C String Indexof Returns Unexpected Value Stack Overflow

C String Indexof Returns Unexpected Value Stack Overflow Int i = s.indexof(" ", stringcomparison.ordinal); you can read a small section in the documentation for the string class which has this to say on the subject: string search methods, such as string.startswith and string.indexof, also can perform culture sensitive or ordinal string comparisons. When i try to get the index of the specific string inside the response message (which is also a string), it returns 1 even the specific string is definitely inside the response message. here are the code: int aftertag = hexmessage.indexof(tag); . console.writeline("found!" aftertag); console.readline(); console.writeline("not found!");.

C String Indexof Returns Unexpected Value Stack Overflow I have tested this code in proteus simulator, and actual project too. so, my issue is this one, even if correct password is entered by user,without '#', then also, string.indexof ('#') condition becomes true (returns a non zero value everytime) and thus even valid password is not saved in eeprom. In c#, the indexof () method is a string method. used to find the zero based index of the first occurrence of a specified character or string within the current instance of the string. the method returns 1 if the character or string is not found. this method can be overloaded by passing different parameters to it. 1. string.indexof (char x). The indexof() method accepts a parameter value that is a string to search for. it returns the position of the first occurrence of the string value in the current string. Multiple ways to do it: loop through the friends and just do some if magic use system.linq and directly obtain the friend with friend? f = friends.lastordefault(f => f.name == nombre);. instead of checking for the index, you can check f is null. we haven't been taught how to use linq yet so it'll have to be a loop. aight.

The key is to have the regex match the entire string and extract the substring of interest via a capture group (( )) whose value ($1) can then be used as the replacement string, effectively returning just that. Strstr 返回一个指向找到的字符的指针，因此您可以使用指针算术：（注意：此代码未测试其编译能力，它距离伪代码仅一步之遥。 * 0x10 for example * int index = found source; * index is 8 * * source[8] gets you "i" * 是你想要的。 这是从 此处 提取的示例： char str[] = "fcba73"; char keys[] = "1234567890"; int i; i = strcspn (str,keys); printf ("the first number in str is at position %d.\n",i 1); return 0;. Our implementation builds upon the string.indexof(string, stringcomparison) method from the framework class library, but extends it to also return the length of the match, allowing string manipulation operations to subsequently be performed correctly. When you call a string comparison method such as string pare, string.equals, or string.indexof, you should always call an overload that includes a parameter of type stringcomparison so that you can specify the type of comparison that the method performs.
