Asp.net 位置0处没有行错误
我有以下代码:Asp.net 位置0处没有行错误,asp.net,sql,vb.net,position,row,Asp.net,Sql,Vb.net,Position,Row,我有以下代码: Do Until i = dsSalesRep.Tables(0).Rows.Count strRepID = dsSalesRep.Tables(0).Rows(i)("repID").ToString strLBP = dsSalesRep.Tables(0).Rows(i)("officename").ToString strLBPEmail = dsSalesRep.Table
Do Until i = dsSalesRep.Tables(0).Rows.Count
strRepID = dsSalesRep.Tables(0).Rows(i)("repID").ToString
strLBP = dsSalesRep.Tables(0).Rows(i)("officename").ToString
strLBPEmail = dsSalesRep.Tables(0).Rows(i)("cemail").ToString
strCCRepEmail = dsSalesRep.Tables(0).Rows(i)("cc1").ToString
strRepName = dsSalesRep.Tables(0).Rows(i)("firstname").ToString & " " & dsSalesRep.Tables(0).Rows(i)("lastname").ToString
strRepEmail = dsSalesRep.Tables(0).Rows(i)("email").ToString
strRepPhone = dsSalesRep.Tables(0).Rows(i)("phone").ToString
searchStr3 = "SELECT * FROM LookupSalesRep WHERE repID='" & strRepID & "'"
Dim SqlAdapter3 As New SqlDataAdapter(searchStr3, myConn2)
Dim dsTerritories As New DataSet
myConn2.Open()
SqlAdapter3.Fill(dsTerritories)
strCountry = dsTerritories.Tables(0).Rows(0)("country").ToString
'strCountry = dsTerritories.Tables(0).Rows.Count.ToString
但是,当我运行网页时,它会给我一个错误:位置0处没有行
但是当我使用代码时
strCountry = dsTerritories.Tables(0).Rows.Count.ToString
strCountry获得正确的行数。请帮助:(您处于一个循环中,在某个点上,表(dsTerritories.Tables(0))为空。请首先检查表是否为空:
If dsTerritories.Tables(0).Rows.Count > 0 Then
strCountry = dsTerritories.Tables(0).Rows(0)("country").ToString
End If
