如何将列表数据放到C#中的另一个位置

List<string> dataList = new List<string>();
dataList.Add("Data 1");
dataList.Add("Data 2");
dataList.Add("Data 3");

List<string> anotherList = new List<string>(dataList);

using (StreamWriter writer = new StreamWriter("data.txt"))
{
    foreach (string data in dataList)
    {
        writer.WriteLine(data);
    }
}

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    
    foreach (string data in dataList)
    {
        SqlCommand command = new SqlCommand("INSERT INTO TableName (ColumnName) VALUES (@Data)", connection);
        command.Parameters.AddWithValue("@Data", data);
        command.ExecuteNonQuery();
    }
}
