Xml serialization - Hide null values

When using a standard .NET Xml Serializer, is there any way I can hide all null values? The below is an example of the output of my class. I don't want to output the nullable integers if they are set to null.

Current Xml output:

<?xml version="1.0" encoding="utf-8"?>
<myClass>
   <myNullableInt p2:nil="true" xmlns:p2="http://www.w3.org/2001/XMLSchema-instance" />
   <myOtherInt>-1</myOtherInt>
</myClass>

What I want:

<?xml version="1.0" encoding="utf-8"?>
<myClass>
   <myOtherInt>-1</myOtherInt>
</myClass>
