UseTypeEmptyTypesRule Class

This rule fires if a zero length array of System.Type is created. This value is so often required by the framework API that the System.Type includes an EmptyTypes field. Using this field avoids the memory allocation (and GC tracking) of your own array.

Syntax

[Gendarme.Framework.Solution("Use Type.EmptyTypes instead of creating your own array.")]
public class UseTypeEmptyTypesRule : Gendarme.Framework.Rule, Gendarme.Framework.IMethodRule
