DateTimeOffset.ToOffset() Method in C#

DateTimeOffset.ToOffset(TimeSpan) Method is used to convert the value of the current DateTimeOffset object to the date and time specified by an offset value.

Syntax: public DateTimeOffset ToOffset (TimeSpan offset);
Here, it takes the offset to convert the DateTimeOffset value to.

Return Value: This method returns an object that is equal to the original DateTimeOffset object (that is, their ToUniversalTime() methods return identical points in time) but whose Offset property is set to offset.



Exceptions:

  • ArgumentException If the resulting DateTimeOffset object has a DateTime value earlier than MinValue. Or the resulting DateTimeOffset object has a DateTime value later than MaxValue.
  • ArgumentOutOfRangeException If the offset is less than -14 hours. Or offset is greater than 14 hours.

Below programs illustrate the use of DateTimeOffset.ToOffset() Method:

            // Converts the value of 
            // the current DateTimeOffset
            // object to the date and time

            // instance using ToOffset() method
            DateTimeOffset value = offset.ToOffset(new TimeSpan(-5, 1, 0));
  
            // Display the time
            Console.WriteLine("DateTimeOffset is {0}", value);
        }
  
        catch (ArgumentOutOfRangeException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
  
        catch (ArgumentException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
