如何解决类型异常＃System; System.Data.OleDb.OleDbException＃39;

Question

你好我真的不知道我试图将我的vb.net应用程序连接到我的数据库有什么问题但是我有这个例外有什么帮助吗？

这里是代码：

Imports System.Data.OleDb

Module Module1

Sub Main()
    Dim myConnection As OleDbConnection
    Dim myCommand As OleDbCommand
    Dim dr As OleDbDataReader

    myConnection = New OleDbConnection("Provider=MSDAORA.1;UserID=hr;password=    adidas1; database=XE")
    'MSDORA is the provider when working with Oracle

     Try
        myConnection.Open()


        myConnection.Close()
    Catch ee As Exception
    End Try

End Sub

End Module
