Hi @MitheshBolla ,

You could try and use the Below Expression in an Assign Activity, it is a Conversion of the Linq in vb.net to c# :

OutputDT = DT.AsEnumerable().Select(c=>OutputDT.Rows.Add(c.ItemArray.Select(x=>x.ToString().Trim().Replace("Milestone","YES")).ToArray())).CopyToDataTable()

Here DT in the Input Datatable, OutputDT is the Datatable variable which needs to be Initialised with the Clone of Input Datatable DT before using the above Expression.


For this Particular Case, we could also Try with a Regex/String Replace Method, where we First Convert the Datatable to String, Replace the String "Milestone" with "Yes", then use Generate Datatable Activity to Convert the String back to a Datatable.

As it is a Mass Update, it shouldn’t be a problem.

for c# it is usually to use x => x syntac for the VB.Net Function (x) x equivalent
we also have to respect the propert syntax (case sensitive, () cannot be ommited)…
On the end we do close with a ;

It could be the case that there is a confusion for current UiPath .Net Infrastructure and LINQ Query syntax.

Which error you do get for which adapted LINQ?

with which activity it is possible?

Bro thanks a lot . This worked.

If there are 2 to 4 replaces that is

“MilestoneFailed” as “No”

Blanks as “NA”

same code i need to assign 3 times or add these two changes in single assign?

OutputDT = DT.AsEnumerable().Select(c=>OutputDT.Rows.Add(c.ItemArray.Select(x=>x.ToString().Trim().Replace(“Milestone”,“YES”).Replace(“MilestoneFailed”,“No”)).ToArray())).CopyToDataTable().

for multiple replace conditions how to write bro

@MitheshBolla , Try using the Milestone failed as the First Replace and then just the Milestone like below :


Let us know if this doesn’t work.
