Is there an equivilent to VB.NET ByVal?

[John Galt]

I was looking at a VB.NET program that is passing strings to method calls
using ByVal. I was wondering if this is for a reason and, if so, should a C#
conversion of code samples from VB.NET also use an equivilent rather than
passing strings by reference?

The default parameter passing in C# is 'ByVal' as well - it's just there is
no keyword for it. ByVal means that a copy of the *reference* is passed.
Never is a copy of the object passed for reference types.

Everything is passed by value in C# unless you specify otherwise. For
strings, this means the string reference is passed by value, because
string is a reference type.
