C # serialization and deserialization

Using system. io; using system. runtime. serialization. formatters. binary; using system. runtime. serialization. formatters. soap; using system. XML. serialization; using system. runtime. serialization; public class serializeanddeserialize {// 1. Use binaryformatter to serialize public void serializenow () {classtoserialize c = new classtoserialize (); filestream = new filestream ("C: \ temp. dat ", filemode. create); binaryformatter B = new binaryformatter (); B. serialize (filestream, c); filestream. close ();} public void deserializenow () {classtoserialize c = new classtoserialize (); C. sex = "KKKK"; filestream = new filestream ("C: \ temp. dat ", filemode. open, fileaccess. read, fileshare. read); binaryformatter B = new binaryformatter (); C = B. deserialize (filestream) as classtoserialize; console. writeline ("output:" + C. name); console. writeline ("output:" + C. ID); console. writeline ("output:" + C. sex); filestream. close () ;}// 2. Use soapformatter to serialize public void serializenow_soap () {classtoserialize c = new classtoserialize (); filestream = new filestream ("C: \ temp2.dat ", filemode. create); soapformatter S = new soapformatter (); S. serialize (filestream, c); filestream. close ();} public void deserializenow_soap () {classtoserialize c = new classtoserialize (); C. sex = "KKKK"; filestream = new filestream ("C: \ temp2.dat", filemode. open, fileaccess. read, fileshare. read); soapformatter S = new soapformatter (); C = S. deserialize (filestream) as classtoserialize; console. writeline ("output:" + C. name); console. writeline ("output:" + C.

Use xmlserializer to serialize public void xmlserialize () {person C = new person ("CYJ"); C. courses = new course [2]; C. courses [0] = New Course ("English", "communication tools"); C. courses [1] = New Course ("Mathematics", "Natural Science"); xmlserializer xs = new xmlserializer (typeof (person); stream = new filestream ("C: \ CYJ. html ", filemode. create, fileaccess. write, fileshare. read); Xs. serialize (stream, c); stream. close ();} public void xmldeserialize () {xmlserializer xs = new xmlserializer (typeof (person); stream = new filestream ("C: \ CYJ.

Custom serialization public void otheremployeeclasstest () {employee MP = new employee (); MP. empid = 10; MP. empname = "Qiu Feng"; MP. noserialstring = "hello"; stream steam = file. open ("C: \ temp3.dat", filemode. create); binaryformatter BF = new binaryformatter (); console. writeline ("output:" + "Writing employee info:"); BF. serialize (steam, MP); steam. close (); MP = NULL; // deserialize stream steam2 = file. open ("C: \ temp3.dat", filemode. open); binaryformatter bf2 = new binaryformatter (); console. writeline ("output:" + "reading employee info:"); employee MP2 = (employee) bf2.deserialize (steam2); steam2.close (); console. writeline ("output:" + mp2.empid); console. writeline ("output:" + mp2.empname); console. writeline ("output:" + mp2.noserialstring) ;}} [serializable] public class classtoserialize {public int id = 100; Public string name = "name "; [nonserialized] Public String sex = "male";} [serializable] public class person {private string name; Public string name {get {return name ;} set {name = value ;}} Public String sex; Public int age = 31; public course [] courses; Public Person () {} public person (string name) {name = Name; Sex = "male" ;}} [serializable] public class course {public string name; [xmlignore] Public String description; Public Course () {} public course (string name, string description) {name = Name; description = description;} [serializable] public class employee: iserializable {public int empid = 100; public String empname = "Work hard work smart work happy"; [nonserialized] Public String noserialstring = "noserialstring-test"; public employee () {} private employee (serializationinfo info, streamingcontext ctxt) {empid = (INT) info. getvalue ("employeeid", typeof (INT); empname = (string) info. getvalue ("employeename", typeof (string);} public void getobjectdata (serializationinfo info, streamingcontext ctxt) {info. addvalue ("employeeid", empid); info. addvalue ("employeename", empname );}}
