这是我卡住的地方,我尝试了两种不同的方法,但仍然无效:

Categories.DataSource = objDT.AsEnumerable() _

    .GroupBy(Function(v) v.Field(Of String)("Attendee")) _
    .Select(Function(g) Attendee = g.Key)

要么

Categories.DataSource = objDT.Rows.Cast(Of DataRow)().AsEnumerable _
    .Select New Object(){ Function(r As DataRow) Attendee = r.Field(Of String)("Attendee"), Item = r.Field(Of String)("Item")} _
.GroupBy( Function(v) v.Category) _
.Select( …
