Converting time to Military

Question

In an attempt to turn a date with a format of \"mm/dd/yyyy hh:mm:ss PM\" into military time, the following replacement of a row value does not seem to take. Eve

Answer 1

Try

row["adate"].Text = oos.ToString("MM/dd/YYYY HH:mm");

Answer 2

In C# >= 6.0 you can use string interpolation as well if you need to add something around your date. Something like:

row["adate"] = $"S: {StartDateTime:yyyy-MM-dd HH:mm:ss}";

Answer 3

Simple way is

bool timeConversion = DateTime.TryParse(s,out DateTime time);

if(timeConversion)
{
return time.Tostring("HH:mm:ss");
}

here be careful to write "HH"

Answer 5

Instead of formatting the string manually, you should use:

oos.ToString("M/d/yyyy HH:mm");

Also, what do you mean by "would not accept a value"? Are you getting an exception? If so, what is the error message?

Answer 6

If you have this time: 07:12:02PM and you want this: 19:12:02PM, then this is the code for you!

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
class Solution {

    static string timeConversion(string s) {
       DateTime dateTime = DateTime.ParseExact(s, "hh:mm:sstt", 
        System.Globalization.CultureInfo.InvariantCulture); 

        return (dateTime.ToString("HH:mm:ss"));
    }

    static void Main(String[] args) {
        string s = Console.ReadLine(); 
        string result = timeConversion(s);
        Console.WriteLine(result);
    }
}
