Caliburn.Micro框架之Action Convertions

首先新建一个项目，名称叫Caliburn.Micro.ActionConvertions

然后删掉MainWindow.xaml

然后去app.xaml删掉StartupUri这行代码

其次，安装Caliburn.Micro，Caliburn.Micro.Core，这两个Nuget包，如下图

然后新建一个类Bootstrapper，这个类是引导作用，比如重写了首页的引导，ioc注入等

然后在项目中新建ViewModels，Views，在Views中添加窗口ShellView，在ViewModels中添加类ShellViewModel，如下图

public class Bootstrapper : BootstrapperBase
    {
        private SimpleContainer container;

        public Bootstrapper()
        {
            Initialize();
        }

        protected override void Configure()
        {
            container = new SimpleContainer();

            container.Singleton();

            container.PerRequest();
        }

        protected override void OnStartup(object sender, StartupEventArgs e)
        {
            DisplayRootViewFor();
        }

        protected override object GetInstance(Type service, string key)
        {
            return container.GetInstance(service, key);
        }

        protected override IEnumerable<object> GetAllInstances(Type service)
        {
            return container.GetAllInstances(service);
        }

        protected override void BuildUp(object instance)
        {
            container.BuildUp(instance);
        }
    }

 

再继续新建一个类TaskHelper

TaskHelper类的内容入下

修改ShellViewModel类

public class ShellViewModel : Screen
    {
        private string output;

        public void Clear() => Output = String.Empty;

        public void SimpleSayHello() => Output = "Hello from Caliburn.Micro";

        public void SayHello(string name) => Output = $"Hello {name}";

        public bool CanSayHello(string name) => !String.IsNullOrEmpty(name);

        public Task SayGoodbyeAsync(string name)
        {
            Output = $"Goodbye {name}";

            return TaskHelper.FromResult(true);
        }

        public bool CanSayGoodbye(string name) => !String.IsNullOrEmpty(name);

        public string Output
        {
            get { return output; }
            set { Set(ref output, value); }
        }
    }

然后修改ShellView页面的布局

"Caliburn.Micro.ActionConvertions.Views.ShellView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:i="http://schemas.microsoft.com/xaml/behaviors"
        Title="ShellView" Height="450" Width="800">
    
        
    
    
        
            "24,12">
                
                        "Output:"
                             FontWeight="Bold" />
                        "{Binding Output}" />
                

                "Name" />
                "Name"
                         Margin="0,10,0,0"
                         HorizontalAlignment="Stretch" />

                "Clear"
                        Content="Clear"
                        Style="{StaticResource ActionButtonStyle}" />
                "SimpleSayHello"
                        Content="Simple Say Hello"
                        Style="{StaticResource ActionButtonStyle}" />
                "SimpleSayHello"
                        Content="Simple Say Hello (using Message.Attach)"
                        Style="{StaticResource ActionButtonStyle}" />
                "[Event MouseDoubleClick] = [SimpleSayHello]"
                        Content="Simple Say Hello (Custom Event - Double Tapped)"
                        Style="{StaticResource ActionButtonStyle}" />
                "FullSyntax"
                        Content="Simple Say Hello (Full Behaviour Syntax)"
                        Style="{StaticResource ActionButtonStyle}">
                    
                        "Click">
                            "SimpleSayHello" />
                        
                    
                
                "SayHello"
                        Content="Say Hello (with parameter)"
                        Style="{StaticResource ActionButtonStyle}" />
                "SayHello(Name)"
                        Content="Say Hello (with parameter and Message.Attach)"
                        Style="{StaticResource ActionButtonStyle}" />
                "SayGoodbye"
                        Content="Say Goodbye (async method)"
                        Style="{StaticResource ActionButtonStyle}" />
            
        
    

修改App.xaml的引导程序代码

    
        
            
                
                    "Bootstrapper" />
                
            
        
    

 

然后运行如下图所示
