.NET中的静态与非静态的区别分析

public class Test
     {
         public int i = 10;
         public static int j = 20;
         public int k;

         public Test()
         {
             Console.WriteLine("i is a non-static field, its value is {0}", i);
             Console.WriteLine("j is a static field, its value is {0}", j);
         }

         public Test(int k)
         {
             this.k = k;
             Console.WriteLine("i is a non-static field, its value is {0}", i);
             Console.WriteLine("j is a static field, its value is {0}", j);
             Console.WriteLine("k is a non-static field, its value is {0}", k);
         }

         static Test()
         {
             Console.WriteLine("I am a static constructor, I couldn't contain any parameters!");
             Console.WriteLine("I couldn't access to the non-static field i, I can only access to the static field j, the value of j is {0}", j);
         }

         public void Print()
         {
             Console.WriteLine("I am a instance method, I can access both the non-static field and the static field!");
             Console.WriteLine("The value of i is {0} and the value of j is {1}", i, j);
         }

         public static void StaticPrint()
         {
             Console.WriteLine("I am a static method, I couldnt access to the non-static field i,  I can only access to the static field j, the value of j is {0}", j);
