. Net (C #): differences between xmlarrayitem and xmlelement in serialized Arrays

For example, the xmlarrayitem attribute is used to indicate the element types in the array:

Public Class A

{

[ Xmlarrayitem (Type = Typeof ( Int )), Xmlarrayitem (Type = Typeof ( Guid )), Xmlarrayitem (Type = Typeof ( String )]

Public Object[] Arr= New Object[] {12,"Hehe",Guid.Newguid ()};

}

 

The serialized XML is:

<A Xmlns: xsi="Http://www.w3.org/2001/XMLSchema-instance"

Xmlns: XSD="Http://www.w3.org/2001/XMLSchema">

<Arr>

<Int>12</Int>

<String>Hehe</String>

<Guid>291b7cba-fc32-4019-bb22-d5d61643b6a7</Guid>

</Arr>

</A>

The arr field name is written as an XML element.

 

However, if you change xmlarrayitem to xmlelement:

Public Class A

{

[ Xmlelement (Type = Typeof ( Int )), Xmlelement (Type = Typeof ( Guid )), Xmlelement (Type = Typeof ( String )]

Public Object[] Arr= New Object[] {12,"Hehe",Guid.Newguid ()};

}

 

The serialized XML is as follows:

<A Xmlns: xsi="Http://www.w3.org/2001/XMLSchema-instance"

Xmlns: XSD="Http://www.w3.org/2001/XMLSchema">

<Int>12</Int>

<String>Hehe</String>

<Guid>5e7da5a0-d513-47b7-ae8f-80b404a9b0d4</Guid>

</A>

 

There is no arr field name!

Note that you can use xmlarrayitem or elementname of xmlelement to control the names of XML elements of the corresponding type.
