Property Value

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("%systemroot%\\Notepad.exe");

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