You can use Scanner class, which provides a Scanner#nextInt() method to read the next token as int. Now, since your integers are comma(,) separated, you need to set comma(,) as delimiter in your Scanner, which uses whitespace character as default delimiter. You need to use Scanner#useDelimiter(String) method for that. You can use the following code: … Read more
System.IO.File.Move(oldFileName, Path.ChangeExtension(oldFileName, ‘old’)); solved How can I rename .TXT files to .OLD using C#? [closed]

CODE // Regex pattern to match DD.MM.YYYY Format var regexPattern = @”^([0]?[0-9]|[12][0-9]|[3][01])[.]([0]?[1-9]|[1][0-2])[.]([0-9]{4}|[0-9]{2})$”; Regex regexObj = new Regex(regexPattern); // Matched Values matching the regex pattern are returned in IENUMERABLE OF STRING TYPE var dates = File.ReadLines(txtFilePath).Select(lines => lines.Split(‘ ‘).FirstOrDefault(colValue => regexObj.IsMatch(colValue))); 7 solved … Read more
Considering what you are doing, won’t using memcached be a better option? You just store your ips as key=value pairs in memcached, with an expiry of 5 minutes. Thus your data always expires every 5 minutes. Also interaction with memcached is much easier than file-handling. 2 solved How to delete a .txt file after a … Read more
You can reduce the overhead of file I/O by writing to the file in large blocks to reduce the number of individual write operations. #define CHUNK_SIZE 4096 char file_buffer[CHUNK_SIZE + 64] ; // 4Kb buffer, plus enough // for at least one one line int buffer_count = 0 ; int i = 0 ; while( … Read more
