以下示例调用 GetVersionInfo 以获取 FileVersionInfo 记事本的 。 然后，它会在文本框中显示布尔 IsPatched 值的状态。 此代码假定 textBox1 已实例化。

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 = String::Concat( "File has patch installed: ", myFileVersionInfo->IsPatched );
    }

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;
}

Private Sub GetIsPatched()
    ' Get the file version for the notepad.
    Dim myFileVersionInfo As FileVersionInfo = _
        FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\Notepad.exe")
    
    ' Print whether the file has a patch installed.
    textBox1.Text = "File has patch installed: " & myFileVersionInfo.IsPatched
End Sub
