C# – How to get the current date without the time

I am able to get date and time using:

DateTime now = DateTime.Now;

How can I get the current date and time separately in the DateTime format itself?

I am not using the DateTime picker dialog box in ASP.NET (C#).

Well, you can get just today's date as a DateTime using the Today property:

 DateTime today = DateTime.Today;

or more generally, you can use the Date property. For example, if you wanted the UTC date you could use:

 DateTime dateTime = DateTime.UtcNow.Date;

It's not very clear whether that's what you need or not though... if you're just looking to print the date, you can use:

Console.WriteLine(dateTime.ToString("d"));

or use an explicit format:

Console.WriteLine(dateTime.ToString("dd/MM/yyyy"));

See more about standard and custom date/time format strings. Depending on your situation you may also want to specify the culture.

If you want a more expressive date/time API which allows you to talk about dates separately from times, you might want to look at the Noda Time project which I started. It's not ready for production just yet, but we'd love to hear what you'd like to do with it...

C# – How to get the index of the current iteration of a foreach loop

Ian Mercer posted a similar solution as this on Phil Haack's blog:

foreach (var item in Model.Select((value, i) => new { i, value }))
{
    var value = item.value;
    var index = item.i;
}

This gets you the item (item.value) and its index (item.i) by using this overload of LINQ's Select:

the second parameter of the function [inside Select] represents the index of the source element.

The new { i, value } is creating a new anonymous object.

Heap allocations can be avoided by using ValueTuple if you're using C# 7.0 or later:

foreach (var item in Model.Select((value, i) => ( value, i )))
{
    var value = item.value;
    var index = item.i;
}

You can also eliminate the item. by using automatic destructuring:

<ol>
foreach ((MyType value, Int32 i) in Model.Select((value, i) => ( value, i )))
{
    <li id="item_@i">@value</li>
}
</ol>

C# – How to enumerate an enum

foreach (Suit suit in (Suit[]) Enum.GetValues(typeof(Suit)))
{
}

Note: The cast to (Suit[]) is not strictly necessary, but it does make the code 0.5 ns faster.
