ASP.NET boolean variable

Question

I've been looking at some source code for an ASP.NET page and stumbled across

booLockAll=(booLockAll==false);

I've never seen a variable declared like this in any other language.
Is this unique for ASP.NET?
Is this just wrong?

Why would you not write it: booLockAll==false

Can you give us a little more context, is this in the code behind file? Where is booLockAll defined (there's no bool or var there) — Liath

This is not a declaration. It's an assignment statement whose effect is inverting the variable's value.

booLockAll is false => (booLockAll==false) yields true
booLockAll is true  => (booLockAll==false) yields false

Easier and a lot more readable would be to use booLockAll = !booLockAll;.

That's just invert of a bool variable, just like

booLockAll = !booLockAll

The code is used to change the value of booLockAll.

Sample code that does the same

if(booLockAll==false)
{
   booLockAll = true;
}
else
{
   booLockAll = true;
}

That means if previous value of booLockAll was false then new value will be true or if previous one was true then new one will be false.
