C# Soap Client producing Null Pointer Exception

I am writing a simple C# SOAP client to send an API request but I am receiving a NullPointerException when trying to send a value which looks like it is on a different 'level' of the API request.

I have written the following code to create an instance of the API request:

CreateOrderRequest createOrder = new CreateOrderRequest();

When using SOAP UI ,the XML request contains the following extract:

<data:ProductCode>RX888</data:ProductCode>
 <data:Orders>
               <!--Zero or more repetitions:-->
               <data:OrderLine>
                  <!--Optional:-->
                  <data:OrderAmount>157.65</data:OrderAmount>
                  <data:OrderRef>test</data:OrderRef>
               </data:OrderLine>
</data:Orders>

In my code, I can specify a value to use for the product code by writing the following:

createOrder.ProductCode = "RX888";

When I try to specify a value for the OrderAmount I get a nullpointer exception if I do `createOrder.OrderAmount = "5.99";

I get the same if I try to specify a value for the OrderRef too.

Can anybody help me to get this to work please?!

Based on your xml, it seems there is no createOrder.OrderAmount.

Your xml seems to indicate that you want to set createOrder.OrderLine[n].OrderAmount, where n is the item in your List(?) of OrderLine.

Since you are getting a NRE, the simplest explanation is that you never instantiated your List, which means it's null.

Adding this to the constructor of your CreateOrderRequest should help:

this.OrderLines = new List<OrderLine>();

Of course, adjust this for your actual definition in your CreateOrderRequest
