I store this in my db as time(7) , I want the time to appear in 4:03pm . Not like this. I use this method but failed, string is not a valid datetime

C#

string timeFromFormat = "hh:mm tt";
DateTime timeFrom = DateTime.ParseExact(tb_TimeFrom.Text, timeFromFormat, CultureInfo.InvariantCulture);

Sorry, but that doesn't make a whole lot of sense.
You talk about a DB but there is no obvious DB code there, just an attempt to convert from a string to a DateTime, using a very specific format - which your example value does not match. And there is no presentation of dates or time involved: you just try to create a DateTime which you can't display directly.

Please edit your question, and try to explain in fuller details what you are trying to do, what you are inputting, and what you are expecting as an output.

The string data you show is not a DateTime: it's a TimeSpan. To convert a TimeSpan into a usable representation of a point in time, you have to do something like this:

private void TestConversion()
{
    string dbDataString = "16:03:19.0830000";
    
    // match the format of the TimeSpan in the Database
    string timeFromFormat = "hh\\:mm\\:ss\\.fffffff";
    
    // output format
    string simpleAMPM = "{0:h:mm tt}";
    
    // convert to TimeSpan
    TimeSpan ts = TimeSpan.ParseExact(dbDataString, timeFromFormat, CultureInfo.InvariantCulture);
    
    // add the TimeSpan to a DateTime
    DateTime theDate = new DateTime() + ts;
    
    // format the result
    string theTime = string.Format(simpleAMPM, theDate);
    
    // check output ...
    Console.WriteLine(theTime);
}

Solution 2

Please try is as below.

DateTime myDate = DateTime.ParseExact("16:03:19,083", "HH:mm:ss,fff",
                          System.Globalization.CultureInfo.InvariantCulture);
 
        Console.WriteLine(myDate.ToString("hh:mm tt"));

Solution 1

string timeFromFormat = "hh:mm tt";is wrong.
It should be string timeFromFormat = "hh:mm:tt";

"hh:mm tt" is not wrong if it's used on a DateTime ! But, in this case what the OP has is a TimeSpan, not a DateTime. See my answer below.
