选择以dd / mm / yy格式选择和读取日期的更好方法？

string date = DateTime.Now.ToString(\"dd/MM/yyyy\");

     DateTime dt = new DateTime();
                DateTime.TryParse(\"16/01/2011\", System.Globalization.CultureInfo.CreateSpecificCulture(\"en-GB\"),
  System.Globalization.DateTimeStyles.None, out dt);

string s = DateTime.Today.ToString(\"dd/MM/yyyy\");

DateTime d;
bool success = DateTime.TryParseExact(\"26/05/2011\", \"dd/MM/yyyy\", CultureInfo.InvariantCulture, DateTimeStyles.None, out d);

DateTime.Now.ToString( new CultureInfo(\"fr-FR\", false) );

dateString = \"16/02/2008 12:15:12\";
try 
{
     dateValue = DateTime.Parse(dateString, new CultureInfo(\"en-GB\", false));
     Console.WriteLine(\"\'{0}\' converted to {1}.\", dateString, dateValue);
}   
catch (FormatException) 
{
     Console.WriteLine(\"Unable to convert \'{0}\'.\", dateString);
}

IFormatProvider

DateTime d = DateTime.Now;
CultureInfo c = new CultureInfo(\"en-GB\", false);
string s = d.ToString(c.DateTimeFormat);

DateTime.TryParse

string s = \"01/01/2011\";
DateTime date;
if (DateTime.TryParse(s, out date))
{
    // Parsed correctly
}
else
{
    // Invalid string!
}

TryParse

CultureInfo c = new CultureInfo(\"en-GB\", false);
string s = \"01/01/2011\";
DateTime date;
if (DateTime.TryParse(s, c.DateTimeFormat, DateTimeStyles.None, out date))
{
