概述:探索WPF開發(fā)新境界,借助Prism MVVM庫,實現(xiàn)模塊化、可維護的項目。強大的命令系統(tǒng)、松耦合通信、內(nèi)置導(dǎo)航,讓您的開發(fā)更高效、更流暢。
在WPF開發(fā)中,一個優(yōu)秀的MVVM庫是Prism。以下是Prism的優(yōu)點以及基本應(yīng)用示例:
在項目中執(zhí)行以下命令:
Install-Package Prism.Wpf
using Prism.Mvvm;public class MainViewModel : BindableBase{ private string _message; public string Message { get { return _message; } set { SetProperty(ref _message, value); } }}
<Window x:Class="YourNamespace.MainWindow" 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:prism="http://prismlibrary.com/" prism:ViewModelLocator.AutoWireViewModel="True" mc:Ignorable="d" Title="MainWindow" Height="350" Width="525"> <Grid> <TextBlock Text="{Binding Message}" /> </Grid></Window>
在App.xaml.cs中注冊ViewModel:
using Prism.Ioc;using Prism.Unity;using YourNamespace.Views;namespace YourNamespace{ public partial class App : PrismApplication { protected override Window CreateShell() { return Container.Resolve<MainWindow>(); } protected override void RegisterTypes(IContainerRegistry containerRegistry) { containerRegistry.RegisterForNavigation<YourView>(); } }}
<Grid> <TextBlock Text="{Binding Message}" /> <Button Command="{Binding UpdateMessageCommand}" Content="Update Message" /></Grid>
using Prism.Commands;public class MainViewModel : BindableBase{ private string _message; public string Message { get { return _message; } set { SetProperty(ref _message, value); } } public DelegateCommand UpdateMessageCommand { get; } public MainViewModel() { UpdateMessageCommand = new DelegateCommand(UpdateMessage); } private void UpdateMessage() { Message = "Hello, Prism!"; }}
以上是使用Prism的基本示例。Prism提供了更多的功能,如模塊化開發(fā)、事件聚合器、導(dǎo)航框架等,以幫助構(gòu)建結(jié)構(gòu)良好、可維護的WPF應(yīng)用。
