Thread: strncmp like function in C#

Hi all!

I try to code a strncmp like function in C# but it does not work.
Thanks for any help or comments :-)!

Code:

public static int strncmp (string s1, string s2, int num)
{
            int i;
            for (i = 0; i < num; i++)
            {
                if (s1[i] == s2[i])
                    return 1;
               

             }

          return 0;

}

What is wrong with string.compare?

Interesting function. It returns 1 (no match) if any character matches. If no characters match, it returns 0 (meaning a match).

You need to review what the return codes from strncmp() mean. 1 doesn't mean "the same." Also, this loop can potentially overrun the string. What if somebody passes a value for num which is larger than either of the two string lengths? Etc.

Thanks for all!
