Ignoring accented letters in string comparison

Question

I need to compare 2 strings in C# and treat accented letters the same as non-accented letters. For example:

string s1 = \"hello\";
string s2 = \"héllo\";

s1         


        

Answer 1

If you don't need to convert the string and you just want to check for equality you can use

string s1 = "hello";
string s2 = "héllo";

if (String.Compare(s1, s2, CultureInfo.CurrentCulture, CompareOptions.IgnoreNonSpace) == 0)
{
    // both strings are equal
}

or if you want the comparison to be case insensitive as well

string s1 = "HEllO";
string s2 = "héLLo";

if (String.Compare(s1, s2, CultureInfo.CurrentCulture, CompareOptions.IgnoreNonSpace | CompareOptions.IgnoreCase) == 0)
{
    // both strings are equal
}
