There are many ways through which we can reverse a string but I have come up with a single line of code through which we can easily achieve this.

Formula to reverse a string is-

string_tobe_reversed.AsEnumerable.Reverse.ToArray

Here, in the above formula-

  1. Replace the string_tobe_reversed with your string.
  2. It would be return array of char.
  • Lets see now the implementation in UiPath*

Step 1:- Drag an assign activity and pass a value that you like to reverse.

string.Join(“”,str_text.ToCharArray.Reverse)

I tried doing this method but it says

For Each: Object reference not set to an instance of an object.

please check if your variable which you are trying to reverse is having some value or it is null… in general this error comes when the variable is having null value

Check this xaml for your reference
