帮助中的代码，我改成数据库读取用户名和密码， 提示错误：
此主题相关图片如下：微信截图_20170428222414.png
Dim Verified As Boolean '用于标记用户是否通过了身份验证
Dim UserName As String = e.Cookies("username") '从cookie中获取用户名
Dim Password As String = e.Cookies("password") '从cookie中获取用户密码
If e.Path = "logon.htm" '如果是通过登录页面访问,从PostValues即可中提取用户名和密码
If e.PostValues.ContainsKey("username") AndAlso e.PostValues.ContainsKey("password") Then
UserName = e.PostValues("username")
Password = e.PostValues("password")
End If
End If
Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.C
cmd.CommandText = "SELEC T name,password From {用户数据表}"
dt = cmd.ExecuteReader()
Dim dr As DataRow = dt.SQLFind("[Name] = '" & UserName & "'")
If Password = dr("Password") Then
Verified = True
Else
End If
If Verified AndAlso e.Path = "logon.htm" Then '如果用户访问的是登录页,且身份验证成功
wb.AppendCookie("username",UserName) '将用户名和密码写入cookie
wb.AppendCookie("password",Password)
wb.InsertHTML("<meta http-equiv='Refresh' c>") '直接跳转到首页
e.WriteString(wb.Build) '生成网页
Return '必须的
ElseIf Verified = False AndAlso e.Path <> "logon.htm" Then '如果用户身份验证失败,且访问的不是登录页面
wb.InsertHTML("<meta http-equiv='Refresh' c>") '那么直接跳转到登录页面
e.WriteString(wb.Build) '生成网页
Return '必须的
End If
