C＃中的TimeSpan.Add()方法

此方法用于获取新的TimeSpan对象，该对象的值是指定的TimeSpan对象与该实例的和。

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.

异常： OverflowException ：当生成的TimeSpan小于最小可能值或大于最大可能值时发生。

下面的程序说明了TimeSpan.Add(TimeSpan)方法的用法：

范例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);
        }
    }
}

输出：

The Timespan is : 5:09:50:49

示例2：对于溢出异常

// 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);
        }
    }
}

输出：

Exception Thrown: System.OverflowException
