在 C# 中,两个或两个以上具有相同名称但不同参数的方法被称为方法重载。
C# 中的方法重载可以通过更改参数的数量和参数的数据类型来实现。
假设你有一个打印数字乘法的函数,那么我们重载的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) { }
以下示例展示了如何实现方法重载 −
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
Multiplication of two numbers: 150 Multiplication of three numbers: 2080 Multiplication of four numbers: 1470
