Property Value

true if the file is patched; otherwise, false.

The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it displays the state of the Boolean IsPatched in a text box. This code assumes textBox1 has been instantiated.


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

    // Print whether the file has a patch installed.
    textBox1.Text = "File has patch installed: " + myFileVersionInfo.IsPatched;
}
