@poana can i have screenshot of your assign activity.

this is my formula where i get the error

From col In dt.Columns.Cast( Of System.Data.DataColumn)
Where dt.AsEnumerable().All(Function(x) x.IsNull(Convert.“ToString”(col.ColumnName)))
Select col.ColumnName").ToArray()

i don t get where to put the double quote, tried everything

@poana

Why you put double quotes for “Tostring” ?

Remove that quotes and try it.

Firts it was simple then i changed it because i didn t get the qoute error.

@poana

Try like this:

x.IsNull(col.ColumnName.Tostring)

Hey @lakshman i tried and i have another error " End of expresion expected"

@poana now just try this
From col In dt.Columns.Cast( Of System.Data.DataColumn)
Where dt.AsEnumerable().All(Function(x) x.IsNull(Convert.ToString(col.ColumnName)))
Select col.ColumnName.ToArray() i used like this it didn’t show me any error
