TimeSpan.FromHours() Method in C#

This method is used to get a TimeSpan that represents a specified number of hours, accurate to the nearest millisecond.

Syntax: public static TimeSpan FromHours (double value);

Parameter:
value: This parameter specifies the number of hours, accurate to the nearest millisecond.

Return Value: It returns a new TimeSpan object that represents the value.

Exceptions:

• OverflowException: It occurs when the given double value is smaller than the smallest possible value or greater than the largest possible value or the value is PositiveInfinity or is NegativeInfinity.
• ArgumentException: If the value is equal to NaN.

Below programs illustrate the use of TimeSpan.FromHours(Double) Method:

Program 1:

// C# program to demonstrate the
// TimeSpan.FromDays(Double) Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            TimeSpan interval = TimeSpan.FromHours(12.3459);
            Console.WriteLine("The Timespan is : {0}",
                                            interval);
        }

        catch (OverflowException e) {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

The Timespan is : 12:20:45.2400000

Program 2: For Overflow Exception

// C# program to demonstrate the
// TimeSpan.FromDays(Double) Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            TimeSpan interval =
               TimeSpan.FromHours(Double.NegativeInfinity);

            Console.WriteLine("The Timespan is : {0}",
                                            interval);
        }

        catch (OverflowException e)
       {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output:

Exception Thrown: System.OverflowException
