在WPF中使用ArcGIS Engine

原文 http://blog.csdn.net/zzahkj/article/details/9102621

1.首先，新建一个WPF项目，添加引用ESRI.ArcGIS.AxControls、ESRI.ArcGIS.System、 ESRI.ArcGIS.Version、ESRI.ArcGIS.Controls、ESRI.ArcGIS.SystemUI，然后拖入 WindowsFormsHost控件到窗体中或者通过在Grid中添加XAML代码实现，如下：

<Grid>
       <WindowsFormsHost Height="54" HorizontalAlignment="Left" Name="windowsFormsHost1" VerticalAlignment="Top" Width="576" />
       <WindowsFormsHost Height="232" HorizontalAlignment="Left" Margin="0,60,0,0" Name="windowsFormsHost2" VerticalAlignment="Top" Width="133" />
       <WindowsFormsHost Height="232" HorizontalAlignment="Left" Margin="139,60,0,0" Name="windowsFormsHost3" VerticalAlignment="Top" Width="437" />
   </Grid>

2.为窗体添加一个WindowsLoad事件，名为Window_Loaded，可通过在Window属性里的事件Load里填写Window_Loaded

或者在代码中直接添加Loaded="Window_Loaded"

3.添加AE控件并建立其与WindowsFormsHost控件的联系，

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using ESRI.ArcGIS.Controls;
using ESRI.ArcGIS.SystemUI;
using System.Windows.Forms;

namespace WpfArcGISEngine
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        AxMapControl mapControl = null;
        AxTOCControl tocControl = null;
        AxToolbarControl toolbarControl = null;
        public MainWindow()
        {
            InitializeComponent();
            CreateEngineControls();
        }
        //建立AE控件与WindowsFormsHost控件的联系
        private void CreateEngineControls()
        {
            mapControl = new AxMapControl();
            windowsFormsHost3.Child = mapControl;
            tocControl = new AxTOCControl();
            windowsFormsHost2.Child = tocControl;
            toolbarControl = new AxToolbarControl();
            windowsFormsHost1.Child = toolbarControl;
        }
        //在Window_Loaded实现TOC与MapControl控件、ToolBar与MapControl之间的绑定
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            tocControl.SetBuddyControl(mapControl);
            toolbarControl.SetBuddyControl(mapControl);
            ToolbarAddItems();
        }
        //ToolBar中添加工具
        private void ToolbarAddItems()
        {
            toolbarControl.AddItem(new ControlsOpenDocCommandClass(), -1, -1, false, -1, esriCommandStyles.esriCommandStyleIconOnly);
            toolbarControl.AddItem(new ControlsSaveAsDocCommandClass(), -1, -1, false, -1, esriCommandStyles.esriCommandStyleIconOnly);
            toolbarControl.AddItem(new ControlsAddDataCommandClass(), -1, -1, false, -1, esriCommandStyles.esriCommandStyleIconOnly);
            toolbarControl.AddItem("esriControls.ControlsMapNavigationToolbar");
            toolbarControl.AddItem("esriControls.ControlsMapIdentifyTool");
        }
    }
}

4.最后运行肯定不会成功，因为没有License的初始化，License初始化的方法是在App.xaml.cs中添加如下的代码实现

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Windows;
using ESRI.ArcGIS.esriSystem;
namespace WpfArcGISEngine
{
    /// <summary>
    /// App.xaml 的交互逻辑
    /// </summary>
    public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);
            ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Engine);
            InitializeEngineLicense();
        }
        private void InitializeEngineLicense()
        {
            AoInitialize aoi = new AoInitializeClass();
            esriLicenseProductCode productCode = esriLicenseProductCode.esriLicenseProductCodeEngine;
            if (aoi.IsProductCodeAvailable(productCode) == esriLicenseStatus.esriLicenseAvailable)
            {
                aoi.Initialize(productCode);
            }
        }
    }
}

现在就可以运行了，运行结果如下：

界面有点丑
