Hi,

I want to create a xml as given below.

XML

<Root> <CustomerDetail> <Customer> <Id>CUST0001</Id> <Name>Jackson</Name> <Address>12th Street</Address> </Customer> <Customer> <Id>CUST0002</Id> <Name>Johnson</Name> <Address>15th Main Road</Address> </Customer> </CustomerDetail> <OrderDetail> <Placed> <Order> <CustomerId>CUST0001</CustomerId> <OrderId>ORDER0012345</OrderId> <Total>1000</Total> <Item> <ItemId>ITEM00025</ItemId> <Price>255</Price> </Item> <Item> <ItemId>ITEM00026</ItemId> <Price>745</Price> </Item> </Order> <Order> <CustomerId>CUST0002</CustomerId> <OrderId>ORDER0012346</OrderId> <Total>450</Total> <Item> <ItemId>ITEM00095</ItemId> <Price>450</Price> </Item> </Order> </Placed> <Delivered> <Order> <OrderId>ORDER0012385</OrderId> <Total>800</Total> </Order> <Order> <OrderId>ORDER0012305</OrderId> <Total>550</Total> </Order> </Delivered> <Removed> <Order> <OrderId>ORDER0012300</OrderId> </Order> <Order> <OrderId>ORDER0012301</OrderId> </Order> </Removed> </OrderDetail> </Root>

I planed to send as a class object like

C#

public class Report { public Report() { } public int CustId; public string name; public string address; public int OrderId; public int total; public int ItemId; public int price; public string operation;//Placed, Removed, Delivered }

Convert the above class objects into the xml of format mentioned in top.

Please help me to achieve it.

Thanks in advance..

Why LINQ, why lambda? Do you know about LINQ and lambda anything except their names?

Do you have answer for the question..?

I don't think it's a valid answer. I do know what to do with XML, of course. The question is if you really want to keep this schema and why, or you want to do something really robust...
