Property Value

Type: System.Int32

A value representing the build number of the file or null if the file did not contain version information.

This property gets the third set of 16 bits.

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

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

    // Print the file build number.
    textBox1.Text = "File build number: " + myFileVersionInfo.FileBuildPart;
