How to check null byte that is hexadecimal of 0 in any of encoding formats

0.00/5 (No votes)

See more:

for (int i = 0; i <=data.Length; i++)
           {

               if (data[i] == (byte)0)
                   return true;
           }

Above program works only for ascii encoding but in utf32 encoding its 32 bits so based on encoding format how to check a null byte

Why are you casting the value zero to byte? Without the cast the compiler will coerce it to whataver size necessary based on the item size of your array.

yes correct without typecasting also it works.but my question is i have to check a null byte in any of encoding formats? how to perform that

You should not be testing for null bytes, but null characters, and the character size will depend on the encoding: 8, 16 or 32 bits, or even variable length if it's UTF8.

ok then i need to check whether string contains null character

That's what I said. Or are you still unclear about this issue?
