Adding element on top of which array?

a simple array of strings.
I need to add a string at the first position.
CAn you help me?


As per my knowledge you can not add the element in the begining of array. but you can add at end of the array.

if you want to modify/change the value in array you can do like below.

Array[0] = “value”;


Hi @CamiCat
We can’t insert element directly in the array at certain Position, but you can do one thing
Store your new value in Variable Lets say.
NewVar = "NewValue"
and Suppose your array is SampleArr.
Now, Convert this array in String and add your New Value in It Like this,
Str= NewVar+","+String.Join(",",SampleArr) .
Now split your string value using Str.Split(CChar(",")) and store this value in NewArray.
So your newvalue will be at first Position.
I hope this will help you.
Thanks & Regards

Hi @CamiCat,
First you need to convert your array to list using the variablename.toList . And then use the .add method to specify where you want to insert the element and then convert the list back to array.:slight_smile:

Hi cami
Actually we won’t able to do that in a array rather we need to use a list variable
As Array is a fixed structure firstvwe won’t able to add a new element in even it is defined with a size
And so we can only insert values to a array with Arrayvariable.Insert(indexposition,”value”) and not possible to add an element

And to do that we need to use a List variable
We can use the same here and it is similar to array but more effective as we can add n number of element whenever we want
And to add a element in list variable
Listvariable.Insert(indexposition,”value”) with a simple assign activity

For more details on this

Cheers @CamiCat
