Version: 1 | Requires: CF7 | Library: DataManipulationLib

Description:
Originally written by Joe Reinhart, so give him the credit. I just found this function useful and fixed a bug so it could be submitted. It will take a .Net Dataset and convert it to a CF structure of queries.

Return Values:
Returns a structure.

Example:

<cfinvoke webservice="http://www.example.com/query.asmx?WSDL" method="NameSearch" returnvariable="data">
	<cfinvokeargument name="LastName" value="xxxx"/>
	<cfinvokeargument name="FirstName" value="xxxx"/>
	<cfinvokeargument name="MidName" value="xxxx"/>
</cfinvoke>
<cfdump var="#convertDotNetDataset(data)#">

Parameters:

Name Description Required
dataset Dot net dataset. Yes
