Question

I have a c# method:

public void foo (DateTime toDate) { ... }

when I invoke that method, visual studio intellisense suggest an option of

foo (toDate :    )

What does that syntax mean ? sending anonymous var ?

Thanks for any clarification

Answer 1

Those are for named parameters. See also http://geekswithblogs.net/michelotti/archive/2009/01/22/c-4.0-named-parameters-for-better-code-quality.aspx

So you can pass the arguments by name in any order you like. This is new in the C# 4.0 compiler.
