WPF MVVM手敲简单框架 好处是，XAML界面Binding到数据后，只需要更新数据，无需再次手动绑定即可完成界面更新。1.创捷数据类，Model。例如我创建的CarInfo.csnamespace MVVMDemo1 { public class CarInfo { string CarName_; string CarID_; public string CarName { get { return CarName_; } set { CarName_ = value; } } public string CarID { get { return CarID_; } set { CarID_ = value; } } } }2.创建视图数据类，ViewModel。例如我创建的CarInfoViewModel.csusing System.ComponentModel; namespace MVVMDemo1 { public class CarInfoViewModel : INotifyPropertyChanged { CarInfo CarInfo_; public CarInfoViewModel() { CarInfo_ = new CarInfo() {CarName="河南1",CarID="HMB001" }; } public string CarName { get { return CarInfo_.CarName; } set { CarInfo_.CarName = value; RaisePropertyChanged("CarName"); } } public string CarID { get { return CarInfo_.CarID; } set { CarInfo_.CarID = value; RaisePropertyChanged("CarID"); } } /// <summary> /// 实现接口 /// </summary> public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string propertyInfo) { PropertyChangedEventHandler handler = PropertyChanged; if(handler != null) { handler(this,new PropertyChangedEventArgs(propertyInfo)); } } } }3.视图界面声明视图模型Xaml文件中声明视图模型<Window x:Class="MVVMDemo1.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:local="clr-namespace:MVVMDemo1" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> <Window.DataContext> <!--声明创建一个CarViewModel的实例--> <local:CarInfoViewModel/> </Window.DataContext> <Grid> <TextBox HorizontalAlignment="Left" Height="23" Margin="10,10,0,0" TextWrapping="Wrap" Text="{Binding CarName}" VerticalAlignment="Top" Width="120"/> <TextBox HorizontalAlignment="Left" Height="23" Margin="10,38,0,0" TextWrapping="Wrap" Text="{Binding CarID}" VerticalAlignment="Top" Width="120"/> <Button Content="Button" HorizontalAlignment="Left" Margin="195,145,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/> </Grid> </Window>4.关联数据上下文主界面后台关联上下文，实现自动刷新数据using System.Windows; namespace MVVMDemo1 { /// <summary> /// MainWindow.xaml 的交互逻辑 /// </summary> public partial class MainWindow : Window { CarInfoViewModel carInfoViewModel; /// <summary> /// 视图模型 /// </summary> public MainWindow() { InitializeComponent(); //已经在xaml代码中声明了视图模型实例，获取到引用因此我们可以在按钮click事件里使用它 carInfoViewModel = base.DataContext as CarInfoViewModel; } /// <summary> /// 更改数据 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void Button_Click(object sender, RoutedEventArgs e) { //更改数据，界面实时更新 carInfoViewModel.CarID = ""; } } }End -
WPF UI框架 MahApps.Metro 安装您可以MahApps.Metro通过NuGet UI或程序包管理器控制台进行安装。在App.xaml（v1.6.5和更早版本）中添加资源<Application x:Class="WpfApplication.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="MainWindow.xaml"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" /> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" /> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" /> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" /> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> 在v2.0中的App.xaml中添加资源（重大更改）<Application x:Class="WpfApplication.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" StartupUri="MainWindow.xaml"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" /> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" /> <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Themes/Light.Blue.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> 在主窗口中将Window更改为MetroWindow<Controls:MetroWindow x:Class="WpfApplication.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls" Title="MainWindow" Height="600" Width="800"> <Grid> <!-- your content --> </Grid> </Controls:MetroWindow> using MahApps.Metro.Controls; namespace WpfApplication { public partial class MainWindow : MetroWindow { public MainWindow() { InitializeComponent(); } } } 完整的MahApps文档可从https://mahapps.com获得。

