Gets or sets the custom format string for a month and day value.
Assembly: mscorlib (in mscorlib.dll)
The property defines the culture-specific format of date strings that are returned by calls to the DateTime..::..ToString and methods and by composite format strings that are supplied the "m" and "M" standard format strings.
We recommend that you set the date separator in the month and day pattern to an exact string instead of using the date separator placeholder. For example, to obtain the pattern MM-DD, set the month and day pattern to "MM-DD".
