有什么好办法可以将C#的数据类型进行二进制级别的转换?

[lihanbing]

效果如下, 比较麻烦的方法, 有没有更简单直接的方法?

        static void Main(string[] args)
        {
            Byte[] buff = new byte[8];
            MemoryStream ms = new MemoryStream(buff);
            BinaryReader br = new BinaryReader(ms);
            BinaryWriter bw = new BinaryWriter(ms);
            long l;
            double d;
            d = 1235.3424;
            bw.Write(d);
            ms.Seek(0, SeekOrigin.Begin);
            l = br.ReadInt64();
            Console.WriteLine("(double){0} binary convert to long is (long){1}", d,l);
            Console.Read();
        }

输出
(double)1235.3424 binary convert to long is (long)4653147908778690714

double d = 1235.3424;
long c = BitConverter.ToInt64(BitConverter.GetBytes(d), 0);

[lizhibin11]

double d = 1235.3424;
long c = *(long*)&d;

[我姓区不姓区]

long l = BitConverter.ToInt64(buff, 0);

[lizhibin11]

double d = 1235.3424;
long c = Marshal.ReadInt64(d, 0);
