Convert.ToDateTime Method (Object, IFormatProvider)
Converts the value of the specified object to a DateTime object, using the specified culture-specific formatting information.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.IFormatProvider
An object that supplies culture-specific formatting information.
The return value is the result of invoking the IConvertible.ToDateTime method of the underlying type of value.
provider enables the user to specify culture-specific conversion information about the contents of value. For example, if value is a String that represents a date, provider could supply culture-specific information about the notation used to represent that date. provider is involved in the conversion of value if the runtime type of value is a String, or if value is a user-defined type whose IConvertible.ToDateTime implementation makes use of provider. If the runtime type of value is String and provider is a null reference (Nothing in Visual Basic), the CultureInfo object that represents the current thread culture is used.
The following example defines a custom format provider, CustomProvider, whose GetFormat method outputs a message to the console that it has been invoked, and then returns the DateTimeFormatInfo object of the culture whose name was passed as a parameter to its class constructor. Each of these CustomProvider objects is used to convert the elements in an object array to date and time values. The output indicates that the CustomProvider object is used in the conversion only when the type of the value parameter is a String.
