Working with Strings

  • Strings are immutable. Once they are created, if they are modified, the previous version is thrown away, and a new version is created.
  • To join strings, use & (preferred) or +
  • String.Compare() is used to compare strings
  • .Insert and .Remove, .ToUpper and .ToLower, and .Split and .Join are just a few of the ways to deal with strings
  • A few more helpful, self-explanatory, functions:
    • .StartsWith and .EndsWith
    • .SubString
    • .PadLeft and .PadRight
    • .IndexOf and .IndexOfAny
    • .LastIndexOf and .LastIndexOfAny
  • Use the StringBuilder class if your strings will be modified multiple times
  • Using StringBuilder reduces memory usage
  • Some StringBuilder functions:
    • .Append
    • .Insert
    • .Remove
    • .Replace
