How to delete rows with multiple conditions - LINQ

I need to keep only the rows where at least one value is above 2.

I wanted to do it with LINQ to make it faster, how can I do this?

you need to keep rows where atleast one value is above two. are you comparing all columns valor 1 2 3 4 & 5?

LINQ doesn’t make it faster. The Filter Datatable activity probably uses LINQ anyway.

please try this one


dt_Result = dt_Input.AsEnumerable.Where(Function(row) row(“valor2”).ToString >= “2” or row(“valor3”).ToString >= “2” or row(“valor4” or row(“valor5”).ToString >= “2”).ToString >= “2”).CopyToDataTable



Hi @Gabriel_Wisniewski ,

Instead of deleting rows, we can look at it this way.
Lets focus on the rows that we are interested in retaining.

If you are unsure about the number of columns, and/or its names, or if the rows contain alphanumerical characters, then this might be the solution you are looking for:

Dt.AsEnumerable().Where(Function(w) w.ItemArray.Any(Function(a) If(Integer.TryParse(a.ToString,New Int32),Convert.ToInt32(a),0)>2)).CopyToDataTable()

Hello @Gabriel_Wisniewski

You can use Read Range activity and then use Filter Datatable activity. Then you add multiple conditions in the Filter datatable activity. (To remove you can check the Remove field)

Then Use Write Range to write the updated datatable to Excel.


I should be comparing the columns (valor1,valor2,valor3,valor4,valor5) to 2. If one or more columns has a value above 2, it will be kept. If no value in those columns is above 2 it should be removed.

Initially I tried the Filter DT activity, but it wasn’t handling null values correctly and for some reason a few values in the “valor” columns weren’t being compared as integers properly.

Then I decided to compare them as string but it got too slow and I had to create too many conditions for my exact purpose.

As I mentioned in another comment above, I was having a few complications with the Filter Data Table activity for this purpose, as I had to create too many conditions and it wasn’t handling null values very well.

In the end this helped me solve the problem, thanks.

@Gabriel_Wisniewski Great. mark it as a solution so others can help too., Happy learning
