DateTime.TryParse(s, out dt)

网上看到的DateTime.TryParse(s, out dt)例子，一般是对YY-MM-DD的格式有效。这好像是默认的吧？现在我想让它能对MM-DD—YY也能转换。怎么办？
例如：
DateTime dt;
DateTime.TryParse("02-01-09", out dt);
默认的情况会得到：02年1月9号；我想得到09年2月1号

public static bool TryParse (
string s,
IFormatProvider provider,
DateTimeStyles styles,
out DateTime result
)
怎么用MSDN没有详细的说明,郁闷!

参照如下代码：
string[] dateStrings = {"05/01/2009 14:57:32.8", "2009-05-01 14:57:32.8",

"2009-05-01T14:57:32.8375298-04:00",

"5/01/2008 14:57:32.80 -07:00",

"1 May 2008 2:57:32.8 PM", "16-05-2009 1:00:32 PM",

"Fri, 15 May 2009 20:10:57 GMT" };
DateTime dateValue;
Console.WriteLine("Attempting to parse strings using {0} culture.",

CultureInfo.CurrentCulture.Name);
foreach (string dateString in dateStrings)
{
if (DateTime.TryParse(dateString, out dateValue))
Console.WriteLine("Converted '{0}' to {1} ({2}).", dateString,

dateValue, dateValue.Kind);
else
Console.WriteLine("Unable to parse '{0}'.", dateString);
}
// The example displays the following output:
//Attempting to parse strings using en-US culture.
