Examples
The following code example converts a variable of type DateTime to a string, and vice versa.
DateTime dt(1990,5,6);
Console::WriteLine( TypeDescriptor::GetConverter( dt )->ConvertTo( dt, String::typeid ) );
String^ myStr = "1991-10-10";
Console::WriteLine( TypeDescriptor::GetConverter( dt )->ConvertFrom( myStr ) );
DateTime dt=new DateTime(1990,5,6);
Console.WriteLine(TypeDescriptor.GetConverter(dt).ConvertTo(dt, typeof(string)));
string myStr="1991-10-10";
Console.WriteLine(TypeDescriptor.GetConverter(dt).ConvertFrom(myStr));
Dim dt As New DateTime(1990, 5, 6)
Console.WriteLine(TypeDescriptor.GetConverter(dt).ConvertTo(dt, GetType(String)))
Dim myStr As String = "1991-10-10"
Console.WriteLine(TypeDescriptor.GetConverter(dt).ConvertFrom(myStr))
Remarks
This converter can only convert a DateTime object to and from a string.
The ConvertFrom method uses the Parse method of the DateTime class to convert from a string.
The ConvertTo method uses the current culture, if a CultureInfo is not supplied. Generally, ConvertTo uses the ShortDatePattern property to format a date and ShortDatePattern with the ShortTimePattern property to format a date and time. If the InvariantCulture property is passed, ConvertTo uses yyyy-MM-dd to format a date and ToString to format a date and time.
For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.
Note
You should never create an instance of DateTimeConverter. Instead, call the GetConverter method of the TypeDescriptor class. For more information, see the examples in the TypeConverter base class.
