Question

我想连接mysql phpmyadmin数据库并在我的应用程序中获取数据在vb.net但我无法连接。我收到无法与指定主机连接的错误消息。当我在浏览器中输入10.1.1.53/phpmyadmin时，我能够打开我的所有数据库，没有任何密码或用户名，但当我尝试通过单击按钮连接我的vb.net应用程序时，我收到了错误消息。这是我的代码。请帮帮我。

ImportsMySql.Data.MySqlClient

PublicClasslogin
Dim con AsMySqlConnection
Dim reader AsMySqlDataReader
Dim command AsMySqlCommand
DimmyconAsString = "server=10.1.1.53/phpmyadmin;database=dbtest"
PrivateSubbtnlogin_Click(sender AsObject, e AsEventArgs) Handlesbtnlogin.Click
login()
EndSub
PrivateSublogin()
con = NewMySqlConnection
con.ConnectionString = mycon
Try
con.Open()
Catch ex As Exception

EndTry
EndSub

PrivateSubbtnexit_Click(sender AsObject, e AsEventArgs) Handlesbtnexit.Click
Me.Close()
EndSub

EndClass

Answer 1

Public Sub login()

    Dim DatabaseName As String = "dbtest"
    Dim server As String = "10.1.1.53"
    Dim userName As String = "username"
    Dim password1 As String = "pass"

    If Not conn Is Nothing Then conn.Close()
    conn.ConnectionString = String.Format("server={0}; user id={1}; password={2}; database={3}; pooling=false", server, userName, password1, DatabaseName)

    Try
        conn.Open()
        ' MsgBox("Connected")
    Catch ex As Exception
        MsgBox(ex.Message)
    End Try
    'conn.Close()
End Sub

你给我的那个是DimmyconAsString＆lt;＆lt;那是错字吗？

收到错误消息无法连接到vb.net中的任何指定的mysql主机
