 <p>Maybe you could do this:</p> <pre><code>tagFile.Save() if(tagFile.Tag.Title == infoVar1) { MessageBox.Show("Tags saved successfully"); } </code></pre> <p>After saving the tags into a file, you can validate with some attribute like Title, album, etc. :)</p> <p>A simple question, which version(of taglib#) are you using?</p>
