[ C# ] Struct To Byte, Byte To Struct

Struct 를 Byte 로, Byte 를 Struct 로 변환하는 소스 입니다.

 

public static byte[] StructToByte(object obj)

{

    int size = Marshal.SizeOf(obj);

    byte[] arr = new byte[size];

    IntPtr ptr = Marshal.AllocHGlobal(size);

 

    Marshal.StructureToPtr(obj, ptr, true);

    Marshal.Copy(ptr, arr, 0, size);

    Marshal.FreeHGlobal(ptr);

    return arr;

}

 

public static T ByteToStruct<T>(byte[] buffer) where T : struct

{

    int size = Marshal.SizeOf(typeof(T));

 

    if (size > buffer.Length)

    {

        throw new Exception();

    }

 

    IntPtr ptr = Marshal.AllocHGlobal(size);

    Marshal.Copy(buffer, 0, ptr, size);

    T obj = (T)Marshal.PtrToStructure(ptr, typeof(T));

    Marshal.FreeHGlobal(ptr);

    return obj;

}
