static.cs

深入浅出C＃,学习C#比较好的用例,能够很快掌握C#.

using System;

class Getsum
{
	public static void sum(double d)//静态方法
	{
		Mainclass.sum+=d;//直接用类名引用静态成员
	}
}

class Mainclass
{
	public static double sum;//静态成员
	public static void Main()
	{
		int proceed=1;
		Console.WriteLine("计算和:");
		while(proceed==1)
		{
			Console.WriteLine("请输入要加入总和的值:");
			string s=Console.ReadLine();
			double d=double.Parse(s);
			Getsum.sum(d);//不用实例对象引用
			Console.WriteLine("now the sum of all the value is:{0}",sum);
			Console.Write("do you want to continue?1=yes,2=no:");
			string str=Console.ReadLine();
			proceed=int.Parse(str);
		}
		Console.WriteLine("总和为：{0}",sum);
	}
