Split separates strings and ignore/remove other delimited string

I'm reading a comma-delimited list of strings from a config file. I need to check the following steps

1) check to see if the string has `[`, if it is then remove or ignore...
2) split `,` `-` //which i am doing below...

Here is what I able to do so far;

string mediaString = "Cnn-[news],msnbc";

string[] split = mediaString.Split(new Char[] { ',', '-' }); //gets me the bracket

what I want is to ignore/remove the string which is in the brackets so the end result should be like this:

mediaString = 
                Cnn
                msnbc

Using Linq:

mediaString.Split(new Char[] { ',', '-' }).Where(val => !val.Contains('[')

You can make the test (val.Contains(...)) as sophisticated as you like (e.g. starts and ends with, regular expression, specific values, call an object provided via a DI framework if you want to get all enterprisey).

Without using LINQ or regex: Split your string as you are doing now. Create a data structure of string type for example: List. Run over the results array and for each entry check it contains the specified character, if it doesn't add it to the List. In the end you should have a List with the required result.

This The regex solution is far more elegant but if you cannot use reg ex this one should do it

Use Regex replace to clean your string 

        string str = @"Cnn-[news],msnbc";

        Regex regex = new Regex(@"\[.*\]");
        string cleanStr = regex.Replace(str, "");
        string[] split = cleanStr.Split(new Char[] { ',', '-' });
