I try to get DateTime.Now , but what I get is:

'23/05/2016 03:16:51 ق.ظ'

I want to have

'23/05/2016 03:16:51 AM'

or something like this

Then you current culture seems to be an arabic one. You can use the overload of DateTime.ToString:

var enUsCulture = new CultureInfo("en-US");
string result = DateTime.Now.ToString( enUsCulture );

an an alternative you could pass the exact format with CultureInfo.InvariantCulture(to avoid that / will be replaced with your current culture's date separator):

string result = DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);

The InvariantCulture avoids that the "/" custom format specifier will cause / to be replaced with your current culture's date separator.

You could create a specific CultureInfo with your requirements starting from the CurrentCulture

CultureInfo ci = new CultureInfo(CultureInfo.CurrentCulture.LCID);
ci.DateTimeFormat.AMDesignator = "AM";
ci.DateTimeFormat.PMDesignator = "PM";
ci.DateTimeFormat.LongTimePattern = "HH:mm:ss tt";
string result = DateTime.Now.ToString(ci);
Console.WriteLine(result);

I think CultureInfo.InvariantCulture is the key here

 DateTime now = DateTime.Now;
 string result = now.ToString("dd MMM yyyy hh:mm tt", CultureInfo.InvariantCulture);
 Console.WriteLine(result);

This should give you "23 May 2016 02:32 PM", you can further edit the date and time by using other setting in the string format specifier. But keep InvarianCulture and tt in order to recieve AP/PM.
