本人是新鸟刚学C#不久~~~有很多还不懂~~~~~~望老鸟们多多指导哈

比如这段代码:

using System;
using System.Collections.Generic;
using System.Text;

namespace Example01
{
     class Program
     {
         class Class1
         {
             public static String staticStr = "Class";
             public String notstaticStr = "Obj";
         }
         static void Main(string[] args)
         {
             //静态变量通过类进行访问，该类所有实例的同一静态变量都是同一个值
             Console.WriteLine("Class1's staticStr: {0}", Class1.staticStr);

             Class1 tmpObj1 = new Class1();
             tmpObj1.notstaticStr = "tmpObj1";
             Class1 tmpObj2 = new Class1();
             tmpObj2.notstaticStr = "tmpObj2";

             //非静态变量通过对象进行访问，不同对象的同一非静态变量可以有不同的值
             Console.WriteLine("tmpObj1's notstaticStr: {0}", tmpObj1.notstaticStr);
             Console.WriteLine("tmpObj2's notstaticStr: {0}", tmpObj2.notstaticStr);

             Console.ReadLine();
         }
     }
}
结果：
Class1's staticStr: Class
tmpObj1's notstaticStr: tmpObj1
tmpObj2's notstaticStr: tmpObj2



他什么时候该用大括号,还有怎么会知道引用这些变量等等

望老鸟门帮我上上课了!~~~谢谢了
