Answer 1

You can use one of String.Split methods

Split Method (Char[])
Split Method (Char[], StringSplitOptions)
Split Method (String[], StringSplitOptions)

let's try second option: I'm giving , and space as split chars then on each those character occurrence input string will be split, but there can be empty strings in the results. we can remove them using StringSplitOptions.RemoveEmptyEntries parameter.

string[] tagArray = tags.Split(new char[]{',', ' '},
                               StringSplitOptions.RemoveEmptyEntries);

OR

 string[] tagArray = s.Split(", ".ToCharArray(), 
                               StringSplitOptions.RemoveEmptyEntries);

you can access each tag by:

foreach (var t in tagArray )
{
    lblTags.Text = lblTags.Text + " " + t; // update lable with tag values 
    //System.Diagnostics.Debug.WriteLine(t); // this result can be see on your VS out put window 
}
