You've too use a replace function.

This pieco of code shows how you can do that.

C#

p = p.Replace("  ", string.Empty);
p = p.Replace(Environment.NewLine, string.Empty);
p = p.Replace("\\t", string.Empty);
p = p.Replace(" {", "{");
p = p.Replace(" :", ":");
p = p.Replace(": ", ":");
p = p.Replace(", ", ",");
p = p.Replace("; ", ";");
p = p.Replace(";}", "}");
return p;

Don't. Use parametrized queries instead:
Try:

using (SqlConnection con = new SqlConnection(strConnect))
    {
    con.Open();
    using (SqlCommand com = new SqlCommand("SELECT iD, description FROM PurchaseTypes WHERE name=@NM", con))
        {
        com.Parameters.AddWithValue("@NM", myTextBoxWithHisNameInIt.Text);
        using (SqlDataReader reader = com.ExecuteReader())
            {
            while (reader.Read())
                {
                int id = (int) reader["iD"];
                string desc = (string) reader["description"];
                Console.WriteLine("ID: {0}\n    {1}", iD, desc);
                }
            }
        }
    }

Try this.

SELECT REPLACE(REPLACE(field_name,'-',''),'_','') from table_name

I remember doing that once! 5+
(Not proud of if, but it was the easiest way to go.)
