DateTime.ToString () displays the meridiem as "AM" or "PM"

Question

Is it possible to use the DateTime.ToString () method to display the meridium of the time part as "AM" instead of "AM"? I tried using the mask "tt" but it just displays "AA"

Answer 1

You can override the properties AMDesignatorand PMDesignator CultureInfo.DateTimeFormat, and then specify the culture as the format provider:

using System;
using System.Globalization;

class Program {
    public static void Main() {
        CultureInfo c = (CultureInfo)CultureInfo.CurrentCulture.Clone();
        c.DateTimeFormat.AMDesignator = "A.M.";
        c.DateTimeFormat.PMDesignator = "P.M.";
        Console.WriteLine(DateTime.Now.ToString("tt",c));
    }
}

Answer 2

Use "t.\\M":

DateTime time = DateTime.Now;
string s = time.ToString("yyyy.MM.dd hh:mm:ss t.\\M.");
Console.WriteLine(s);

Output:

2010.02.02 09:26:14 A.M.

: t AM/PM ( DateTimeFormatInfo.AMDesignator DateTimeFormatInfo.PMDesignator). \\M M, DateTime.ToString .

, , . , AM/PM , .
