Removing a known sub-string from a string

I'm having a string "Kishore kumar karaoke tracks", from which I want to remove the substring 'karaoke tracks'. I want the output as 'Kishore kumar'.

For this purpose, I'm using the following line of code:

artist = artist.TrimEnd(new char[] {'k','a','r','a','o','k','e', ' ', 't','r','a','c','k','s'});

But, I'm getting the output as 'Kishore kum' i.e. i'm not getting the last 2 characters 'ar'.

Where I'm going wrong?

in Trim, you defined which chars you want to delete from artist. But it has r and a chars too.

So when karaoke tracks ends, next is kumar's ar, if you understood what I mean.

You can use replace function as others explained.

artist = artist.Replace("karaoke tracks", string.Empty).Trim();

You could also do this if you wanted to ignore case:

artist = Regex.Replace(artist, "karaoke tracks", string.Empty, RegexOptions.IgnoreCase).Trim();

You can also do like this

artist.Replace(" karaoke tracks",string.Empty);

Using a simple String.Replace works too:

artist = artist.Replace(" karaoke tracks", "");

Note I added a space in the front, so the result is "Kishore kumar", rather than "Kishore kumar ".

You can just do artist = artist.Replace("karaoke tracks", "").Trim()
