Contains not a member of String()

[adext]

Hello

I converted my project from legacy to windows and I am getting an error that I did not have before the conversion.

Here is the expression: DT.AsEnumerable().Where(Function(r) peopleList.Contains(r.Field(Of String)(“Name”))).ToArray()

and here is the error message : “Contains is not a member of String()”

I don’t understand why it wouldn’t be available anymore ? It’s even on official documentation

Thank you

@adext

DT.AsEnumerable().Where(Function(r) peopleList.Contains(r.Field(Of String)(“Name”))).ToArray()

The source of the error is the variable peopleList which seems to be converted to a string instead of being a List.

What if you try : enforcing list type (peopleList.ToList)

DT.AsEnumerable().Where(Function(r) peopleList.ToList.Contains(r.Field(Of String)(“Name”))).ToArray()
