OLEDB连接到Access数据库(accdb)

我想为一个练习做一个简单的应用程序,所以连接到像Access这样的简单数据库(.accdb)会很不错

我的程序看起来像这样:

using System;
using System.Collections.Generic; 
using System.Data;
using System.Data.OleDb;
using System.Linq;
using System.Web;

namespace myProject.Account
{
    public class DbManager
    {
       private OleDbConnection _dbConnection;

       public void OpenDbConnection()
       {
        _dbConnection = new OleDbConnection {ConnectionString = GetConnectionString()};
       }

       private string GetConnectionString()
       {
        return "Provider=Microsoft.ACE.OLEDB.14.0;Data Source=exercise1.accdb";
       }

       public void CloseDbConnection()
       {
        _dbConnection.Close();
       }

       public void GetUser()
       {
        DataSet myDataSet = new DataSet();
        var myAdapptor = new OleDbDataAdapter();
        OleDbCommand command = new OleDbCommand("SELECT * FROM tblUser", _dbConnection);
        myAdapptor.SelectCommand = command;
        myAdapptor.Fill(myDataSet, "tblUser");
       } 

    }
  }

我使用Visual Studio 2010.当我使用内置调试模式"Start without Debugging"(CTRL + F5)测试我的应用程序时,我收到此错误:

"Microsoft.ACE.OLEDB.14.0"提供程序未在本地计算机上注册.

我曾尝试从Microsoft omepage下载并安装"Microsoft Access Database Engine 2010 Redistributable"(64位):http://www.microsoft.com/download/en/details.aspx？id = 13255

不幸的是,它没有解决问题.执行myAdapptor.Fill()时仍然出现错误.怎么了？

您需要Access 2007 Runtime.
