Imports System.Data
Imports System.Data.SqlClient
Partial Class Reg
    Inherits System.Web.UI.Page
    Dim myConn As SqlConnection
    Dim cmd As SqlCommand
    Dim sqlstring, ide, name, fname, cty As String

    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

    End Sub

    Protected Sub submitbtn_Click(sender As Object, e As EventArgs) Handles submitbtn.Click
        ide = idbox.Text
        name = namebox.Text
        fname = fatherbox.Text
        cty = countrybox.Text

        myConn = New SqlConnection("Data Source=(localdb)\v11.0;Initial Catalog=C:\USERS\DREAM THEATER\DOCUMENTS\VISUAL STUDIO 2012\WEBSITES\WEBAPP\APP_DATA\DATAAJIT.MDF;Integrated Security=True")
        myConn.Open()

        sqlstring = " INSERT INTO Test (Id,name,father,country) VALUES (" + ide + ",'" + name + "','" + fname + "','" + cty + "')"
        cmd = New SqlCommand(sqlstring, myConn)
        cmd.ExecuteNonQuery()
        myConn.Close()
        Response.Redirect(Request.RawUrl, True)

    End Sub
End Class

当我运行此代码时出现错误如下

SQl异常未被用户代码
处理   无法打开数据库＆＃34; C：\ USERS \ DREAM THEATER \ DOCUMENTS \ VISUAL STUDIO 2012 \ WEBSITES \ WEBAPP \ APP_DATA \ DATAAJIT.MDF＆＃34;登录请求。登录失败。

登录失败

我该如何解决这个问题？

Answer 1

在web.config中，在Initial Catalog中输入数据库的名称，而不是.mdf的完整路径。

另外，因为您有Integrated security = true，请检查您的用户（在这种情况下）是否存在于数据库的安全部分，登录

打开MDF时“用户登录失败”
