Question

我有一个由GridView填充的下面定义的列表。一切都很好。

将此列表保存/加载到文件中的最佳方法是什么（XML或其他方式可以）？

注意：将来我会加密文件。

C＃代码

List<Item> lstNewItems = new List<Item>(); // Control Items  
lstNewItems.Clear();

foreach (GridViewRow PendingItemUnderControl in GridViewPendingList.Rows)
{
    Item NewItem = new Item();
    NewItem.Paramater = PendingItemUnderControl.Cells[0].Text.ToLower();
    NewItem.Type = (String)Session["BrowseType"];
    lstNewItems.Add(NewItem);
}

public class Item
{
    public Item(string Paramater, string Type)
    {         
        _Paramater = Paramater;
        _Type = Type;
    }
    private string _Paramater;
    [DataMember]
    public string Paramater
    {
        get { return _Paramater; }
        set { _Paramater = value; }
    }
    private string _Type;
    [DataMember]
    public string Type
    {
        get { return _Type; }
        set { _Type = value; }
    }
}

Answer 1

ProtoBuf Net是二进制序列化程序，但它非常灵活和快速

Answer 2

对于结构化数据，XML或非常轻量级的SQL RDBMS（如SQLite或SQL Server Compact Edition）都可以正常运行

我建议XML读取器/编写器类用于文件，因为它很容易序列化序列化是一种将对象转换为二进制表示的简单方法，然后可以将其写入磁盘或通过网络发送。

解决方案C＃代码

#region Save the object

            // Create a new XmlSerializer instance with the type of the test class
            XmlSerializer SerializerObj = new XmlSerializer(typeof(List<Item>));

            // Create a new file stream to write the serialized object to a file
            TextWriter WriteFileStream = new StreamWriter(@"C:\test.xml");
            SerializerObj.Serialize(WriteFileStream, lstNewItems);

            // Cleanup
            WriteFileStream.Close();

            #endregion

            // Load items to control
            #region Load the object

            // Create a new file stream for reading the XML file
            FileStream ReadFileStream = new FileStream(@"C:\test.xml", FileMode.Open, FileAccess.Read, FileShare.Read);

            // Load the object saved above by using the Deserialize function
            List<Item> LoadedObj = (List<Item>)SerializerObj.Deserialize(ReadFileStream);

            // Cleanup
            ReadFileStream.Close();

            #endregion

            // Load up all the settings

            for (int i = 0; i < LoadedObj.Count; i++) // Loop through List with for
            {
                String ThisisAnItemToControl = LoadedObj[i].Paramater;
                String ThisIsItsType = LoadedObj[i].Type;
            }
