How to compare strings with case insensitive and accent insensitive

Alright this is done easily at SQL server

However I would like to do the same at C# .NET

Answer 1

You can use string.Compare with the overload which takes the proper CultureInfo and CompareOptions:

string.Compare(s1, s2, CultureInfo.CurrentCulture, CompareOptions.IgnoreNonSpace |
                                                   CompareOptions.IgnoreCase);

Edit:

As for your question on CultureInfo, from MSDN:

The comparison uses the culture parameter to obtain culture-specific information, such as casing rules and the alphabetical order of individual characters. For example, a particular culture could specify that certain combinations of characters be treated as a single character, that uppercase and lowercase characters be compared in a particular way, or that the sort order of a character depends on the characters that precede or follow it.
