将类转换为字节数组+ C#

Question

如何在C#中将Class转换为字节数组.这是一个托管的,因此以下代码失败

int objsize = System.Runtime.InteropServices.Marshal.SizeOf(objTimeSeries3D);
byte[] arr = new byte[objsize];
IntPtr buff = System.Runtime.InteropServices.Marshal.AllocHGlobal(objsize);
System.Runtime.InteropServices.Marshal.StructureToPtr(objTimeSeries3D, buff, true);
System.Runtime.InteropServices.Marshal.Copy(buff, arr, 0, objsize);
System.Runtime.InteropServices.Marshal.FreeHGlobal(buff);

谢谢

你可以用BinaryFormatter.请注意,您的课程必须[Serializable]为此工作.

private byte[] ToByteArray(object source)
{
    var formatter = new BinaryFormatter();
    using (var stream = new MemoryStream())
    {
        formatter.Serialize(stream, source);                
        return stream.ToArray();
    }
}
