老师好。下面的两组代码，哪个更高效些？
第一组：
dim bh as string =e.row("编号")
for each dr as row in tables("表A").rows
if dr("编号")=bh then
dr.checked = true
end if
next
第二组：
dim bh as string =e.row("编号")
dim drs as list(of datarow) =datatables("表A").select("[编号]='" & bh & "'")
for each dr as datarow in drs
dim index as integer = tables("表A").findrow(dr)
tables("表A").rows(index).checked = true
next
