C#中byte类型转换为double类型

// Initialize unmanged memory to hold the array.

int size = Marshal.SizeOf(bytes[0]) * bytes.Length;

IntPtr pnt = Marshal.AllocHGlobal(size);

try

{

// Copy the array to unmanaged memory.

Marshal.Copy(bytes, 0, pnt, bytes.Length);

// Copy the unmanaged array back to another managed array.

double[] managedArray2 = new double[bytes.Length / 8];

Marshal.Copy(pnt, managedArray2, 0, bytes.Length / 8);

return managedArray2;

}

finally

{

// Free the unmanaged memory.

Marshal.FreeHGlobal(pnt);

}
