the file private part number.
    textBox1.Text = "File private part number: " + myFileVersionInfo.FilePrivatePart;
