DateTime.FromBinary() Method in C#

DateTime.FromBinary(Int64) Method is used to deserialize a 64-bit binary value and recreates an original serialized DateTime object.

Syntax: public static DateTime FromBinary (long dateData);
Here, it takes a 64-bit signed integer that encodes the Kind property in a 2-bit field and the Ticks property in a 62-bit field.

Return Value: This method returns an object that is equivalent to the DateTime object that was serialized by the ToBinary() method.

Exception: This method will give ArgumentException if the dateData is less than MinValue or greater than MaxValue.

Below programs illustrate the use of DateTime.FromBinary(Int64) Method:

    {
        try {
            // creating object of DateTime
            DateTime date1 = new DateTime(2010, 1, 1,
                                           8, 0, 15);
  
            // getting a 64-bit signed integer
            // using ToBinary() method
            long binLocal = date1.ToBinary();
  
            // cnverting 64-bit into DateTime format
            // using FromBinary() method
            DateTime date2 = DateTime.FromBinary(binLocal);
  
            // Display the date1
            System.Console.WriteLine("DateTime before "
                     + "operation: {0:y} {0:dd}",date1);
                                       
  
            // Display the date2
            System.Console.WriteLine("\nDateTime after"
                  + " operation: {0:y} {0:dd}", date2);
                                       
        }
  
        catch (ArgumentOutOfRangeException e) {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
