TimeSpan.Add() Method in C#

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

Syntax public TimeSpan Add (TimeSpan t);

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

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

Exception:OverflowException:It occurs when the resulting TimeSpan is smaller than smallest possible value or greater than the largest possible value.

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

Example 1:

// C# program to demonstrate the 
// TimeSpan.Add(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.Add(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 : 5:09:50:49

Example 2: For Overflow Exception

// C# program to demonstrate the 
// TimeSpan.Add(TimeSpan) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // the TimeSpan object 
            TimeSpan t1 = new TimeSpan(3, 22, 35, 33); 
            TimeSpan t2 = TimeSpan.MaxValue; 
            TimeSpan variable = t1.Add(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
