给出一些对象列表:
List<Car> carlist = new List<Car>();
如何将此列表序列化为XML或二进制文件并将其反序列化?
到目前为止,我有这个,但它不起作用.
//IsolatedStorageFile isFile = IsolatedStorageFile.GetUserStoreForApplication(); //IsolatedStorageFileStream ifs = new IsolatedStorageFileStream("myxml.xml",FileMode.Create,isFile); //DataContractSerializer ser = new DataContractSerializer(); //XmlWriter writer = XmlWriter.Create(ifs); //ser.WriteObject(writer,carlist);
我正在使用这些方法从/到IsolatedStorage的XML文件中保存和加载:
public static class IsolatedStorageOperations { public static async Task Save<T>(this T obj,string file) { await Task.Run(() => { IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication(); IsolatedStorageFileStream stream = null; try { stream = storage.CreateFile(file); XmlSerializer serializer = new XmlSerializer(typeof (T)); serializer.Serialize(stream,obj); } catch (Exception) { } finally { if (stream != null) { stream.Close(); stream.Dispose(); } } }); } public static async Task<T> Load<T>(string file) { IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication(); T obj = Activator.CreateInstance<T>(); if (storage.FileExists(file)) { IsolatedStorageFileStream stream = null; try { stream = storage.OpenFile(file,FileMode.Open); XmlSerializer serializer = new XmlSerializer(typeof (T)); obj = (T) serializer.Deserialize(stream); } catch (Exception) { } finally { if (stream != null) { stream.Close(); stream.Dispose(); } } return obj; } await obj.Save(file); return obj; } }
此外,您可以根据需要调整Load方法,在我的情况下,我尝试从文件加载,如果不存在,则创建默认值并根据构造函数放置提供的类型的默认序列化对象.
更新:
假设你有这样的汽车列表:
列表与LT;汽车> carlist = new List< Car>();
要保存,您可以将它们称为await carlist.Save(“myXML.xml”);,因为它是异步任务(异步).
要加载,var MyCars = await IsolatedStorageOperations.Load<列表与LT;车> >( “myXML.xml”). (我想,到目前为止,我没有像这样使用它作为列表...
