将类转换为字节数组+ C＃ [英] convert a class to byte array + C#

问题描述

如何在C＃中将类转换为字节数组。这是一个托管对象，因此以下代码失败

How can I convert a Class to byte array in C#. This is a managed one so the following code is failing

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

推荐答案

您可以使用 BinaryFormatter 。请注意，您的课程必须为 [可序列化] 。

You can use BinaryFormatter. Note that your class must be [Serializable] for this to work.

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