什么是C#中的方法重载？
具有相同名称但参数不同的两个或两个以上方法在C#中称为方法重载。
可以通过更改参数的数量和参数的数据类型来执行C#中的方法重载。
假设您有一个输出数字乘法的函数，那么我们的重载方法将具有相同的名称，但参数数量不同-
public static int mulDisplay(int one, int two) { }
public static int mulDisplay(int one, int two, int three) { }
public static int mulDisplay(int one, int two, int three, int four) { }以下是显示如何实现方法重载的示例-
示例
using System;
public class Demo {
public static int mulDisplay(int one, int two) {
return one * two;
}
public static int mulDisplay(int one, int two, int three) {
return one * two * three;
}
public static int mulDisplay(int one, int two, int three, int four) {
return one * two * three * four;
}
}
public class Program {
public static void Main() {
Console.WriteLine("Multiplication of two numbers: "+Demo.mulDisplay(10, 15));
Console.WriteLine("Multiplication of three numbers: "+Demo.mulDisplay(8, 13, 20));
Console.WriteLine("Multiplication of four numbers: "+Demo.mulDisplay(3, 7, 10, 7));
}
}输出结果
Multiplication of two numbers: 150 Multiplication of three numbers: 2080 Multiplication of four numbers: 1470
