Body
I want to replace some invalid characters in the name of a file uploaded to my application. I've searched up to something on the internet and found some complex algorithms to do it, here's one: <pre><code> public static string RemoverAcentuacao(string palavra) { string palavraSemAcento = null; string caracterComAcento = "áàãâäéèêëíìîïóòõôöúùûüçáàãâÄéèêëíìîïóòõÖôúùûÜç, ?&:/!;ºª%‘’()\"”“"; string caracterSemAcento = "aaaaaeeeeiiiiooooouuuucAAAAAEEEEIIIIOOOOOUUUUC___________________"; if (!String.IsNullOrEmpty(palavra)) { for (int i = 0; i < palavra.Length; i++) { if (caracterComAcento.IndexOf(Convert.ToChar(palavra.Substring(i, 1))) >= 0) { int car = caracterComAcento.IndexOf(Convert.ToChar(palavra.Substring(i, 1))); palavraSemAcento += caracterSemAcento.Substring(car, 1); } else { palavraSemAcento += palavra.Substring(i, 1); } } string[] cEspeciais = { "#39", "---", "--", "'", "#", "\r\n", "\n", "\r" }; for (int q = 0; q < cEspeciais.Length; q++) { palavraSemAcento = palavraSemAcento.Replace(cEspeciais[q], "-"); } for (int x = (cEspeciais.Length - 1); x > -1; x--) { palavraSemAcento = palavraSemAcento.Replace(cEspeciais[x], "-"); } palavraSemAcento = palavraSemAcento.Replace("+", "-").Replace(Environment.NewLine, "").TrimStart('-').TrimEnd('-').Replace("", "-").Replace("<-i>", "-").Replace(" ", "").Replace("--", "-"); } else { palavraSemAcento = "indefinido"; } return palavraSemAcento.ToLower(); } </code></pre> There's a way to do it with a less complex algorithm? I think this algorithm is very complex to something not too complex, but I can't think in something diferent of this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
