how to convert Expression<Action> to Action

Hey i was wondering if i can convert an Expression to an Action. I need to use the Expression to get the details of the lambda expression and at the same time i need to execute it using a different method. I need to get the Expression and the actual action with just using a single parameter (either Action or Expression): BTW i need this for Getting details on what kind of assert i did. ex(Assert.true, Assert.False)

public void otherMethod()
{
  SomeMethod(() => Assert.Equals("Dog","Cat"));
}



 public void SomeMethod(Expression<Action> neededAction) //or public void SomeMethod(Action neededAction)
    {       

          //i need to run the neededAction and get the details whether what assert i did and the inputs i used for the assertion

    }

So basically i need to run the Action and i need to get its method infos. Thanks~

You need to call Compile() on the expression.

// Compile it.
var actualNeededAction = neededAction.Compile();

// Execute it.
actualNeededAction();
