Get Controller's Action name in View

What is the correct way to get the name of the Action returning the View in MVC3?

I am using ViewContext.Controller.ValueProvider.GetValue("action").RawValue to return the name of the Action (Method), which is creating the View in MVC3. I return this in a Partial View, which is included in the View returned by the Action.

It works fine for Index, but, when I try to use it for another method name, it always evaluates to false.

In the immediate window I get the following results:

ViewContext.Controller.ValueProvider.GetValue("action").RawValue
"Edit"

ViewContext.Controller.ValueProvider.GetValue("action").RawValue == "Edit"
false

Which is highly confusing, because the first statement evaluates to a string with value "Edit", while comparing this to a string "Edit" returns false?

Bizarre...
