问题描述

我尝试通过C＃连接到数据库，但我收到一个非常无益的错误消息，当这样做：

I'm trying to connect to a database via C#, but I'm getting a very unhelpful error message when I do so:

08:44： 17：错误：无法初始化OLE
08:44:17：错误：无法初始化OLE

"08:44:17: Error: Cannot initialize OLE08:44:17: Error: Cannot initialize OLE"

我试图寻找一个解决方案， ve不成功。我也尝试重新启动我的电脑，这也没有帮助。

I've tried looking for a solution, but I've been unsuccessful. I also tried restarting my computer, which didn't help either.

我正在运行SQL Server 2008，这里是相关的数据库代码：

I am running SQL Server 2008, and here is the relevant database code:

/// <summary>
    /// Connects to a given database and returns the database connection.
    /// </summary>
    /// <param name="file">The database file name.</param>
    /// <returns>The database connection.</returns>
    public static SqlConnection ConnectToDb(string file)
    {
        //initialize generic path
        string path = System.Reflection.Assembly.GetExecutingAssembly().Location;
        path = path.Replace("bin\\Debug\\MediaPlayer.exe", "");
        path += "Database.mdf";

        string connectionPath = @"Data Source=.\SQLEXPRESS;AttachDbFilename=" + path + ";Integrated Security=True;User Instance=True";
        SqlConnection connection = new SqlConnection(connectionPath);
        return connection;
    }

    /// <summary>
    /// Executes a SQL query in a given database.
    /// </summary>
    /// <param name="file">The database file name.</param>
    /// <param name="query">The SQL query to execute.</param>
    public static void ExecuteQuery(string file, string query)
    {

        SqlConnection connection = ConnectToDb(file);
        connection.Open();
        SqlCommand command = new SqlCommand(query, connection);
        command.ExecuteNonQuery();
        connection.Close();
    }

这是我用于几个项目的数据库代码，

This is database code that I have used for several project, and it has always worked before.

在ExecuteQuery方法的connection.Open（）行中调用错误（我知道这是因为我注释掉了其他行）。

The error is called (I know this because I commented out other lines) on the connection.Open() line in the ExecuteQuery method.

任何帮助/建议都将非常感谢：）。

Any help/advice would be greatly appreciated :).

编辑：我测试了我的数据库连接，，我只是不明白为什么我不能通过代码连接。

I tested my connection to the database and everything checked out, I just don't understand why I can't connect via code.
