c# - Incrementing a pointer inside a fixed block prohibited, it seems it should work -

-

i error trying increment pointer.

cannot assign ptr because fixed variable cs1656 same error other pointer ptruc

unsafe void organize_data() {     fixed(byte* ptr =  &database[0])     {         fixed(byte* ptruc =  &dtbaseuc[0])         {             strcnt=1;             linestrts[0]=0;             for(int i=0;i<filelen;i++)             {                 if(*ptr > 96 && *ptr < 123)*ptruc=(byte)((int)*ptr-(int)32);                     if(*ptr ==13)                     {                         linestrts[strcnt]=i+1;                         strcnt++;                     }                 ptr++;                 ptruc++;             }         }     }     textbox2.text=strcnt.tostring(); }

variables declared in fixed block read-only , cannot assigned to. must instead copy pointer , increment copy.

fixed (byte* ptr = &database[0]) {     byte* dbptr = ptr;      ptr++;   // cs1656, ptr read-only.     dbptr++; // valid. }
