请教!VB6.0代码翻译为vb.net代码，谢谢

引用 Microsoft DAO 3.6 Object Library

Public Function DaoOpenDB(ByVal pDbType As String, ByVal pDbName As String, ByVal pMdbCnct As String) As Integer

On Error GoTo Err_Handler

Dim m_DbDataBase As DAO.Database

Dim gwsMainworkSpace As DAO.Workspace

Dim DAODBEngine As New DAO.DBEngine()

Dim m_DbWkSpace = DAODBEngine.CreateWorkspace("", " Admin ", "")

If pDbType = "c_ACCESS" Then

'Access

m_DbDataBase = m_DbWkSpace.OpenDatabase(pDbName)

Else

'Oracle

m_DbDataBase = m_DbWkSpace.OpenDatabase(pDbName, True, False, pMdbCnct)

End If

DaoOpenDB = c_OK '你在全局中已定义

Exit Function

Err_Handler:

DaoOpenDB = c_NG '你在全局中已定义

MsgBox(Err.Description, MsgBoxStyle.OkOnly + MsgBoxStyle.Critical, "Err")

End Function

vb代码翻译成vb.net代码

打开VS2005及以上版本，新建一个VB.NET语言的项目，然后点工具-升级VB6代码，把代码粘贴进去即可

请教这段VB6.0代码翻译为vb.net代码，谢谢
