How to make a vlookup using LINQ

Can you confirm this requirement?

if so have a look here:

[HowTo] Overview on different options for grouping data and processing the groups - News / Tutorials - UiPath Community Forum

whenever an update is to be done on a subset, then filter before update or atleast keep the processing cost as low as possible.

  • when running a statement twice, also it is comsuming processing effort twice

When using the Count > 0 it has no chance to stop when the first was found and checks all. We should rewrite to an Any()

Als we have a chance to rewrite it to a FirstOrDefault and will execute it only 1 time
