C++ Snippet to C# Bitwise Operators

Question

I am having a hard time porting this part of C++ to C#. I keep getting Operator '||' cannot be applied to operands of type 'long' and 'long' which makes sense. So what would the equivalent be?

    while ((c <= combinations) && ((round_set & (1 << cList[c].one)) || (round_set & (1 << cList[c].two)) || (cUsed[c])))
                   {
                   fprintf( stdout, "C: %d\n", c);
                    c++;
                    }

while ((c <= combinations) && ((round_set & (1 << cList[c].one)) || (round_set & (1 << cList[c].two)) || (cUsed[c])))
                            {
                                Console.WriteLine("C: {0}", c);

                                c++;
                            }

C++, unlike C#, lets you treat an integer value as if it were a boolean value, ad-hoc, where any integer 0 is false, and any integer other than 0 is true. C# does not allow this.

To achieve the same effect in C# you must explicitely perform the check I just described, so instead of

if( (expr) || ... ) { }

you want

if( (expr) != 0 || ... ) { }

And in fact the latter is still perfectly acceptable (and sometimes encouraged for clarity) in C++.
