我正在尝试使用oledb连接,同时使用csc.exe编译器。但不知何故,代码不会在.net ide上出错,但在csc.exe上会出错。

代码:

using System;   
using System.Data.OleDb;

class vtBaglanti
{   
    static void Main()
    {
        string kaynak = "Provider=Microsoft.ACE.Oledb.12.0;Data Source=okul.accdb";

        OleDbConnection baglanti = new OleDbConnection(kaynak);    
        baglanti.Open();

        Console.WriteLine("VT Bağlantısı Sağlanmıştır.");
    }
}

错误:

错误意味着“Microsoft.ACE.OLEDB.12.0'提供程序未在本地计算机上注册。之前已经讨论过了。您需要在计算机上安装ACE组件。您需要将ACE的CPU体系结构与已安装的MS Office版本的CPU体系结构相匹配。

answer包含ACE发行版列表供您选择。

在大多数情况下,ACE的2010版本应该足够了:

Microsoft Access Database Engine 2010 Redistributable
