c# : XmlSerialzier problem
Hello,
I have following structs public struct User { public string Username; public string Password; public string[] Permissions; } public struct Users { public User[] RemoteUsers; } when I Serialize a Users struct I get following File <?xml version="1.0" encoding="utf-8" ?> <Users xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <RemoteUsers> <User> <Username>Admin</Username> <Password>21232F297A57A5A743894A0E4A801FC3</Password> <Permissions> <string>All</string> </Permissions> </User> </RemoteUsers> </Users> all is OK I think.. but when I deserialize it using Users users = (Users)serializer.Deserialize(streamReader)); I get following error: Error in XML-document (2,2). at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle) at System.Xml.Serialization.XmlSerializer.Deserialize(TextReader textReader) at Remote.Users.UserControl.LoadUsers()
Don't you need to put the [Serializable] attribute in front of (at least)
Users? José "Dirk Reske" <_Freak.2k@gmx.net> a écrit dans le message de news:eVDMqvj0DHA.2752@TK2MSFTNGP09.phx.gbl...

No it doesn't work.
But, when I serialize the structure, all works fine. I get this error only at deserializing....

BTW, is there any reason why you use XML Serialization instead of SOAP
serialization (using the SOAP formatter)? I gave a try with the soap one and all is fine José "Dirk Reske" <_Freak.2k@gmx.net> a écrit dans le message de news:O10IFBk0DHA.1708@TK2MSFTNGP12.phx.gbl...

I don't know how soap works....I never used it...
can you post some example? "José Joye" <jose.joye@__No_SPam__bluewin__maPS_oN__.ch> schrieb im Newsbeitrag news:OQLQQZk0DHA.716@TK2MSFTNGP12.phx.gbl...

Here is a small sample that relates to your code:
José using System; using System.IO; using System.Runtime.Serialization.Formatters.Soap; namespace ConsoleApplication7 { [Serializable] public struct User { public string Username; public string Password; public string[] Permissions; } [Serializable] public struct Users { public User[] RemoteUsers; } /// <summary> /// Summary description for Class1. /// </summary> class Class1 { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main(string[] args) { FileStream myStream = File.Create("test.xml"); SoapFormatter myXMLFormat = new SoapFormatter(); User u1; u1.Password = "abc"; u1.Username = "ABC"; string[] perms = new string[2]; perms[0] = "all"; u1.Permissions = perms; Users users; users.RemoteUsers = new User[1]; users.RemoteUsers[0] = u1; myXMLFormat.Serialize(myStream, users); myStream.Close(); myStream = File.OpenRead("test.xml"); Users userRead = (Users)myXMLFormat.Deserialize(myStream); Console.ReadLine(); } } } "Dirk Reske" <_Freak.2k@gmx.net> a écrit dans le message de news:O0OV$nk0DHA.2308@TK2MSFTNGP11.phx.gbl...

Hello,
thanks to all, but I find the mistake myself. I serialize a "Users" struct but tried to deserialize a "User" struct "Frans Bouma" <perseus.usenetNOSPAM@xs4all.nl> schrieb im Newsbeitrag news:Xns946699A2F800perseusnewsxs4allnl@207.46.248.16...
