先来看一下代码:
using System;
using System.Collections.Generic;
using System.Text;

namespace ChBurden
{
    class Program
    {
        //所定义的类型是int的myStatic函数:
        static int myStatic(int[] comeInt)
        {
            int keepInt;
            keepInt = comeInt[0];

            for (int i = 1; i < comeInt.Length; i++)
            {
                if (comeInt[i] > keepInt)
                {
                    keepInt = comeInt[i];
                }
            }

            Console.WriteLine("以上是Int的输出");
            return keepInt;
        }

        //所定义的类型是double的myStatic的函数:
        static double myStatic(double[] comeDouble)
        {
            double keepDouble;
            keepDouble = comeDouble[0];

            for (int i = 1; i < comeDouble.Length; i++)
            {
                if (comeDouble[i] > keepDouble)
                {
                    keepDouble = comeDouble[i];
                }
            }

            Console.WriteLine("以上是Double的输出");
            return keepDouble;
        }
       
        static void Main(string[] args)
        {
            //被声明int类型的:
            int[] myInt ={25,87,65,100,325,56,987,102};
            //被声明double类型的:
            double[] ōkDouble = {51102,23548,98710,3548,21456,56871};
            double myDouble;

            //由于myInt是int类型,所以会选择第一个myStatic的函数
            myDouble = myStatic(myInt);            
            Console.WriteLine("{0}",myDouble);

            //由于okDouble是double类型,所以会选择第二个myStatic的函数
            myDouble = myStatic(okDouble);
            Console.WriteLine("{0}",myDouble);
            Console.ReadKey();
        }
    }
}

说明如下:
在上述的代码中,采用的是函数重载的方法进行处理.原理是:多个函数采用相同的函数名,但所定义的类型和所定义的形参不相同,当调用相应的代码时,会按照所传递的实参的类型而去定位所被调用的函数,而且也可以按照相参数的个数来进行定位.
