During BeginInvoke calls, what does the @object parameter refer to ?

Question

Hi,

In a sample use of the BeginInvoke thread pool method:

...
Func<string, int> method = someWorkMethod;
IAsyncResult cookie = method.BeginInvoke("test", ...

One of the expected parameters (the last one), in BeginInvoke is:

object @object

What does the @ signify ?

Thanks,

Scott

Answer 1

The @ is an escape symbol that lets you use keywords as symbol names. For instance, you couldn't normally do:

object object = something;

...because object is a keyword, but you can do:

object @object = 

void DoSomething(params object[] @params) {

...etc

Answer 2

It simply an escape character. That way, you're allowed to name parameters anything you want, even if it is a reserved keyword.
