c# - WPF comparing strings in separate files -

-

I have 2 files with a CSV file and the other is a text file. I need to know that I want to know whether the contained strings contained in the CSV file are present in the text file or not. After doing this check, I want to add those CSV strings which are present in the INMemable collection in the text file which I will use for binding. For example, if CSV Connets "AA", "BB", "CC" and "BB", "EE", "FF", "CC", "BB" in my text "BB", "CC" Should be "bb" I have made a start by reading the CSV file using code below. Can any solution provide PLS? Thanks - Ben 

  public class VM {public VM} {words = load word (file path); } Public IEnumerable & lt; String & gt; Word (get; private set;) string filePath = @ "Z: \ My document \ Words.csv"; Private static IEnumerable & lt; string & gt; load word (string filespath) {list & lt; string & gt; Word = new list & lt; string & gt; (); {foreach (try string line in file (file path)} {string [] rows = line. Try (','); words.AddRange (lines) );}} Hold (Exception e) {System.Windows.MessageBox.Show (e.Message);} Return word;}}    
 
 
 You can do this with LINQ, h By the way:  
  var csv = new [] {"AA", "BB", "CC"}; var text = new [] {"BB", "EE", "FF" , "CC", "BB"}; IEnumerable & lt; string & gt; CollectionToBind = text.Where (t = & gt; csv.Contains (t));    < / Html>

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
