Question

I am trying to sort my data in the array list.

For example the format of the data is as below:

“9:34 AM~Schedule 12” .

And i want it to sort according to the time only “9:34 AM~Schedule 12″ .

Below is the code to sort it but it doesn’t seem to work:

Array.Sort(timeSplit, delegate(string first, string second, string third)
{
    return DateTime.Compare(Convert.ToDateTime(first), Convert.ToDateTime(second), third);
});

Answer 1

First you should remove the third string because the sort delegate only takes two parameters.
Second the data you pass it is not a valid DateTime you should convert it to date time first.
So:

Array.Sort(timeSplit, delegate(string first, string second)
{
    //assuming all data have the same format: "9:34 AM~Schedule 12" .
    int firstLength = first.IndexOf("~");
    int secondLength = second.indexOf("~");

    return DateTime.Compare(Convert.ToDateTime(first.Substring(0, firstLength)), Convert.ToDateTime(second.Substring(0, secondLength)));
});
