copied!<p>To test the suggestion by Romoku of using <code>StringBuilder</code> I have produced the following code.</p> <pre><code> public static void Reverse(string x) { string text = x; string reverse = string.Empty; foreach (char ch in text) { reverse = ch + reverse; } Console.WriteLine(reverse); } public static void ReverseFast(string x) { string text = x; StringBuilder reverse = new StringBuilder(); for (int i = text.Length - 1; i >= 0; i--) { reverse.Append(text[i]); } Console.WriteLine(reverse); } public static void Main(string[] args) { int abcx = 100; // amount of abc's string abc = ""; for (int i = 0; i < abcx; i++) abc += "abcdefghijklmnopqrstuvwxyz"; var x = new System.Diagnostics.Stopwatch(); x.Start(); Reverse(abc); x.Stop(); string ReverseMethod = "Reverse Method: " + x.ElapsedMilliseconds.ToString(); x.Restart(); ReverseFast(abc); x.Stop(); Console.Clear(); Console.WriteLine("Method | Milliseconds"); Console.WriteLine(ReverseMethod); Console.WriteLine("ReverseFast Method: " + x.ElapsedMilliseconds.ToString()); System.Console.Read(); } </code></pre> <p>On my computer these are the speeds I get per amount of alphabet(s).</p> <p>100 ABC(s) Reverse ~5-10ms FastReverse ~5-15ms</p> <p>1000 ABC(s) Reverse ~120ms FastReverse ~20ms</p> <p>10000 ABC(s) Reverse <strong>~16,852ms!!!</strong> FastReverse ~262ms</p> <p>These time results will vary greatly depending on the computer but one thing is for certain if you are processing more than 100k characters you are insane for not using <code>StringBuilder</code>! On the other hand if you are processing less than 2000 characters the overhead from the <code>StringBuilder</code> definitely seems to catch up with its performance boost.</p>
