How to filter a date?

Here is a test. I want to know the time of John when on the day I input. For example, I want output John’s time on the “2022-7-20”, which is “11:28”.
So I firstly filter the date, than filter the name. However, the result is Null. (64.4 KB)

Please tell me how to solve :sob:

Str=DT.Asenumerable.Where(Function(r) r(“Name”).Tostring.Equals(“John”) And Also r(“Time”).To string.Contains(YourStringinputDate)).Select(Function(r1) r1(“Time”).Tostring.Split(" "c)(1)).Last()

The file is only a test, actually I need to filter a lot of data, and I need to use “for each row” to get everyone’s right time on everyday. So are there any solutions using “filter”?

DT=DT.Asenumerable.Groupby(Function(r) r(“Name”).Tostring).Select(Function(g) g.where(Function(r1) r1(“Time”).To string.Contains(YourStringinputDate)).First()).Copytodatatable

Can you tell me how to use this? I’m totally a beginner :sob:… If you can give me an example file, I would appreciate it!!!

Hi @aureolegogogo - Can you share that excel file (64.4 KB)

@aureolegogogo - Not able to open it. please share only excel file, that would be enough


Hello @aureolegogogo

Do you need it in the excel itself or you can read the excel and get the values to a datatable variable?

If datatable can be used, then you can use filter datatable activity to meet your requirement? (7.2 KB)

I need to do the filter many times, and the data is complex. I think datatable can not do it. But may be it’s just because I don’t know how to use it.


Not able to open this file it’s invalid file.


you can make the filtering condition of the filter datatable activity dynamic to meet this.

Note: To retrieve the time for a specific person the user should input the name along with the date. I implemented that in the code
