quotes

问题 I am using CsvHelper I need to wrap all values with quotes. Is that possible? Data = is a List using (StreamWriter textWriter = new StreamWriter(path)) { textWriter.BaseStream.Write(p, 0, p.Length); // var dt = new DataTable(); var csv = new CsvWriter(textWriter); csv.WriteRecords(Data); textWriter.Flush(); textWriter.Close(); } Thanks 回答1: There is a config value called ShouldQuote where you can determine on a field level if it should be quoted. void Main() { var records = new List<Foo> {

问题 In Bash, what are the differences between single quotes ( '' ) and double quotes ( "" )? 回答1: Single quotes won't interpolate anything, but double quotes will. For example: variables, backticks, certain \ escapes, etc. Example: $ echo "$(echo "upg")" upg $ echo '$(echo "upg")' $(echo "upg") The Bash manual has this to say: 3.1.2.2 Single Quotes Enclosing characters in single quotes ( ' ) preserves the literal value of each character within the quotes. A single quote may not occur between

问题 I am trying to extract key-value pairs from a long string in two basic forms, one with and one without quotes, like ... a="First Field" b=SecondField ... using the Java regular expression \b(a|b)\s*(?:=)\s*("[^"]*"|[^ ]*)\b However, running the following test code public static void main(String[] args) { String input = "a=\"First Field\" b=SecondField"; String regex = "\\b(a|b)\\s*(?:=)\\s*(\"[^\"]*\"|[^ ]*)\\b"; Matcher matcher = Pattern.compile(regex).matcher(input); while (matcher.find())

问题 I am trying to learn the best way to write queries. I also understand the importance of being consistent. Until now, I have randomly used single quotes, double quotes, and backticks without any real thought. Example: $query = 'INSERT INTO table (id, col1, col2) VALUES (NULL, val1, val2)'; Also, in the above example, consider that table , col1 , val1 , etc. may be variables. What is the standard for this? What do you do? I've been reading answers to similar questions on here for about 20

问题 Here is the contents of my file (note the nested quotes): <?xml version="1.0" encoding="utf-8"?> <property name="eventData" value='{"key":"value"}'/> in Ruby I have: file = File.read(settings.test_file) @xml = Nokogiri::XML( file) puts "@xml " + @xml.to_s and here is the output: <property name="eventData" value="{"key":"value"}"/> Is there a way to convert it so the output would preserve the quotes exactly? i.e. single on the outside, double on the inside? 回答1: No, it cannot. There is no

问题 I want a regex that will match for example 'panic can''t happen' as panic can''t happen . Double single quotes are just allowed if they're next to each other, 'panic can't' happen' sgould be divided into two strings, panic can and happen . I got \'[^\']*[\'\']?[^\']\' so far but it won't work as expected. Thanks! 回答1: You can try the following: '(?:[^']+|'')+' ' : Matches a literal ' . [^']+ : Matches one or more characters which are not ' . '' : Matches double '' . (?:[^']+|'')+ : Matches

问题 Suppose I have a large string of HTML code. It has both double quotes and single quotes. How can I work with such a string? I want to assign it to a php var but there's a quote clash whether I use double quotes or single quotes. Is there any way to assign this string to a var without having to manually add slashes to all the quotes? It could be something like this: <div class="name">Sally O'Connel</div> Only the string is longer so there will be multiple occurances of single quotes and double

问题 I have written some code to update the player on the story as it progresses. When the player clicks a button they are greeted with some new text and some more options. So far so good, but when I pass a function call in with a parameter attached, I need both single and double quote marks. However, if I use both then this breaks the innerHTML. Code is as follows (can post HTML too if need be): function buttonClicked(buttonid) { switch(buttonid) { case "YesStart": document.getElementById(
