VBC编译时问题，请高手帮帮我！急，在线等

[zhanzujiejx]

在.vb中我imports的有
Imports System
Imports System.Data
Imports System.Data.OleDb
Imports System.Web.UI



Namespace BannanaMobile
Public Class Userdetails
Public UserID As Integer
Public Username As String
Public Password As String
Public FirstName As String
Public LastName As String
Public City As String
Public State As String
Public Zip As String
Public Address As String
Public Phone As String
Public Email As String

End Class

Public Class User
Private objConn As New OleDbConnection("provider=Microsoft.jet.oledb.4.0;data source=c:\banana.mdb")
Public Function Login(ByVal strUsername As String, ByVal strPassword As String) As Integer
Dim intId As Integer
Dim objCmd As New OleDbCommand("sqLoginUser", objConn)
objCmd.CommandType = CommandType.StoredProcedure
Dim objParam As New OleDbParameter("@Username", OleDbType.Char)
objParam.Value() = strUsername
objCmd.Parameters.Add(objParam)



End Function

End Class
End Namespace

然后我使用vbc编译时命令为：
C:\WINNT\Microsoft.NET\Framework\v1.0.3705>vbc /target:library /out:user.dll user.vb
但运行后出现如何错误：

C:\WINNT\Microsoft.NET\Framework\v1.0.3705\User.vb(2) : error BC30466: 无法找到
Imports“System.Data”的命名空间或类型“Data”。

Dim objParam As New OleDbParameter("@Username", OleDbType.Char).......
其他的象很多函数都不提示未声明。

请问高手到底应该如何解决？
