How to access property of anonymous type in C#?
...
Then from that you look up a property:
PropertyInfo p = t.GetProperty("Foo");
Then from that you can get a value:
object v = p.GetValue(o, null);
This answer is long overdue for an update for C# 4:
dynamic d = o;
object v = d.Foo;
And now another alternative in C# 6:
object v = o?.GetTy...

How to default to other directory instead of home directory
...d.sh
Or you can create an alias or function in your $HOME/.bashrc file:
foo() { cd /d/work_space_for_my_company/project/code_source ; }
If the directory name includes spaces or other shell metacharacters, you'll need quotation marks; it won't hurt to add them even if they're not necessary:

C multi-line macro: do/while(0) vs scope block [duplicate]

Consider the following code sketch
if (<condition>)

like to replace function 'foo' with a macro of the above nature
if (<condition>)

Converting an array to a function arguments list [duplicate]
...that works, why won't this work? document.body.setAttribute.apply( this, ["foo", "bar"] ); I need to send variable arguments to various object methods with different argument requirements. Quick edit: Apparently this has to be document.body, or whatever the parent is

Ruby ampersand colon shortcut [duplicate]
.... The colon in this case is for the symbol. So, there's & and there's :foo.
The & calls to_proc on the object, and passes it as a block to the method. In Rails, to_proc is implemented on Symbol, so that these two calls are equivalent:

something(&:foo)
Also, to_pro...
