Serialization problem

[Yoyosh 0]

Sure, this is class, which object`s are kept in array/arraylist: [Serializable] public class DataGridRow { public int Time; public float Speed; public DataGridRow(int t, float s) { Time = t; Speed = s; } public DataGridRow() { } } And this is part of other class, that performs serialization: /// /// Keeps objects of type DataGridRow /// ArrayList RouteData = new ArrayList(); (...) public void Serialize() { DataGridRow[] dgr = new DataGridRow[RouteData.Count]; for (int i = 0; i < RouteData.Count; i++) { dgr[i] = (DataGridRow)RouteData[i]; } XmlSerializer a = new XmlSerializer(dgr.GetType()); StreamWriter sw = new StreamWriter(@"c:/aaa.txt"); a.Serialize(sw, RouteData); } Please let me know if I missed something (I may send it to you if you like)

OK, After going through the above code what i think is that when u are serializing u have to fetch each item from the Arraylist and serialize each object which is of the class DataGridRow, and also mention the class name in the XML Serializer constructor. Also change the file type i.e. c:\aaa.xml Try the above changes, if it works well and good if not just repost the error that u get and send the project so that we can debug and check what's going wrong.

At begin I wanted to serialize the ArrayList with all elements included. Then some guy told me, that ArrayList objects can`t be serialized, but I`m sure that 1D arrays are. So thats why I copied all elements from ArrayList to Array of type DataGridRow. So I don`t think there is a must to serialize each object separately... I changed file name to aaa.xml, still I get the same error. Here you can download this whole project (112kb) thank you very much for help

ok what i had done is i created a class declared that serializable, declared the properties and wrote a method which was used to set values to the properties and also wrote the serialize method in the same class and then in the serialize method i used this object to serialize. The link that u have sent is blank and i could not find any project there.

one important thing that u have forgot is you have to declare the class as [XMLRoot "classname"] and the properties as [XMLElement "name"] try this

I added these attributes - still the same result :( The link was correct, I tested it, but maybe server was down at the time you tried it. Nevertheless - this is the same project on another server: Download (I tested it and it worked) Or, if you still develope some problems with downloading, please supply mi with your @mail address again, thank you very much for helping
