vb.net - Late binding in query -

-

yes know option strict , use quite often. issue stemming linq query , can't seem figure out how throwing up. wanting datarows in given table row's id equals id give it. query works fine without option strict on rows need, want have on.

the error: option strict on disallow's late binding

here's have right now...

  dim crows() datarow = (from crow in masterdataset.tables(1).rows crow(childtablekey) = intparid).toarray

the error happening underneath: crow(childtablekey)

i know error mean's well, can't seem figure how stop seeing error. have tried casting , such well...

try using 

in masterdataset.tables(1) ctype(crow(childtablekey), integer)

instead of

in masterdataset.tables(1).rows crow(childtablekey)

the example below working me option strict:

    dim ds new dataset     dim dt new datatable     ds.tables.add(dt)     dim dc new datacolumn     dc.datatype = gettype(system.int32)     dt.columns.add(dc)     dim dr datarow = dt.newrow     dr(0) = 10     dt.rows.add(dr)      dim rows datarow() = (from r in ds.tables(0) ctype(r(0), integer) = 10).toarray
