我有一些麻煩得到一個循環,看看更多,然後只是第一行數據。所引用的數據集函數可以毫無問題地獲得所有必需的行,因此我確定問題必須出現在代碼中。如何遍歷數據表中的行?
Dim dtLogin As System.Data.DataTable
Dim userDetails As New dsMembersTableAdapters.mi_membersTableAdapter
Dim rowsLogin As System.Data.DataRow
'Fill datatable using method from dataset
dtLogin = userDetails.GetUserData()
'Find cotrols hidden in Login View
Dim user As String = txtUser.Text
Dim pass As String = txtPass.Text
'Search all users
For Each rowsLogin In dtLogin.Rows
'Find Username Entered
If user = dtLogin.Rows.Item(0).Item(1) Then
'Checks users password matches
If pass = dtLogin.Rows.Item(0).Item(2) Then
If dtLogin.Rows.Item(0).Item(6) = 1 Then
'Log User In
FormsAuthentication.RedirectFromLoginPage(dtLogin.Rows.Item(0).Item(1), True)
Else
'Account Not Active Message
lblValidation.Text = "There is a problem with your account, please contact the website administration"
End If
Else
'Incorrect Password Message
lblValidation.Text = "Incorrect Password"
End If
Else
'No User in DB Message
lblValidation.Text = "No User Found" + dtLogin.Rows.Item(0).Item(1)
End If
Next
如果任何人都可以幫助我,或者直接指向我的rihgt直接,那太棒了!在此先感謝:)
張貼的答案看起來是正確的......但爲什麼你循環所有的用戶數據來驗證一個用戶? – 2013-02-12 01:58:05
嘗試從不使用索引...如果您更改了選擇語句的順序,您的所有代碼都將被破壞...請參閱我對我的回答的評論,並使用行[]'代替。 –
