FileBuildPart Property

FileVersionInfo.FileBuildPart Property

Gets the build number of the file.

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

public int FileBuildPart { get; }

Property Value

Type: System.Int32
A value representing the build number of the file 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 file version number is a 64-bit number that holds the version number for a file as follows:

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;
}
