How to fix weird conversion from String.ToUpper () to C #

Question

I am trying to show something like "contáctenos" in uppercase, but when I use the string.toUpper () method, I have a strange result "CONTACTENOS" instead of "CONTÁCTENOS".

The culture page is set correctly for es-ES and niculture. How can I get the correct result, if possible, without using a regular expression or replacement.

Thanks in advance...

Answer 1

using:

.ToUpper(new CultureInfo("es-ES", false));
