Question

I have a Multi-Line text box that I can paste a list of any text items into, like this:

555-555-1212
I want's a lemon's.
google.com
1&1 Hosting

I also have a text box next to it that I can add comma separated strings that I want removed from all items in my list, like this:

-,$,!,@,#,$,%,^,&,*,(,),.com,.net,.org

I am trying to figure out how to scrub each of these strings(or whatever other strings I put in that second text box) from each of the strings in my textbox List.

Any ideas? I know how to get the List into a List-string, but not sure how to scrub that string.

This is what I have so far…but I am getting red squigglies:

List<string> removeChars = new List<string>(textBox6.Text.Split(','));                 
for (int i = 0; i < sortBox1.Count; i++)
{
    sortBox1[i] = Regex.Replace(sortBox1[i], removeChars, "").Trim();
}

Answer 1

Use String.Replace on every string in the unwanted-list for every line in Textbox.Lines.

string[] replaceStrings = txtUnwanted.Text.Split(',');
List<string> lines = new List<string>(textBox1.Lines);
for (int i = 0; i < lines.Count; i++)
    foreach (string repl in replaceStrings)
        lines[i] = lines[i].Replace(repl, "");
