BingMap的GeocodeService进行地理位置检索和反向检索--后台实现

一、添加GeocodeService的Web服务引用

        地理编码服务（GeocodeService）是以WCF技术发布的一个Web服务，地图编码服务提供了以一个有效的物理地址在地图上匹配其对应的地图地址（既地理经度和纬度坐标）和以地理经度和纬度坐标进行反向匹配物理地址路径的功能。要使用该服务需添加该服务（http://dev.virtualearth.net/webservices/v1/geocodeservice/GeocodeService.svc）的Web服务引用，如下图

二、通过地址获得经纬度的code：

<span style="font-size:14px;">GeocodeServiceClient geocodeService = new GeocodeServiceClient();
GeocodeRequest geocodeRequest = new GeocodeRequest();
				geocodeRequest.Credentials = new Credentials();
				geocodeRequest.Credentials.ApplicationId = "Arn2694QD8zXQJGN_IgecLbotcSVT1gTyRFfNSdPsIOO - yWjkkZRbwKcNEpCfelq";
				geocodeRequest.Query = sAddress;

				ConfidenceFilter[] filters = new ConfidenceFilter[1];
				filters[0] = new ConfidenceFilter();
				filters[0].MinimumConfidence = Confidence.Low;

				GeocodeOptions geocodeOptions = new GeocodeOptions();
				geocodeOptions.Filters = filters;
				geocodeRequest.Options = geocodeOptions;

				GeocodeResponse geocodeResponse = new GeocodeResponse();
				geocodeResponse = geocodeService.Geocode(geocodeRequest);
				if (geocodeResponse.Results != null)
				{
					int iLength = geocodeResponse.Results.Length;
					if (iLength >= 1)
					{
						string sConfidence = geocodeResponse.Results[0].Confidence.ToString();
						if (sConfidence == "High")
						{
							string sState = geocodeResponse.Results[0].Address.AdminDistrict;
							string sCity = geocodeResponse.Results[0].Address.Locality;
							string sZip = geocodeResponse.Results[0].Address.PostalCode;
							string sLat = geocodeResponse.Results[0].Locations[0].Latitude.ToString();
							string sLon = geocodeResponse.Results[0].Locations[0].Longitude.ToString();
							string sqlExist = "select * from mapping_geodata_boundary where code='NJ0415' and boundary.STContains(geometry::STGeomFromText('POINT(" + sLon + " " + sLat + ")', 0))=1";
							DataTable dtExist = _dataAccess.GetTables(sqlExist);
							if (dtExist.Rows.Count > 0)
							{
								//Update
								string sqlUpdate = "update mapping_parcels set city_state_zip=owner_citystate where city is null and fid=" + id;
								_dataAccess.ExcuateSQL(sqlUpdate);
							}
						}
					}
				}
			}</span>

三、通过经纬度获得地址的Code：

<span style="font-size:14px;">ReverseGeocodeRequest reverseGeocodeRequest = new ReverseGeocodeRequest();
				reverseGeocodeRequest.Credentials = new Credentials();
				reverseGeocodeRequest.Credentials.ApplicationId = "Arn2694QD8zXQJGN_IgecLbotcSVT1gTyRFfNSdPsIOO - yWjkkZRbwKcNEpCfelq";

				Location point = new Location();
				point.Latitude = double.Parse(lat);
				point.Longitude = double.Parse(lon);
				reverseGeocodeRequest.Location = point;

				GeocodeServiceClient geocodeService = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");
				GeocodeResponse geocodeResponse = geocodeService.ReverseGeocode(reverseGeocodeRequest);

				if (geocodeResponse.Results != null)
				{
					int iLength = geocodeResponse.Results.Length;
					if (iLength >= 1)
					{
						string sConfidence = geocodeResponse.Results[0].Confidence.ToString();
						if (sConfidence == "Medium" || sConfidence == "High")
						{
							string sAddress = geocodeResponse.Results[0].DisplayName;
							if (sAddress.Contains("'"))
							{
								sAddress = sAddress.Replace("'", "''");
							}
							string sStreetName = geocodeResponse.Results[0].Address.AddressLine;
							//string sState = geocodeResponse.Results[0].Address.AdminDistrict;
							string sCity = geocodeResponse.Results[0].Address.Locality;
							string sZip = geocodeResponse.Results[0].Address.PostalCode;
							string sLat = geocodeResponse.Results[0].Locations[0].Latitude.ToString();
							string sLon = geocodeResponse.Results[0].Locations[0].Longitude.ToString();
							string sMatchCodes = geocodeResponse.Results[0].MatchCodes[geocodeResponse.Results[0].MatchCodes.Length - 1].ToString();
							string sqlExist = "select * from mapping_geodata_boundary where code='NJ0415' and boundary.STContains(geometry::STGeomFromText('POINT(" + sLon + " " + sLat + ")', 0))=1";
							DataTable dtExist = _dataAccess.GetTables(sqlExist);
							if (dtExist.Rows.Count > 0)
							{
								//Update
								string sqlUpdate = "update mapping_parcels set shape_street_name='" + sStreetName
									+ "',shape_city='" + sCity + "',shape_address='" + sAddress
									+ "',shape_zip='" + sZip + "',shape_matchcode='" + sMatchCodes + "' where fid=" + id;
								_dataAccess.ExcuateSQL(sqlUpdate);
							}
						}
					}
				}</span>
