Hi,

There are some ways to achieve it. I’ll show one of them as the following.

arr : String[] type
list : List<string> type

I tried this way,but can’t create a List type.

Hi,

Can you select “String” as the following image?

Hi,
you can assign to a cell, you can try this method:
str1=“Your Value”
str2=“Your Value”
String.Concat(str1,str2)

Thank you ,it works well now.

And could you have a look at the picture below. Do you know ,does this way work well ? and how?

Thank you ,i 'll have a try.

Hi,

You can also use Append method. This returns IEnumerable<T> type, so it will be the following.

arr = {"1", "2"}
arr = arr.Append(str1).ToArray
arr = arr.Append(str2).ToArray
