Personally I would check the source and correct the issue there. Is sounds like the first issue it that the values are being inserted into dr incorrectly.

To fix it, I would just use .replace:

rst.Add(string.Format("{0}",dr["Practice_short_name"].Replace("[\[\]\"]","")));

I won't post as a solution as I'm sure another expert will have another idea

It depends on your data source: it looks like the unwanted characters are coming from there. If they are, then the best way is to remove them at source, but if you can't do that then either a substring:

C#

string base = dr["Practice_short_name"].ToString();
rst.Add(base.Substring(2, base.Length - 4));

if every single value is the same, or a Regex if not.
