C# DateTime FromBinary

Description

DateTime FromBinary deserializes a 64-bit binary value and recreates an original serialized DateTime object.

Syntax

DateTime.FromBinary has the following syntax.

public static DateTime FromBinary(
  long dateData
)

Parameters

DateTime.FromBinary has the following parameters.

• dateData - A 64-bit signed integer that encodes the Kind property in a 2-bit field and the Ticks property in a 62-bit field.

Returns

DateTime.FromBinary method returns An object that is equivalent to the DateTime object that was serialized by the ToBinary method.

Example

You can determine whether a particular date and time value may be subject to modification by passing it to the TimeZoneInfo.IsInvalidTime method, as the example illustrates.

/*from  ww w  .j  av  a 2s  .  c o  m*/
using System;

public class Example
{
   public static void Main()
   {
      DateTime localDate = new DateTime(2010, 3, 14, 2, 30, 0, DateTimeKind.Local);
      long binLocal = localDate.ToBinary();
      if (TimeZoneInfo.Local.IsInvalidTime(localDate))
         Console.WriteLine("{0} is an invalid time in the {1} zone.", 
                           localDate, 
                           TimeZoneInfo.Local.StandardName);

      DateTime localDate2 = DateTime.FromBinary(binLocal);
      Console.WriteLine("{0} = {1}: {2}", 
                        localDate, localDate2, localDate.Equals(localDate2));
   }
}

The code above generates the following result.
