Question

.Net application calls Stored Procedure and returns collection which is stored as ‘result.’ I want to be able to group the results by ‘CreatorLineOfBusinessID’. It returns that field along with several other fields. I would like to use a LINQ query on the ‘result‘ data set. Thanks in advance.

Dim result As IEnumerable(Of eRefer_Reports.uspReport_ReferralsSentBetweenLinesOfBusinessResult)

             strFromLOBID = " "
            Session("FromLineOfBusiness") = strFromLOBID
            strToLOBID = " "
            Session("ToLineOfBusiness") = strToLOBID

            result = repository.GetQueryResults(CDate(Me.txtStartDate.Text), CDate(Me.txtEndDate.Text), strFromLOBID, strToLOBID)
            BindGridView(result)          

Answer 1

Dim query = result.GroupBy(Function(x) x.ID).ToList()

Should group the results the way you want.
