Why does this compile?

[Frank Rizzo]

Maybe I don't know all the c# quirks, but the code below should be compiling, but it does.  See the bolded code at the bottom.

using System;

namespace ConsoleApplication19
{
    class Class1
    {
        [STAThread]
        static void Main(string[] args)
        {
            Child child = new Child();
            Console.WriteLine(child.SomeVariable.ToString());
        }
    }

    public class MyBase
    {
        public int SomeVariable;
    }

    public class Child : MyBase
    {
        public Child()
        {
            base.SomeVariable = 1;
            
            // why in the world does this compile???
            // note the space between the base and .SomeVariable
            base .SomeVariable = 2;    
        }
    }
}

I don't know, as you posted HTML in a text newsgroup. Please repost you
question in a format appropriate to the forum.

Thank you.

Frank,

There is nothing in the specification that says that the period has to
come as the character right after the expression and before the
property/method. You can have as many spaces as you want.

Hope this helps.

Er.....who cares? The fact is it does, at a guess the compiler reads the
line and looks for the next character finds a '.' reads it as a combined
line and sees no issues.

i cant believe you are wasting your own time posting this and anybody elses
to ask such a question?

Sorry. I was having line overruns, which is why I posted it in html.
Here is the fixed up version.

using System;

namespace ConsoleApplication19
{
class Class1
{
[STAThread]
static void Main(string[] args)
{
Child child = new Child();
Console.WriteLine(child.SomeVariable.ToString());
}
}

public class MyBase
{
public int SomeVariable;
}

public class Child : MyBase
{
public Child()
{
base.SomeVariable = 1;

// why in the world does this compile???
// note the space between the base and .SomeVariable
base .SomeVariable = 2;
}
}
}

 

[Mark Rae]

base.SomeVariable = 1;

// why in the world does this compile???
// note the space between the base and .SomeVariable
base .SomeVariable = 2;

Why wouldn't it compile? Are you attributing some mystical significance to
the white space...?

Because C# certainly doesn't...

Whitespace like that is fine. It's not uncommon to see:

x.DoSomething()
.DoSomethingElse()
.AndSomethingElse()

In particular, that's often seen with strings:

x = x.Trim()
.Replace ("\r", "\\r")
.Replace ("\n", "\\n");

This doesn't compile on my box.

This does.

Never mind, I misunderstood you. It, of course, compiles just fine.

That's a bit snide. Any developer who didn't know that may be saved
time debugging someone elses code who did know it just by reading this
thread. Second any curiosity is good and should be encouraged. Third,
this works in C# but not in VB.net so for anyone converting from one to
the other, it would be confusing.
If I had to recruit either you or the OP I'd go with the OP simply
because he's curious and seeks a deeper understanding of his subject
which will serve him well in the future.

I can't believe you are wasting your own time and everybody elses
answering such a dumb question.

i totally agree. i know that's what we look for.
