Log file is not showing milliseconds of a timestamp

I have the following log to a text file method: I wanted to include a time stamp like this (2014-01-23 09:42:20.020 AM) but when I look at my log file it doesn't include the .020 time. Did I miss to format something?

// Build timestamp string
var currentDateTime = DateTime.Now;
string timeStampString =   currentDateTime.ToString("ddMMyyyy_HHmmssms");

// Build filename  messages, concat timestamp and .txt extension.
string debugFileName = "C:\\Test" + timeStampString  + ".txt";
var inboundMessageLog = new StreamWriter(debugFileName, false, System.Text.Encoding.Default);
// Write to the file:
inboundMessageLog.WriteLine(DateTime.Now);
inboundMessageLog.WriteLine("TimeStampString = {0}", timeStampString);
inboundMessageLog.WriteLine("Inbound message = {0}", strMessage);
inboundMessageLog.Close();
// -------------------------------------------------------------------------------------------

}

Thank you for your time.

UPDATE:

This format:

   string  timeStampString = currentDateTime.ToString("yyyy-MM-dd hh:mm:ss:fff tt") or .fff tt;

didn't work for me. I see my logs only when I use

   string timeStampString = currentDateTime.ToString("yyyyMMdd hhmmss");

Problem : You are using ms to represent the Milliseconds.

Solution : there is no custom format ms You need to use fff to represent MilliSeconds

fff The milliseconds in a date and time value.

if you want to get the Date and Time in the format of (2014-01-23 09:42:20.020 AM)

You need to use this format yyyy-MM-dd hh:mm:ss.fff tt

Try This:

string timeStampString = currentDateTime.ToString("yyyy-MM-dd hh:mm:ss.fff tt");

EDIT : if you want custome format as dd-MM-yyyy_HH:mm:ss:fff

Try This:

string timeStampString = currentDateTime.ToString("dd-MM-yyyy_HH:mm:ss:fff tt");

Explanation:

yyyy - Year in 4 digits
MM - Month in two digits
dd - Date in two digits

hh - Hours in two digits.
mm - Minutes in two digits.
ss - Seconds in two digits.

fff - Milliseconds
tt - AM or PM.
