问题 Consider the following situation: public class A { private ClassInA classInA; public ClassInA getClassInA() { return classInA; } public void setClassInA(ClassInA classInA) { this.classInA = classInA; } } public class B { private ClassInB classInB; public ClassInB getClassInB() { return classInB; } public void setClassInB(ClassInB classInB) { this.classInB = classInB; } } public class ClassInA { private String myString; public String getMyString() { return myString; } public void setMyString

问题 I am setting an IsEnabled property of a control based on whether or not a SelectedIndex >= 0 in a ListBox. I can do this in the code behind, but I wanted to create a value converter for this behavior since it is something I do frequently. I created this Value Converter to handle the task and bound it to the IsEnabled property: [ValueConversion(typeof(Selector), typeof(bool))] public class SelectorItemSelectedToBooleanConverter : IValueConverter { #region IValueConverter Members public object

问题 I'm facing render issues in very complex WPF UI which contains, among other things, a lot of Converters (IValueConverter, IMultiValueConverter). I would like to know if the converters could be involved into this. Does anyone known how WPF Converters worked ? Are they executed in parallel and then synchronized with the UI thread ? or is there some kind of foreach loop that treat every converter ? 回答1: The converters are executed on the UI-thread, you can test this by blocking the thread using

问题 I need int 32 in binary as 00100000 or int 127 in binary 0111 1111 . The variant Integer.toBinaryString returns results only from 1. If I build the for loop this way: for (int i= 32; i <= 127; i + +) { System.out.println (i); System.out.println (Integer.toBinaryString (i)); } And from binary numbers I need the number of leading zeros (count leading zeros (clz) or number of leading zeros (nlz)) I really meant the exact number of 0, such ex: at 00100000 -> 2 and at 0111 1111 - > 1 回答1: Count

问题 Let's say I already have a converter between a custom class Car and String . Is there a way to elegantly make this <f:viewParam name="mycars" value="#{mybean.cars}" converter="carConverter" /> work when mybean.cars is a Set<Car> or List<Car> instead of just a single Car , without having to write a custom converter between lists of cars and lists of strings? In other words, is there some feature of JSF that gets me out of having to parse "[Audi,BMW,VW]" to ["Audi","BMW","VW"] and then convert

问题 I have an F# library that returns an FSharpList to my C# caller. I would now like my C# caller's code to convert this into a List. What is the most efficient way to do this in C#? Thanks. 回答1: Easier than I thouglt... Starting with: List<double> niceList= new List<double>(); From List to FSharpList I did this: FSharpList<double> niceSharpList = ListModule.OfSeq(niceList); and to convert back from FSharpList to List I did: List<double> niceList= niceSharpList.ToList(); 回答2: To make this work

问题 I was tasked with converting a solution from VB to C#. There were 22 projects and hundreds of classes, so I decided to research converters. I finally settled on SharpDevelop, which is an IDE with an included converter. I ran it on each of my projects, and have plenty of errors to fix, but I should be able to go through them and hopefully figure them out. The main issue I am having is with the summary log. I have hundreds of lines for various classes reading: -- line 0 col 0: Case labels with
