Answer 2

+7 A:

You might try:

EDIT:

DateTime d;
DateTime.TryParse("12/10/2010 00:00:00", d);
d.ToString("MM/dd/yyyy");

-1, I think you should check your code. http://msdn.microsoft.com/en-us/library/ch92fbc1.aspx

@Codesleuth - Tru dat. Hasty code typing early in the morning. Thanx.

Joel Etherton 2010-10-29 12:40:14

Cool, removed the downvote :)

Answer 3

+6 A:

This takes the first half of your string before the space:

   string formatedDt = "12/10/2010 00:00:00".Split(' ')[0];

Steve Danner 2010-10-29 12:37:12

Doesn't compile since string.Split is a member method and not a static function.

Good call, I fixed it.

Answer 4

+4 A:

string s =  "12/10/2010 00:00:00";
s = s.Substring(0,s.IndexOf(" ");

I think this one doesn't work if the string contains no spaces at all.

CodeInChaos 2010-10-29 12:40:08

@CodeInChaos - none of these solutions work if there is no space. Why is this answer different?

Joel Etherton 2010-10-29 12:43:26

String.Split returns the whole string as [0] if the input string doesn't contain one of the split-chars.

CodeInChaos 2010-10-29 13:08:01

@CodeInChaos - I took the question "How to remove trailing spaces after a blank space, c#" to mean that there would always be at least one space.

scott 2010-10-29 13:17:49

@Scott, I think your answer is perfectly reasonable for the question asked. In the general case, though, it's important to note that if there isn't a space in the given string, Substring will throw an ArgumentOutOfRangeException since IndexOf will return -1. For the sake of promoting safe code, I think it's at least a good idea to check the return from the IndexOf before calling Substring.

Answer 5

A:

"12/10/2010 00:00:00".Split(' ')[0]

this returns the whole string if it doesn't contain a space.

Or if you need other behavior in case of a missing space you can do this:

string s =  "12/10/2010 00:00:00";
int spaceIndex=s.IndexOf(" ");
if(spaceindex>=0)
{
    return = s.Substring(0,spaceIndex);
}
else
{
    //Handle the case without space here
    //For example throw a descriptive exception
    throw new InvalidDataException("String does not contain a space");
}

CodeInChaos 2010-10-29 13:05:43

If there is no space, the returned string is "12/10/201000:00:00" which is not what OP wants.

Joel Etherton 2010-10-29 13:07:40

It's unclear what the OP want. Both returning the whole string and thus making the operation idempotent and throwing a descriptive exception seem reasonable to me. Throwing an ArgumentOutOfRangeException exception on the other hand doesn't seem reasonable to me.

CodeInChaos 2010-10-29 13:19:43

There must be a space because OP gave space in example input.

Answer 6

+6 A:

Everyone else has answered the question directly, however I have a feeling that what you really need is to become familier with the various ways System.DateTime provides to generate a string representation:

DateTime.ToShortDateString

DateTime.ToShortTimeString

DateTime.ToString(string)
