How can I get this request structure via .asmx web service?

<methodOne>
    <myValue>string</myValue>
    <myDemoGroup>
        <myDemoGroupItem>string</myDemoGroupItem>
        <myDemoGroupItem2>string</myDemoGroupItem2>
    </myDemoGroup>
    <myComplexGroup>
        <mySubStructure>
            <subItem1>string</subItem1>
            <subItem2>string</subItem2>
        </mySubStructure>
    </myComplexGroup
</methodOne>

[Web Method]
public void MyWebMethod(MyWebMethodRequest methodOne)
{
    //Do my stuff
}

public class MyWebMethodRequest
{
    public string myValue {get; set;}
    public MyDemoGroupInfo myDemoGroup {get; set;}
}

public class MyDemoGroupInfo
{
    public string myDemoGroupItem {get; set;}
    public string myDemoGroupItem2 {get; set;}
}

public class MyComplexGroupInfo
{
    public List<MySubStructureInfo> mySubStructure {get; set;}
}

public class MySubStructureInfo
{
    public string subItem1 {get; set;}
    public string subItem2 {get; set;}
}
