C# difference between == and Equals()

I have a condition in a silverlight application that compares 2 strings, for some reason when I use

==
it returns false while
.Equals()
returns true.

Here is the code:

if (((ListBoxItem)lstBaseMenu.SelectedItem).Content.Equals("Energy Attack"))
{
// Execute code
}

if (((ListBoxItem)lstBaseMenu.SelectedItem).Content == "Energy Attack")
{
// Execute code
}


Any reason as to why this is happening?

Answer

When == is used on an expression of type object, it'll resolve to System.Object.ReferenceEquals.

Equals is just a virtual method and behaves as such, so the overridden version will be used (which, for string type compares the contents).
