Hi,
I need to join two tables using linq,

Dim vLINQ = (From DT1 In vDT1.AsEnumerable
            Join DT2 In vDT2.AsEnumerable
            On DT1.Field(Of String)("Key") Equals DT2.Field(Of String)("Key")
            Select new with
            {
               .Key = DT1.Field(Of String)("Key"), 
               .Data1 = DT1.Field(Of String)("Data1"), 
               .Data2 = DT1.Field(Of String)("Data2"),
               .Data3 = DT2.Field(Of String)("Data3"), 
               .Data4 = DT2.Field(Of String)("Data4")
            }).ToList()

I used assign activity to achive this. UIPath showing error as

Option Strict On disallows late binding.

how I can Use this type of LINQ in UIPath?

Using Linq is possible for joining 3 data table. Please find the below sample query.

(from a in Company1 join b in Company2 on a (“EMPId”).Tostring() equals b (“EMPId”).Tostring() join c in Company3 on c.(“EMPId”).Tostring() equals b.(“EMPId”).Tostring()) select a)
