C#实现向函数传递不定参数的方法

using System;class Min{ public int MinVla(params int [] nums){  int m;  if (nums.Length == 0){   Console.WriteLine("Error: no arguments.");   return 0;  }  m = nums[0];  foreach ( int val in nums){   if ( val < m){    m = val;   }  }  return m; }}class ParamsDemo{ static void Main(){  Min ob = new Min();  int min;  int a=10,b=20;  min = ob.MinVla(a,b);  Console.WriteLine("Minimum is " + min);  min = ob.MinVla(a,b,-1);  Console.WriteLine("Minimum is " + min);  min = ob.MinVla(18,23,3,14,25);  Console.WriteLine("Minimum is " + min);  int [] args = {45,67,34,9,112,8};  min = ob.MinVla(args);  Console.WriteLine("Minimum is " + min); }}
