I'm trying to sort a string array of dates using Array.Sort(myArray). It is a one-dimensional array. I am having trouble sorting the dates. Can someone point me in the right direction? It will be greatly appreciated.
Array.Sort(myArray) sorts the array according to month but does not consider the days or the years. What can I do to fix this?
You have a couple of options here. Firstly you can format the dates as strings using YYYYMMDD with no separators. This should ensure that dates are sorted correctly.
The other way to do it is define a new type which stores a DateTime value and implements the IComparable interface. You could then store each date, in this new class, in an object array and the sort function should work correctly.
I tried using:
for (i = 1467; i < 1470; i++)
if (i + 1 != 1471)
strOne = strSort[i];
strTwo = strSort[i+1];
but it does not want to sort the dates correctly. What am I doing wrong? I am new to C#. I know I can do it manually, but I've never actually used C# methods to do this task.
Ok. Nevermind. It is not working...I have to set to storing the dates as integer values in a string array. For example: 1/31/2004 as "1312004" but its not working correctly. Can you please help me some more? Thanks.
