C# .Trim not working for some reason

Alright, so basically, I'm trimming a string then making it lowercase. The lowercase part works perfectly well, but the sentence doesn't get trimmed. Any clue?

var result12 = TrimTheSentence("   John.   Doe@ gmaiL . cOm");

//the method is 

    public static string TrimTheSentence(string givenString)
    {
        givenString = givenString.Trim();
        return givenString.ToLower();

You can use a string extension method to remove white space within a string.

public static string RemoveWhiteSpaces(this string input)
{
    return Regex.Replace(input, @"\s+", "");
}

This is what you are looking for, you could shorten your method to just one line:

return givenString.Replace(" ", "").ToLower();

Trim() removes blank spaces from front and end of the string. It will not remove spaces that are in the string.

Examples:

"  Test String".Trim(); //Output: "Test String", it will remove only the leading spaces, but not the space between Test and String.
" Test String   ".Trim(); //Output: "Test String", it will remove leading and trailing spaces.

Trim removes spaces from the start/end, not from the entire string. Try:

return givenString.Replace(" ", "");
