class Program { static void Main(string[] args) { string sourceString = @”<box><3> <table><1> <chair><8>”; Regex ItemRegex = new Regex(@”<(?<item>\w+?)><(?<count>\d+?)>”, RegexOptions.Compiled); foreach (Match ItemMatch in ItemRegex.Matches(sourceString)) { Console.WriteLine(ItemMatch); } Console.ReadLine(); } } Returns 3 matches for me. Your problem must be elsewhere.
The GCC version The GCC one is really quite simple. First of all it is used like this: Q_FOREACH(x, cont) { // do stuff } And that will be expanded to for (QForeachContainer<__typeof__(cont)> _container_(cont); !_container_.brk && _container_.i != _container_.e; __extension__ ({ ++_container_.brk; ++_container_.i; })) for (x = *_container_.i;; __extension__ ({–_container_.brk; break;})) { // do stuff … Read more
Yes, it is possible: Method Syntax: foreach (var person in people.Where(n => n.sex == “male”)) { } Or the rather lengthy Query Syntax: foreach (var person in from person in people where person.sex == “male” select person)
For other Kotlin newbees like me who are coming here just wanting to know how to loop through a collection, I found this in the documentation: val names = listOf(“Anne”, “Peter”, “Jeff”) for (name in names) { println(name) }
If the iteration is being done for its side effect ( as it is in your “print” example ), then a loop is clearer. If the iteration is executed in order to build a composite value, then list comprehensions are usually more readable.
you can do the following… List.Where(x => x.Name.ToString().Equals(“Apple”)).ToList() .ForEach( x => { if(x.Name == “”){}} );
This is a change to the C# language, not the .NET framework. Therefore, it only affects code compiled under C# 5.0, regardless of the .NET framework version on which that code will execute. C# 5.0 Section 8.8.4 of the specification makes it clear that this change has been made. Specifically, page 249 of the C# … Read more
the problem is not with the IEnumerable or the IList it the way you are rendering the collection in your view. @for(var i = 0;i < Model.People.Count;i++) { <tr> <td>@Html.TextBoxFor(m => Model.People[i].Name)</td> <td>@Html.TextBoxFor(m => Model.People[i].Age)</td> </tr> } Observe that with each list item you are appending a continuous index which enables the model binder to … Read more
Well, it’s pretty easy to rig up yourself. Why further pollute the prototypes? Object.keys(obj).forEach(function(key) { var value = obj[key]; }); I think a big reason is that the powers that be want to avoid adding built in properties to Object. Objects are the building blocks of everything in Javascript, but are also the generic key/value … Read more
