Linq query to manipulate a string

[Shilpa_Mohanty]

I have to eliminate .x from any string.
Input - 120.asf.x
12.kiytr.uf90.x
jgui.22980.gtd.x

Required output
120.asf
12.kiytr.uf90
jgui.22980.gtd

Can anyone please help me with a linq query as I have 74k data in excel and using foor loop is very time consuming

Using LINQ to replace specific value in DataTable without For-Each

How to replace a value in datatable in Uipath without using for each row

Hi Welcome back to uipath community There are actually two ways of doing that —first is convert the datatable to a string with the help of OUTPUT DATATABLE ACTIVITY and pass the datatable as input and get the output variable of type string named str_output —now use a normal assign activity like this str_output = str_output.ToString.Replace(“your old value”,” your new value”) Now use GENERATE DATATABLE ACTIVITY and mention the str_output variable as input And get the output with a variabl…

@hasib08

Tried with dt = dt.AsEnumerable().Where(Function(a) a.Field(of string)(“yourcolumnname”).ToString.Replace(“your old value”,” your new value”).ToString).CopyToDatatable()

but here my input column and output column is different

Hi,

Can you try the following expression, for example?

dt = dt.AsEnumerable().Select(Function(r) dt.Clone.LoadDataRow({r("Column1").ToString.Replace(".x",""),r("Column2")},False)).CopyToDataTable()

Sequence1.xaml (7.0 KB)

Note : We need to modify arguments of LoadDataRow for actual datatable.

LINQ isn’t faster than For Each. LINQ still loops, it’s just hidden from you. It’s impossible for data in a table to be updated without looping.
