基础数据类型与字节数组相互转换 BitConvter类

using System;

public class Example
{
   public static void Main()
   {
      int value = 1234;
      byte[] bytes = BitConverter.GetBytes(value);//将int转换为bytes数组
      Console.WriteLine(BitConverter.ToString(bytes));//将byts数组转换为16进制形式的字符

      if (BitConverter.IsLittleEndian)
         Array.Reverse(bytes); 

      Console.WriteLine(BitConverter.ToString(bytes));
      // Call method to send byte stream across machine boundaries.

      // Receive byte stream from beyond machine boundaries.
      Console.WriteLine(BitConverter.ToString(bytes));
      if (BitConverter.IsLittleEndian)
         Array.Reverse(bytes);

      Console.WriteLine(BitConverter.ToString(bytes));
      int result = BitConverter.ToInt32(bytes, 0);将bytes数组转换为int
      Console.WriteLine("Original value: {0}", value);
      Console.WriteLine("Returned value: {0}", result);
   }
}
