如何将答案选择保存到access数据库c#

string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=path\\to\\your\\database.accdb";
using (OleDbConnection connection = new OleDbConnection(connectionString))
{
    connection.Open();
    // 执行数据库操作
}

string sql = "INSERT INTO TableName (Column1, Column2) VALUES (@Value1, @Value2)";
using (OleDbCommand command = new OleDbCommand(sql, connection))
{
    // 添加参数并设置值
    command.Parameters.AddWithValue("@Value1", value1);
    command.Parameters.AddWithValue("@Value2", value2);
    
    // 执行插入操作
    command.ExecuteNonQuery();
}

string sql = "SELECT * FROM TableName";
using (OleDbCommand command = new OleDbCommand(sql, connection))
{
    using (OleDbDataReader reader = command.ExecuteReader())
    {
        while (reader.Read())
        {
            // 读取数据并进行处理
            string column1Value = reader.GetString(0);
            string column2Value = reader.GetString(1);
            // ...
        }
    }
}

connection.Close();
