代码如下：
- C# code
using System;using System.Collections.Generic;using System.Configuration;using System.Data;using System.Linq;using System.Windows;//using ESRI.ArcGIS.Controls;using ESRI.ArcGIS.esriSystem;namespace DigitalHomeDesktop{ /// <summary> /// Interaction logic for App.xaml /// </summary> /// 初始化权限 public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Engine); InitializeEngineLincense(); } private void InitializeEngineLincense() { AoInitialize aoi = new AoInitializeClass(); esriLicenseProductCode productcode = esriLicenseProductCode.esriLicenseProductCodeEngine; if (aoi.IsProductCodeAvailable(productcode) ==esriLicenseStatus.esriLicenseAvailable) { aoi.Initialize(productcode); } //throw new NotImplementedException(); }//设置权限方法 }}和ArcGIS的帮助文档里的例子基本上一样，就是不知道为什么还报错。
异常信息如下：
未处理 System.Runtime.InteropServices.COMException
Message=ArcGIS product not specified. You must first bind to an ArcGIS version prior to using any ArcGIS components.
