函数作用域的示例

函数只能在其定义的代码块中使用。

using System;
namespace a
{
	class Program
	{
		static void Write()
		{
			string myString ="String defined in Write()";
			Console.WriteLine("Now in Write()");
			Console.WriteLine("myString={0}",myString);
		}
		static void Main(string[] args)
		{
			string myString="String defined in Main()";
			Write();
			Console.WriteLine("\nNow in Main()");
			Console.WriteLine("myString={0}",myString);
			Console.ReadKey();
		}
	}
}
