今天就跟大家聊聊有關(guān)C#中怎么通過(guò)運(yùn)算符重載實(shí)現(xiàn)復(fù)數(shù)運(yùn)算,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結(jié)了以下內(nèi)容,希望大家根據(jù)這篇文章可以有所收獲。

C#運(yùn)算符重載實(shí)現(xiàn)復(fù)數(shù)運(yùn)算的由來(lái):函數(shù)的重載——同名函數(shù),不同的參數(shù)(包括參數(shù)個(gè)數(shù)不同和參數(shù)個(gè)數(shù)相同但個(gè)數(shù)不同)
將其引申,像如下的代碼:
int i=5; int j=2; int sum=i+j;
如果沒(méi)有自定義的C#運(yùn)算符重載,像+,-,*,/這樣的運(yùn)算符只能用于預(yù)定義的數(shù)據(jù)類型,編譯器認(rèn)為所有常見(jiàn)的運(yùn)算符都是用于這些數(shù)據(jù)類型的。
問(wèn)題來(lái)了,如果我要對(duì)兩個(gè)復(fù)數(shù)或矩陣進(jìn)行四則運(yùn)算,就需要我們自己擴(kuò)展運(yùn)算符重載函數(shù)了。
C#運(yùn)算符重載之示例:復(fù)數(shù)的四則運(yùn)算
public struct Complex { public int real; public int imaginary; public Complex(int real, int imaginary) { this.real = real; this.imaginary = imaginary; } //overload operator(+),added(two Complex objects) and return a Complex type public static Complex operator +(Complex c1, Complex c2) { return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary); } //overload operator(-) public static Complex operator -(Complex c1, Complex c2) { return new Complex(c1.real - c2.real, c1.imaginary - c2.imaginary); } //overload operator(*) public static Complex operator *(Complex c1, Complex c2) { return new Complex(c1.real * c2.real - c1.imaginary * c2.imaginary, c1.real * c2.imaginary + c1.imaginary * c2.real); } //overload operator(/) public static Complex operator /(Complex c1, Complex c2) { return new Complex(-c1.real * c2.real + c1.imaginary * c2.imaginary, -c1.real * c2.imaginary + c1.imaginary * c2.real); } // Override the ToString method to display an complex number in the suitable format: public override string ToString() { return (String.Format("{0} + {1}i", real, imaginary)); } }
C#運(yùn)算符重載之客戶端代碼:
static void Main(string[] args) { Complex num1 = new Complex(2, 3); Complex num2 = new Complex(3, 4); //Add two Complex objects (num1 and num2) through the overloaded plus operator: Complex sum_Add = num1 + num2; Complex sum_Minus = num1 - num2; Complex sum_Product = num1 * num2; Complex sum_Divide = num1 / num2; //Print the numbers and the Result using the overriden ToString method: Console.WriteLine("First complex number: {0}", num1); Console.WriteLine("Second complex number: {0}", num2); Console.WriteLine("The sum of the two numbers: {0}", sum_Add); Console.WriteLine("The Minus of the two numbers: {0}", sum_Minus); Console.WriteLine("The Product of the two numbers: {0}", sum_Product); Console.WriteLine("The Divide of the two numbers: {0}", sum_Divide); Console.ReadLine(); }
C#運(yùn)算符重載實(shí)例運(yùn)行結(jié)果:
First complex number: 2 + 3i Second complex number: 3 + 4i The sum of the two numbers: 5 + 7i The Minus of the two numbers: -1 + -1i The Product of the two numbers: -6 + 17i The Divide of the two numbers: 6 + 1i
