One of the searches that came from Google to my site asked the following "c# convert date from uk to usa".
Now I don't really know exactly what the user was asking for, but I presume it is something fairly simple. The way that I would convert a UK date into a US date is as follows.
Read in the UK date, short format/long format whatever into a DateTime field. The output the date time using a US locale.
The following code works in vs2005.
CultureInfo cultEnGb = new CultureInfo("en-GB");
CultureInfo cultEnUs = new CultureInfo("en-US");
DateTime dtGb = Convert.ToDateTime(textBox1.Text, cultEnGb.DateTimeFormat);
textBox2.Text = dtGb.ToString(cultEnUs.DateTimeFormat.ShortDatePattern);
It reads in the date and tries to load the text as a UK Date from the first textbox and then it uses the US locale to output the string into the second textbox.
