Question

您好我没有VB6或VB.NET的经验，但我正在尝试将一些旧代码转换为.NET。 VB6使用PrivDBEngine。

 Public oDbEngine As New PrivDBEngine

经过一些谷歌搜索，这看起来像DAO。有人告诉我用ADO.NET替换它的用法。我粘贴在下面的代码中我看到的每个位置作为参考，以防它有帮助。我将谷歌搜索“PrivateDBEngine DAO到ADO.NET”，但如果有人知道ADO.NET中的等价物，或者甚至有一些有用的链接，请告诉我。我应该查看DataSet吗？非常感谢你的时间和耐心。我遇到的其他地方是：

 ' Build the proper connection string.  If ODBC, the
    ' options line of the OpenDatabase method accepts the
    ' connection string.  If Access, just pass in the
    ' filename
    sPassword = Password
    Select Case ConnType
        Case DBTYPE_ACCESS
            DBFilename = ConnectString
            If (Len(UserName) = 0 And Len(Password) <> 0) Then
                DBOptions = ";PWD=" + Password
                sPassword = ""
            Else
                DBOptions = ""
            End If
            If (UserName = "") Then
                UserName = "Admin"
            Else
                UserName = UserName
            End If
            If (Len(SystemMDB) <> 0) Then
            --->  oDbEngine.SystemDB = SystemMDB <-----------
            End If

还有：

  ' Handle UserName and Password.
     Set oWorkSpace = oDbEngine.CreateWorkspace("Test", UserName, sPassword)

最后：

 Sub CleanUpDBConnection()

    On Error Resume Next

    ' Close the recordsets
     grsIndexTable.Close
     grsDocTable.Close

    ' Close the database
    If Connected Then
         DBConnection.Close
        Set DBConnection = Nothing
         oWorkSpace.Close
        Set oWorkSpace = Nothing
        Set oDbEngine = Nothing
        CurrentDTable = ""
        CurrentITable = ""
        Connected = False
    End If

End Sub

VB6中是否存在VB.NET等效的PrivateDBEngine？
