c# serialising xml (error when initializing values to class object)

Question

I am using Silverlight

I have an error on intialising the object which is:

Error   1   Duplicate initialization of member 'Parameter'  C:\Users\SHEK\Documents\Visual Studio 2012\Projects\SliderLastTry\SliderLastTry\ControlClass.cs 24  17  SliderLastTry

and it corresponds to second intialistion of Parameter:

Parameter = { new Parameter { Name = "Name2", Label = "Label2", Unit = "Uint2", Component = { new Component { Type = "Type2", Attributes = { new Attributes { Type = "Slider", Displayed = "52", Selected = "05", Items = { "20", "21", "22", "23", "24" } } } } } } }

I am trying to assign the intialise the object in Main function like this:

                Parameter = { new Parameter { Name = "Name1", Label = "Label1", Unit = "Uint1", Component = { new Component { Type = "Type1", Attributes = { new Attributes { Type = "Combo", Displayed = "42", Selected = "02", Items = { "10", "11", "12", "13", "14" } } } } } } }
            ,
                Separator = { new Separator { Separators = "AutoSkew1" } }
                ,
                Parameter = { new Parameter { Name = "Name2", Label = "Label2", Unit = "Uint2", Component = { new Component { Type = "Type2", Attributes = { new Attributes { Type = "Slider", Displayed = "52", Selected = "05", Items = { "20", "21", "22", "23", "24" } } } } } } }

and

         var memory = new MemoryStream();
         var serial = new XmlSerializer(objectToSerialize.GetType());
         serial.Serialize(memory, objectToSerialize);  
        var utf8 = new UTF8Encoding();
        return utf8.GetString(memory.GetBuffer(), 0, (int)memory.Length);

I know the reason why i have this error. But the reason for doing like this even after being aware of it is:

(1) I have to display the xml in the same order as i have shown you. I mean Parameter then Separator an then again Parameter. But if i do intialize my object in the first intialization like Parameter = { new Parameter{..} , new Parameter{..}} then it show next just after the but i want <separator>Auto Skewing</separator> between these two .

How to do solve these 2 problems ? Please do not hesitate to ask me more if you still dont understand what i am tryin to do. Thanks a lot.

EDIT: I guess it can be done through XElement but how to manage the code for that i am still not able to understand.

1: XmlSerializer does not support that scenario. To construct xml in that format, you should consider using XElement or XmlDocument instead of XmlSerializer.

2: [XmlText], but "1" makes this moot

Thanks for the answer but Why Question 1 makes you moot ?

Marc Gravell Over a year ago

@user234839 because getting XmlSerializer to do one thing, when it doesn't support the other at all, isn't helpful. If you switch to XmlDocument or XDocument/XElement, 2 no longer applies.

And is it supported by silverlight5 ? and does it support the xml formatting ? because i have to display idented(well structured, Not ina continous single line) display .It would be my next step after this.

@user silverlight. IIRC the default behaviour of Save(...) is to output indented, with options to do other things - but it should take only minutes for you to investigate this.

Thanks (I asked you in adavance because like xmlElement if i do all and at last i know that it dont format then it waste lot of work and time as well to restart with new way). Could you please give me a very small sample Because i am not able to underdqtnd how to manage the different classes that i have to create xml. Because i had [XmlRoot(ElementName = "parameters")] for root class [XmlElement("parameter")] for elements and [XmlArray("items")] [XmlArrayItem("item", typeof(string))] for arrays.
