Is there an alternative to string.Replace that is case-insensitive in C#?

Is there an alternative to string.Replace that is case-insensitive in C#?

Yes, there are several alternatives to string.Replace that are case-insensitive in C#.

One option is to use the StringComparison enumeration with the Replace method to perform a case-insensitive replace. You can pass StringComparison.OrdinalIgnoreCase or StringComparison.CurrentCultureIgnoreCase as the second argument to the Replace method to ignore the case of the search string. For example:

 string input = "The quick brown fox jumps over the lazy dog"; string search = "quick"; string replacement = "slow"; string output = input.Replace(search, replacement, StringComparison.OrdinalIgnoreCase);

In this example, the Replace method will perform a case-insensitive search for the string "quick" in the input string and replace it with the string "slow".

Another option is to use regular expressions to perform a case-insensitive replace. You can use the Regex.Replace method with the IgnoreCase option to perform a case-insensitive search and replace. For example:

 string input = "The quick brown fox jumps over the lazy dog"; string search = "quick"; string replacement = "slow"; string output = Regex.Replace(input, search, replacement, RegexOptions.IgnoreCase);

In this example, the Regex.Replace method will perform a case-insensitive search for the string "quick" in the input string and replace it with the string "slow". The RegexOptions.IgnoreCase option specifies that the search should be case-insensitive.
