Hi UiPath,

How can I print my variable List in a Messagebox activity?

Attached is the project I am working on

I tried using the String.Join

Thank!

Hi @alvin.c.apostol26

Have you tried with this expression

String.Join(" ",YourList})

Hello @alvin.c.apostol26 ,

To print a List Variable in Message box use :
String.Join(“,”,YourListVariable).ToString

you can only show the message in message box having datatype string or integer, since you get a list of datarows you wont be able to show that in mesage box, to show that you better have to save it to a datatable and using output datatable convert the datatable to string and can view in message box

please find updated image below::
The out from output datatable is given to message box

@alvin.c.apostol26 - try this it will work for u
string.join(System.Environment.NewLine, dt_YourDataTable.Rows.Cast(of DataRow).Select(function(row) string.join(“,”,row.ItemArray))))

Put this expression in Msg Box & replace dt_YourDataTable with your DataTable Variable.
