Replace ignoring case

Question

Hi,

How can I replace a string ignoring it's case to another ?

For example: I need that

ACEFii, ACEFII, acefii, ACEfii and all others variations to be replace by ACEFII (to avoid user mistyping..)

Answer 1

I think the StringComparison.CurrentCultureIgnoreCase could solve your problem.

Or Alternatively use Regex.Replace and use (?i) which will ignore case. Or use the IgnoreCase option.

You can use String.ToUpper Method ().

Answer 5

            string val = "AStringValue";

            if (val.Equals("astringvalue", StringComparison.InvariantCultureIgnoreCase))
            {
            }

This example ignores case.

Also,

String val = "AStringValue";
if (Regex.IsMatch(val, "astringvalue", RegexOptions.IgnoreCase))
{
}

Answer 7

Do you need to look "acefii" or similar in sentence or from text or just single word?

If you look close at his post, the strings are all the same except for case, and from what I gathered he just wants it to end up as upper casing. You don't need to replace characters to do that.
