Parameters
- xmlFunctionNode
Type: System.Xml.XmlElement
[in] An XmlElement object representing the expansion function definition.
- fieldName
Type: System.String
[in] The name of the variable or field this expansion function represents.
Return Value
Type: Microsoft.VisualStudio.TextManager.Interop.IVsExpansionFunction
If successful, returns an IVsExpansionFunction object; otherwise, returns a null value indicating no expansion function was found in the specified XML node.
Remarks
This method is called from Visual Studio while parsing a code snippet template file.
The base method parses any arguments from the text contained in the expansion function XML template node and then calls the CreateExpansionFunction method in the LanguageService class to create an ExpansionFunction object. The field name and argument list are set in the ExpansionFunction object and the object is returned as an IVsExpansionFunction object. If there was any problem parsing the expansion function, the base method returns nulla null reference (Nothing in Visual Basic). The base method assumes the expansion function is defined according to the code snippet schema (as described specifically in the Function Element (IntelliSense Code Snippets) reference).
