问题 I have a wsdl that imports a schema I am trying to resolve xjc naming multiple nested MyElementName classes with the same name - which doesn't compile I have created this binding file below but it gives the error: parsing a schema... compiling a schema...

问题 I am trying to observe changes of a bool value contained in an ObservableObject which is a value in an enum case. Here is an example of what I am trying to achieve but with the current approach I receive the error Use of unresolved identifier '$type1Value' . import SwiftUI import Combine class ObservableType1: ObservableObject { @Published var isChecked: Bool = false } enum CustomEnum { case option1(ObservableType1) } struct Parent: View { var myCustomEnum: CustomEnum var body: AnyView {

问题 I have the following classes gist with the classes. I want to bind Item.Visible to Items.ItemsVisible - is it possible?, if so - how? Item.cs: using System; using System.ComponentModel; namespace WpfApplication85 { /// <summary> /// Item Object. /// </summary> public class Item : INotifyPropertyChanged { #region INotifyPropertyChanged public event PropertyChangedEventHandler PropertyChanged; //Event to notify when Property changed. /// <summary> /// Notify that Property has Changed. /// <

问题 I'm trying to create a common complex object for my models (action parameters) and reuse it in many places. Here is some sample code: [HttpGet("/api/values")] public ActionResult<string> Get([FromQuery] MyModel model) { var sb = new StringBuilder(); sb.AppendLine(model.Id); sb.AppendLine($"{model.Id}-{model.Generated?.DateStart}-{model.Generated?.DateEnd}"); sb.AppendLine($"{model.Id}-{model.Reference?.DateStart}-{model.Reference?.DateEnd}"); return sb.ToString(); } public class MyModel {

问题 I do not understand the difference between the three syntaxes: where a = f (b) do a <- f (b) do let a = f (b) I do understand somehow though that a <- f(b) is different from the other two, in most cases where I tried all three worked. Also I read somewhere on the net that per block you should try to get along with one let binding only in order to be "idiomatic". But I never seem to manage. How do I decide what to use? 回答1: let foo = bar in ... simply defines foo to be the exact same thing as

问题 The rest of my program binds normally, but this part of the code doesn't work: This is my View: <Window x:Class="TestProject.Views.MainWindowView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:TestProject.Views" xmlns:cal="http://www.caliburnproject.org" mc

问题 From the .NET APIs catalog, I understand that the Microsoft.Win32.Registry class is declared in the .NET Standard + Platform Extensions 2.0 package in an assembly Microsoft.Win32.Registry, Version=4.1.1.0, PublicKeyToken=b03f5f7f11d50a3a . I've created a class library which targets .NET Standard 2.0, and here's a simple class: public class NetStandardClass { public string GetHklmRegValue() { var lmKey = Microsoft.Win32.Registry.LocalMachine; var softwareKey = lmKey.OpenSubKey("Software");

问题 View Binding got released with v3.6. Docs: https://developer.android.com/topic/libraries/view-binding My question is, does anyone know how to use view binding with included layouts?
