This is fairly easy, using marshalling.
Top of file
using System.Runtime.InteropServices
Function
byte[] getBytes(CIFSPacket str) {
int size = Marshal.SizeOf(str);
byte[] arr = new byte[size];
IntPtr ptr = Marshal.AllocHGlobal(size);
Marshal.StructureToPtr(str, ptr, true);
Marshal.Copy(ptr, arr, 0, size);
Marshal.FreeHGlobal(ptr);
return arr;
}
And to convert it back:
CIFSPacket fromBytes(byte[] arr) {
CIFSPacket str = new CIFSPacket();
int size = Marshal.SizeOf(str);
IntPtr ptr = Marshal.AllocHGlobal(size);
Marshal.Copy(arr, 0, ptr, size);
str = (CIFSPacket)Marshal.PtrToStructure(ptr, str.GetType());
Marshal.FreeHGlobal(ptr);
return str;
}
In your structure, you will need to put this before a string
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 100)]
public string Buffer;
And make sure SizeConst is as big as your biggest possible string.
And you should probably read this:
