C#結構體和位元組數組的相互轉化

public static class StructCopyer
{
    //相當於序列化與還原序列化，但是不用藉助外部檔案
    //1、struct轉換為Byte[]
    public static Byte[] StructToBytes(Object structure)
    {
        Int32 size = Marshal.SizeOf(structure);
        IntPtr buffer = Marshal.AllocHGlobal(size);

        try
        {
            Marshal.StructureToPtr(structure, buffer, false);
            Byte[] bytes = new Byte[size];
            Marshal.Copy(buffer, bytes, 0, size);

            return bytes;
        }
        finally
        {
            Marshal.FreeHGlobal(buffer);
        }

    }

    //2、Byte[]轉換為struct
    public static Object BytesToStruct(Byte[] bytes, Type strcutType)
    {
        Int32 size = Marshal.SizeOf(strcutType);
        IntPtr buffer = Marshal.AllocHGlobal(size);

        try
        {
            Marshal.Copy(bytes, 0, buffer, size);

            return Marshal.PtrToStructure(buffer, strcutType);
        }
        finally
        {
            Marshal.FreeHGlobal(buffer);
        }
    }

}

用法：

//InterfaceStruct為一結構體
InterfaceStruct pInterface = new InterfaceStruct();

pInterface = (InterfaceStruct)BytesToStruct(bytPipeInfo, pInterface.GetType());
