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:
Example 1:
// C# program to demonstrate the // DateTime.FromBinary(Int64) Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
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();
// converting 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);
}
}
} |
Output:
DateTime before operation: 2010 January 01 DateTime after operation: 2010 January 01
Example 2: For ArgumentOutOfRangeException
// C# program to demonstrate the // DateTime.FromBinary() Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// converting 64-bit into DateTime format
// using FromBinary() method
DateTime date = DateTime.FromBinary(-100000000000000000);
// Display the date
System.Console.WriteLine( "\nDateTime: + {0:y} {0:dd} " , date);
}
catch (ArgumentException e)
{
Console.WriteLine( "The resulting dateData"
+ " is less than the MinValue " );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
} |
Output:
The resulting dateData is less than the MinValue Exception Thrown: System.ArgumentException