WPF GMap.Net开发 GMap.NET是什么？来看看它的官方说明：GMap.NET is great and Powerful, Free, cross platform, open source .NET control. Enable use routing, geocoding, directions and maps from Coogle, Yahoo!, Bing, OpenStreetMap, ArcGIS, Pergo, SigPac, Yendux, Mapy.cz, Maps.lt, iKarte.lv, NearMap, OviMap, CloudMade, WikiMapia, MapQuest in Windows Forms & Presentation, supports caching and runs on windows mobile!GMap.NET是一个强大、免费、跨平台、开源的.NET控件，它在Windows Forms 和WPF环境中能够使用来自Google, Yahoo!, Bing, OpenStreetMap, ArcGIS, Pergo, SigPac等地图，并可以实现寻找路径、地理编码以及地图展示功能，并支持缓存和运行在Mobile环境中。项目主页：https://greatmaps.codeplex.com/Gmap下载下载GMap.Net，编译三个核心项目：GMap.Net.Core：核心DLLGMap.Net.WindowsForms：WinForm中使用的DLLGMap.NET.WindowsPresentation：WPF中使用的DLL如何在WPF中使用GMap.Net1、新建一个Visual C# 的WPF程序。添加对GMap.Net.Core.DLL和GMap.NET.WindowsPresentation.DLL的引用。2、由于WPF的UserControl不能修改继承的基类，所以添加一个新的类，为MapControl.cs，代码如下：using System; using System.Collections.Generic; using System.Linq; using System.Text; using GMap.NET.WindowsPresentation; namespace _7LocationNavigation { class MapControl: GMapControl { } } 只需要继承GMapControl就行了，基本功能都可以由GMapControl提供。3、在我们的MainWindow.xaml中，添加项目的namespace：xmlns:src="clr-namespace:GMapWPFDemo"，在XML代码中添加对MapControl.cs的使用：<Window 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:_7LocationNavigation" xmlns:WindowsPresentation="clr-namespace:GMap.NET.WindowsPresentation;assembly=GMap.NET.WindowsPresentation" x:Class="_7LocationNavigation.MainWindow" mc:Ignorable="d" xmlns:src="clr-namespace:_7LocationNavigation" Title="MainWindow" Height="450" Width="800"> <Grid> <GroupBox Header="GroupBox" HorizontalAlignment="Left" Height="401" Margin="10,10,0,0" VerticalAlignment="Top" Width="773"> <src:MapControl x:Name="mapControl" Zoom="13" MaxZoom="24" MinZoom="1" /> </GroupBox> </Grid> </Window>4、在MainWindow中添加相关的代码如下：引用using GMap.NET; using GMap.NET.MapProviders; using GMap.NET.WindowsPresentation;代码 try { System.Net.IPHostEntry e = System.Net.Dns.GetHostEntry("map.baidu.com"); } catch { mapControl.Manager.Mode = AccessMode.CacheOnly; MessageBox.Show("No internet connection avaible, going to CacheOnly mode.", "GMap.NET Demo", MessageBoxButton.OK, MessageBoxImage.Warning); } mapControl.MapProvider = GMapProviders.GoogleChinaMap; //google china 地图 mapControl.MinZoom = 2; //最小缩放 mapControl.MaxZoom = 17; //最大缩放 mapControl.Zoom = 5; //当前缩放 mapControl.ShowCenter = false; //不显示中心十字点 mapControl.DragButton = MouseButton.Left; //左键拖拽地图 mapControl.Position = new PointLatLng(32.064, 118.704); //地图中心位置：南京 mapControl.MouseLeftButtonDown += new MouseButtonEventHandler(mapControl_MouseLeftButtonDown); } void mapControl_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { Point clickPoint = e.GetPosition(mapControl); PointLatLng point = mapControl.FromLocalToLatLng((int)clickPoint.X, (int)clickPoint.Y); GMapMarker marker = new GMapMarker(point); mapControl.Markers.Add(marker); }参考文章:https://www.cnblogs.com/luxiaoxun/p/3463250.htmlhttps://blog.csdn.net/wshk918/article/details/103076060
