M mindful Active Member Licensed User Mar 23, 2017 #1 Which method offers the best performance to join together two strings ? 1. Code: Copy Dim finalString As String = String1 & String2 2. Code: Copy Dim finalString As String = $"${String1}${String2}"$ 3. Code: Copy Dim sb As StringBuilder sb.Initialize sb.Append(String1) sb.Append(String2) Dim finalString As String = sb.ToString I am looking for a method that will be used in general (short, long, very long strings which are made from 2 strings or more) ... for now I am using the 1st and the 2nd but I saw a post (can't find it) that suggested that for long strings composed of many parts (not just two) it is performance wise to use the 3rd method ...

Erel B4X founder Staff member Licensed User Longtime User Mar 24, 2017 #3 For a few strings the difference will not matter. If there are many concatenations then you should definitely use StringBuilder. The relevant discussion: https://www.b4x.com/android/forum/threads/get-a-random-string.75903/#post-481749 (StringBuilder is 100 times faster). Upvote 0
