clr via c# Array2

1,Array类型生成方式以及实际类型

private static void ArrayIntro() {
      String[] sa = new String[1];
      Array a1 = Array.CreateInstance(typeof(String), new Int32[] { 1 }, new Int32[] { 0 });
      Array a2 = Array.CreateInstance(typeof(String), new Int32[] { 1 }, new Int32[] { 1 });
      Console.WriteLine(sa.GetType().ToString());
      Console.WriteLine(a1.GetType().ToString());
      Console.WriteLine(a2.GetType().ToString());
   }
//System.String[]
//System.String[]
//System.String[*]

2,Array 的维度---used Rank to 指示数组的秩.

 private static void ArrayRankInfo(String name, Array a) {
      Console.WriteLine("Number of dimensions in \"{0}\" array (of type {1}): ",
         name, a.GetType().ToString(), a.Rank);
      for (int r = 0; r < a.Rank; r++) {
         Console.WriteLine("Rank: {0}, LowerBound = {1},  UpperBound = {2}",
            r, a.GetLowerBound(r), a.GetUpperBound(r));
      }
      Console.WriteLine();
   }

3,Array-----其他特性...
