c#XML序列化與反序列化

C#XML序列化與反序列化很不爽,只能改成了BinaryWriter和BinaryReader來(lái)讀寫(xiě),突然想到能不能用XML來(lái)序列化?于是在網(wǎng)上查了些資料便寫(xiě)了些實(shí)踐性代碼,做些記錄,避免以后忘記。序列化對(duì)象publicclassPeople[XmlAttribute(nNAMEn)]publicstringName{set;get;}[XmlAttribute(nAGEn)]publicintAge{set;get;}[XmlRoot(nRootn)]publicclassStudent:People[XmlElement(nCLASSn)]publicstringClass{set;get;}[XmlElement(nNUMBERn)]publicintNumber{set;get;}voidMain(string[]args)Studentstu=newStudent()r\〇Class二''ClassOne"Name=''Tom"Number=1XmlSerializerser=newXmlSerializer(typeof(Student));ser.Serialize(File.Create(HC:\\x.xml

這個(gè)字段作為xml的屬性,屬性

名跟在グ‘中[XmlElement("Value")]意思是將這個(gè)字段做為xml的元素。反序列化DirctionaryXmlSerializerser二new

Deserialize反序列化。真希望.Net

能集成Dirctionaryv＞對(duì)象,那我們這些懶人就方便了。在需要序列化的隊(duì)伍中，數(shù)組是很常見(jiàn)的類(lèi)型,其次就是圖片了序列化圖片publicstructImageStruct[XmlAttribute(''Numbern)]publicintnumber;[XmlElement(ffImageff)]publicbyte[]picture;voidMain(string[]args)ImageStruct(){number=1,

這里我還加了個(gè)圖片的名字,到

penRead(nc:\\x.xmln));pictureBox1.Image二Image.FromStream(newMemoryStream(s.picture));memorystream來(lái)做緩存,這樣會(huì)比較快ー點(diǎn),實(shí)際上我并沒(méi)有怎么感覺(jué)。圖片數(shù)組序列化publicstructImageStruct[XmlAttribute(''Numbern)]publicintnumber;[XmlElement(ffImageff)]publicbyte[]picture;voidMain(string[]args)List<ImageStruct>imageList=newList<ImageStruet>();imageList.Add(newImageStruct()number=1,picture=File.ReadAllBytes(@”11.jpg”)?cimageList.Add(newImageStruct()picture=File.ReadAllBytes(@n22.jpgn)?cXmlSerializerser二new
