I read on a site that you cannot pass arrays ByVal. Is this true?

No, that is not true.

An array in the .NET framework is a reference type. When you create an array, an object of System.Array will be created and its reference is assigned to the reference variable.

When you call a des method, the reference of the array object will be passed. In des method, ByVal parameter is a reference parameter variable of type System.Array, and it receive a copy of reference of an array object.
