Is it possible to dynamically compile and execute C# code fragments?

Checking length of dictionary object [duplicate]
...setting 0 on the object, or are you relying on custom string keys? eg obj['foo'] = 'bar';. If the latter, again, why the need for length?
Edit #1: Why can't you just do this?
list = [ {name:'john'}, {name:'bob'} ];
Then iterate over list? The length is already set.

Unpacking array into separate variables in JavaScript
...two = arr[1];
ES6 will allow destructuring assignment:
let [x, y] = ['foo', 'bar'];
console.log(x); // 'foo'
console.log(y); // 'bar'
Or, to stick to your initial example:
var arr = ['one', 'two'];
var [one, two] = arr;
You could also create a default value:
const [one = 'one', two = 'two...

How do I get an HttpContext object from HttpContextBase in ASP.NET MVC 1?
...mple illustrates how you can do this. It supposes you have a method called Foo that accepts context as HttpContextBase but then needs to call a method in a third-party assembly (that you may not have the good fortune to modify) that is expecting the context to be typed as HttpContext.
void Foo(Http...
Why use the params keyword?
... allows you to call the method with a single argument.
private static int Foo(params int[] args) {
int retVal = 0;
Array.ForEach(args, (i) => retVal += i);
return retVal;
}
i.e. Foo(1); instead of Foo(new int[] { 1 });. Can be useful for shorthand in scenarios where you might need ...
What is getattr() exactly and how do I use it?
...ethod name.
For example, you cannot do this:
obj = MyObject()
for x in ['foo', 'bar']:
obj.x()
because x is not of the type builtin, but str. However, you CAN do this:
obj = MyObject()
for x in ['foo', 'bar']:
getattr(obj, x)()
It allows you to dynamically connect with objects based o...
Why is Git better than Subversion?
...ty much the same. There isn't much difference between:
svn checkout svn://foo.com/bar bar
cd bar
# edit
svn commit -m "foo"
and
git clone git@github.com:foo/bar.git
cd bar
# edit
git commit -a -m "foo"
git push
Where Git really shines is branching and working with other people.
