   public static void Main()
   {
      Complex[] values= { new Complex(12.3, -1.4), 
                          new Complex(-6.2, 3.1), 
                          new Complex(8.9, 1.5) };   
      foreach (var c1 in values)
         foreach (var c2 in values)
            Console.WriteLine("{0} + {1} = {2}", c1, c2, 
                              Complex.Add(c1, c2));
   }
}
// The example displays the following output:
//       (12.3, -1.4) + (12.3, -1.4) = (24.6, -2.8)
//       (12.3, -1.4) + (-6.2, 3.1) = (6.1, 1.7)
//       (12.3, -1.4) + (8.9, 1.5) = (21.2, 0.1)
//       (-6.2, 3.1) + (12.3, -1.4) = (6.1, 1.7)
//       (-6.2, 3.1) + (-6.2, 3.1) = (-12.4, 6.2)
//       (-6.2, 3.1) + (8.9, 1.5) = (2.7, 4.6)
//       (8.9, 1.5) + (12.3, -1.4) = (21.2, 0.1)
//       (8.9, 1.5) + (-6.2, 3.1) = (2.7, 4.6)
//       (8.9, 1.5) + (8.9, 1.5) = (17.8, 3)

注解

Add 方法允许执行涉及复数的加法运算。The Add methods allow performing addition operations that involve complex numbers.

如果方法调用导致实部或虚部溢出,则组件的值为 Double.PositiveInfinityDouble.NegativeInfinityIf the method call results in an overflow in either the real or imaginary component, the value of the component is either Double.PositiveInfinity or Double.NegativeInfinity.

不支持自定义运算符的语言可以使用 Add 方法来执行包含复数的加法运算。Languages that do not support custom operators can use the Add method to perform addition with complex numbers.

接收一个 double 的 Add 方法比接收两个复数的方法更有效。The Add methods that receive one double are more efficient than the methods that receive two complex numbers.
