Comparing only the Datetime field date in C#

Question

I only need to compare the date of two fields DateTime.

DateTime aux = new DateTime(2016, 09, 02, 10, 0, 0);
if (aux.Equals(DateTime.Now))
{
     //Alguma ação...
}

In the code above, I need you to enter if when the date (02/09/2016) is equal in the two objects. In this case it does not enter because the Time of the two objects is different. What should I do ?

Answer 1

You should take the Date property from Datetime for example

DateTime aux = new DateTime(2016, 09, 02, 10, 0, 0);
if (aux.Date.Equals(DateTime.Now.Date))
{
     //Alguma ação...
}

Answer 2

Marco Giovanni’s reply is correct, I decided to answer to put the idiomatic form:

var aux = new DateTime(2016, 09, 02, 10, 0, 0);
if (aux.Date == DateTime.Now.Date) {
    Console.WriteLine("Ok");
}

Behold working in the ideone. And in the .NET Fiddle. Also put on the Github for future reference.
