DateTimeConverter Class

Provides a type converter to convert DateTime objects to and from various other representations.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public class DateTimeConverter : TypeConverter


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

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.


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.

The following code example converts a variable of type DateTime to a string, and vice versa.

DateTime dt=new DateTime(1990,5,6);
Console.WriteLine(TypeDescriptor.GetConverter(dt).ConvertTo(dt, typeof(string)));
string myStr="1991-10-10";


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
