I want to find out all starting indexes of whole word in a given string. Lets say I have a string given below. "an ancient manuscripts, another means to divide sentences into paragraphs was a line break (newline) followed by an initial at the beginning of the next paragraph. An initial is an oversize capital letter, sometimes outdented beyond the margin of text. This style can be seen, for example, in the original Old English manuscript of Beowulf. Outdenting is still used in English typography, though not commonly.[4] Modern English typography usually indicates a new paragraph by indenting

Find word(s) between two values in a string

问题 I have a txt file as a string, and I need to find words between two characters and Ltrim / Rtrim everything else. It may have to be conditional because the two characters may change depending on the string. Example: car= (data between here I want) ; car = (data between here I want) </value> Code: int pos = st.LastIndexOf("car=", StringComparison.OrdinalIgnoreCase); if (pos >= 0) { server = st.Substring(0, pos);.............. } 回答1: This is a simple extension method I use: public static string

MySQL String Last Index Of

I am able to use LOCATE to get the index of a character such as a . in www.google.com . Thus I can use substring to strip out everything before the first . . Is there a way I can look for the last / ? So I can get test.htm out of http://www.example.com/dev/archive/examples/test.htm ? I do not want to say the 6th slash, I want to say the last slash. Can this be done? Use substring_index select substring_index('http://www.example.com/dev/archive/examples/test.htm','/',-1) 来源： https://stackoverflow.com/questions/5796340/mysql-string-last-index-of

strstr() for a string that is NOT null-terminated

由 不想你离开。 提交于 2019-11-29 02:56:49
How do I do the in-place equivalent of strstr() for a counted string (i.e. not null-terminated) in C? If you're afraid of O(m*n) behaviour - basically, you needn't, such cases don't occur naturally - here's a KMP implementation I had lying around which I've modified to take the length of the haystack. Also a wrapper. If you want to do repeated searches, write your own and reuse the borders array. No guarantees for bug-freeness, but it seems to still work. int *kmp_borders(char *needle, size_t nlen){ if (!needle) return NULL; int i, j, *borders = malloc((nlen+1)*sizeof(*borders)); if (!borders)

How to use IndexOf() method of List<object>

由 不想你离开。 提交于 2019-11-29 02:05:25
问题 All the examples I see of using the IndexOf() method in List<T> are of basic string types. What I want to know is how to return the index of a list type that is an object, based on one of the object variables. List<Employee> employeeList = new List<Employee>(); employeeList.Add(new Employee("First","Last",45.00)); I want to find the index where employeeList.LastName == "Something" 回答1: int index = employeeList.FindIndex(employee => employee.LastName.Equals(somename, StringComparison.Ordinal))

MySQL Second (or third) Index Of in String

由 元气小坏坏 提交于 2019-11-29 01:19:57
What would be the simplest way to locate the index of the third space in a string. My goal is to get CCC out of this space separated list: AAAA BBBB CCCC DDDD EEE . where A and B and D are fixed length, and C is variable length, E F G are optional. In Java I would use indexof, with a starting point of 10 and that would get me the third space, but it seems that I cannot do that in MySQL, so I thought maybe I could find a 'third index of' function? You would want to use SUBSTRING_INDEX function like this SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(field, ' ', 3), ' ', -1) FROM table The inner

Getting a collection of index values using a LINQ query

Is there a better way to do this? string[] s = {"zero", "one", "two", "three", "four", "five"}; var x = s .Select((a,i) => new {Value = a, Index = i}) .Where(b => b.Value.StartsWith("t")) .Select(c => c.Index); i.e. I'm looking for a more efficient or more elegant way to get the positions of the items matching the criteria. You could easily add your own extension method: public static IEnumerable<int> IndexesWhere<T>(this IEnumerable<T> source, Func<T, bool> predicate) { int index=0; foreach (T element in source) { if (predicate(element)) { yield return index; } index++; } } Then use it with:
