How to create use StringBuilder in asp.net c#?

StringBuilder is most flexible because it can span multiple statements. The default constructor creates a buffer 16 bytes long, which grows as needed. We can specify an initialize and also maximize size if needed.

          try
            {
               System.Text.StringBuilder sb = new System.Text.StringBuilder(25);
               sb.Append("Learn");
               sb.Append(".net");
               sb.Append("skills");
               sb.Append("through");
                sb.Append(" infinetsoft");
                Console.WriteLine(sb.ToString());
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }

Output:
