Can I pass a new bool as a reference?

[Danja91]

I have a quick question about how to condense two lines into one.

The following code works:

bool pass = false;
MyFunction(ref pass);

I would like to turn it into the following:

MyFunction(ref new bool(false))

But that doesn't work in the compiler. Is there a correct syntax for this?

The compiler error says it all - "a 'ref' or 'out' argument must be an assignable variable".

That's a little bit annoying. In that case, could you tell me if there's a better way to execute the following?

int main()
        {
            List<string> results = new List<string>();
            Console.WriteLine("Press ESC to skip the current drive");
            for (char i = 'A'; i <= 'Z'; i++)
            {
                string search = i + ":\\";
                Console.WriteLine("Searching through drive {0}", search);
                Console.SetCursorPosition(0, Console.CursorTop - 1); // replace previous statement
                bool ESCnow = false;
                results = search("searchforthis", ref ESCnow);
            }
        }

List<string> search(string searchstring, ref breaknow)
{
    if (Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.Escape) { breaknow = true; }
    if (breaknow == true) { return; }

    // execute my specialized search statements here
    DirectoryInfo NewDirInf = new DirectoryInfo(Directory.GetCurrentDirectory());
    foreach (DirectoryInfo SubDirInf in NewDirInf)
    {
          search (searchstring, ref breaknow);
    }
}

Is there a better way to break out of the search function than via the ref bool?

[David Anton]

After each call to 'search', I would add:
if (breaknow)
break;
