有用的BitConverter

肯定有用的到的转换，记录下来。

 ///double =>ieee754
            double d = 0.12345;
            byte[] IEEE754 = BitConverter.GetBytes(d);
            Console.WriteLine(BitConverter.ToString(IEEE754)); 

            // IEEE754转为double
            double dr = BitConverter.ToDouble(IEEE754,0);
            Console.WriteLine(dr.ToString()); 

            //double ==>long
            // IEEE 754的另一种表现形式
            long l = BitConverter.DoubleToInt64Bits(d);
            Console.WriteLine(Convert.ToString(l,16)); 

            int integer = 10;
            byte[] FInteger = BitConverter.GetBytes(integer);
            Console.WriteLine(BitConverter.ToString(FInteger));

            const string formatter = "{0,25}{1,30}";

            float aSingl = 0.1111111111111111111F;
            long aLong = 1111111111111111111;
            int anInt = 1111111111;
            short aShort = 11111;
            char aChar = '*';
            bool aBool = true;
            double aDoubl = 0.1111111111111111111;

            Console.WriteLine(
            "This example of methods of the BitConverter class" +
            "
generates the following output.
");
            Console.WriteLine(formatter, "argument", "byte array");
            Console.WriteLine(formatter, "--------", "----------");

            // Convert values to Byte arrays and display them.
            Console.WriteLine(formatter, aDoubl,
                BitConverter.ToString(BitConverter.GetBytes(aDoubl)));
            Console.WriteLine(formatter, aSingl,
                BitConverter.ToString(BitConverter.GetBytes(aSingl)));
            Console.WriteLine(formatter, aLong,
                BitConverter.ToString(BitConverter.GetBytes(aLong)));
            Console.WriteLine(formatter, anInt,
                BitConverter.ToString(BitConverter.GetBytes(anInt)));
            Console.WriteLine(formatter, aShort,
                BitConverter.ToString(BitConverter.GetBytes(aShort)));
            Console.WriteLine(formatter, aChar,
                BitConverter.ToString(BitConverter.GetBytes(aChar)));
            Console.WriteLine(formatter, aBool,
                BitConverter.ToString(BitConverter.GetBytes(aBool)));
            Console.Read();

以上的操作结果
