C# BitConverter用法及代码示例

// C# program to illustrate the 
// use of GetBytes(Int64) method 
using System; 
  
class GFG { 
  
    // Main method 
    static public void Main() 
    { 
  
        // Creating and initializing an array 
        long[] ele = {0, long.MaxValue, long.MinValue, 
                         1000000000000000, -100000000,  
                       0xDDDDDDDDD, -0xAAAAAAAAAAAA }; 
  
        // Display the elements 
        Console.WriteLine("Elements are:"); 
        foreach(long i in ele) 
        { 
            Console.WriteLine(i); 
        } 
  
        foreach(var num in ele) 
        { 
  
            // Get the specified 64-bit signed 
            // integer value as an array of bytes. 
            // using GetBytes(Int64) method 
            byte[] BArr = BitConverter.GetBytes(num); 
  
            // Display the elements 
            Console.WriteLine("Element: {0}",  
                BitConverter.ToString(BArr)); 
        } 
    } 
}

// use of Int64BitsToDouble(Int64) 
// method 
using System;

    // Main method 
    static public void Main()

        // integer to a double-precision
