Arrays passed by reference or by value

Question

Are arrays or lists passed by default by reference in c#?

I have read some contradicting posts on here about C# and whether arrays are passed by value or by reference. Could someone clarify whether C# arrays are passed by value or by reference?

Thanks

The reference to the array is passed by value. This is the source of the confusion :-)

When you change elements inside array, inside a function it will affect array outside of that function but it not means that it is passed by reference by default :).
