如何用access数据库在C#编程中修复和创建日志

using System;
using System.Data.OleDb;

public class AccessLogHelper
{
    private string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\path\to\your\database.mdb";

    public void CreateLogTable()
    {
        using (OleDbConnection conn = new OleDbConnection(connectionString))
        {
            conn.Open();
            string sql = @"
                CREATE TABLE Log (
                    LogID AUTOINCREMENT PRIMARY KEY,
                    EventType TEXT(50),
                    EventDescription TEXT(255),
                    EventTime DATETIME
                )
            ";
            using (OleDbCommand cmd = new OleDbCommand(sql, conn))
            {
                cmd.ExecuteNonQuery();
            }
        }
    }
}

public void LogEvent(string eventType, string eventDescription)
{
    using (OleDbConnection conn = new OleDbConnection(connectionString))
    {
        conn.Open();
        string sql = @"
            INSERT INTO Log (EventType, EventDescription, EventTime)
            VALUES (?, ?, Now())
        ";
        using (OleDbCommand cmd = new OleDbCommand(sql, conn))
        {
            cmd.Parameters.AddWithValue("EventType", eventType);
            cmd.Parameters.AddWithValue("EventDescription", eventDescription);
            cmd.ExecuteNonQuery();
        }
    }
}
