c# marshaling dynamic-length string
- by mitsky
i have a struct with dynamic length
[StructLayout(LayoutKind.Sequential, Pack = 1)]
struct PktAck
{
public Int32 code;
[MarshalAs(UnmanagedType.LPStr)]
public string text;
}
when i'm converting bytes[] to struct by:
GCHandle handle = GCHandle.Alloc(value, GCHandleType.Pinned);
stru = (T)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(T));
handle.Free();
i have a error, because size of struct less than size of bytes[] and "string text" is pointer to string...
how can i use dynamic strings?
or i can use only this:
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
