此方法用于将两个指定的十进制值相加。
Syntax: public static decimal Add (decimal a1, decimal a2);
Parameters:
a1: This parameter specifies the first value to add.
a2: This parameter specifies the second value to add.
Return Value: Decimal sum of a1 & a2.
例外：如果a1和a2的总和小于Decimal的最小可能值或大于Decimal的最大可能值，则此方法将给出OverflowException 。
下面的程序说明了Decimal.Add(Decimal，Decimal)方法的用法
范例1：
// C# program to demonstrate the
// Decimal.Add(Decimal, Decimal)
// Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring the decimal
// variables
Decimal a1 = .01m;
Decimal a2 = .03m;
// adding the two Decimal value
// using Add() method;
Decimal value = Decimal.Add(a1, a2);
// Display the sum
Console.WriteLine("Decimal Sum : {0}",
value);
}
catch (OverflowException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
输出：
Decimal Sum : 0.04
示例2：对于OverflowException
// C# program to demonstrate the
// Decimal.Add(Decimal, Decimal)
// Method
using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring the decimal variables
Decimal a1 = 1.01m;
Decimal a2 = Decimal.MaxValue;
// adding the two Decimal value
// using Add() method;
Decimal value = Decimal.Add(a1, a2);
// Display the sum
Console.WriteLine("Decimal Sum : {0}",
value);
}
catch (OverflowException e)
{
Console.Write("Exception Thrown: ");
Console.Write("{0}", e.GetType(), e.Message);
}
}
}
输出：
Exception Thrown: System.OverflowException
