TimeSpan.Subtract() Method in C#

This method is used to a get new TimeSpan object whose value is the difference of the specified TimeSpan object and this instance.

Syntax: public TimeSpan Subtract (TimeSpan t);

Parameter:
t: This parameter specifies the time interval to be subtracted.

Return Value: It returns a new TimeSpan object whose value is the difference current instance and the value of t.

Exception: This method will give OverflowException when the resulting TimeSpan is smaller than smallest possible value or greater than the largest possible value.

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

Example 1:

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

class GFG {

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

            // creating the TimeSpan object
            TimeSpan t1 = new TimeSpan(3, 22, 35, 33);
            TimeSpan t2 = new TimeSpan(1, 11, 15, 16);
            TimeSpan variable = t1.Subtract(t2);

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

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

Output:

The Timespan is : 2.11:20:17

Example 2: For Overflow Exception

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

class GFG {

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

            // the TimeSpan object
            TimeSpan t1 = TimeSpan.MinValue;
            TimeSpan t2 = new TimeSpan(3, 22, 35, 33);
            TimeSpan variable = t1.Subtract(t2);

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

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

Output:

Exception Thrown: System.OverflowException
