C# Arcengine编程总结
1、、环境配置：
安装arcengine10.1、arcgis10.1、VS2010
2、、链接SDE工作空间两种方式
public static IWorkspace WorkgroupArcSdeWorkspaceFromString(string connectionString)
{
try
{
Type factoryType = Type.GetTypeFromProgID(
“esriDataSourcesGDB.SdeWorkspaceFactory”);
IWorkspaceFactory2 workspaceFactory2 = (IWorkspaceFactory2)
Activator.CreateInstance(factoryType);
return workspaceFactory2.OpenFromString(connectionString, 0);
}
catch { return null; }
}
public static IWorkspace ConnectToTransactionalVersion(String server, String
instance, String user, String password, String database, String version)
{
IPropertySet propertySet = new PropertySetClass();
propertySet.SetProperty(“SERVER”, server);
propertySet.SetProperty(“INSTANCE”, instance);
propertySet.SetProperty(“DATABASE”, database);
propertySet.SetProperty(“USER”, user);
propertySet.SetProperty(“PASSWORD”, password);
propertySet.SetProperty(“VERSION”, version);
Type factoryType = Type.GetTypeFromProgID(
“esriDataSourcesGDB.SdeWorkspaceFactory”);
IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance
(factoryType);
try
{
return workspaceFactory.Open(propertySet, 0);
}
catch (Exception ex)
{
return null;
}
}
3、坐标系统自定义
public static Dictionary<string, ISpatialReference> SpatialReference()
{
//OpenXmlDocument(坐标系统文件Pro目录,”path”)
string xmlpath = FilePathHelper.OpenXmlDocument(“System//SR_Xian1980_3_Degree_GK_Zone_35”, “path”);
Dictionary<string, ISpatialReference> diction = new Dictionary<string, ISpatialReference>();
ISpatialReferenceFactory pSRF = new SpatialReferenceEnvironmentClass();
ISpatialReference spatial = pSRF.CreateESRISpatialReferenceFromPRJFile(xmlpath);
diction.Add(“XI’AN_1980”, spatial);
spatial = pSRF.CreateGeographicCoordinateSystem((int)esriSRGeoCSType.esriSRGeoCS_WGS1984);
diction.Add(“WGS_1984”, spatial);
return diction;
}
4、坐标系统转换列子，如果将WGS_1984转换XI’AN_1980
public override string getWGS1984ToXian1980(double x, double y, double z)
{
SDEHelper.getEngineLicense();
IPoint ppoint = new PointClass();
ppoint.PutCoords(x, y);
ppoint.Z = z;
IGeometry pgeometry = ppoint as IGeometry;
pgeometry.Project(GISHelper.SpatialReference()[“WGS_1984”]);
pgeometry.Project(GISHelper.SpatialReference()[“XI’AN_1980”]);
string[] fileds={“X”,”Y”,”Z”};//转换后的值
string[] values={ppoint.X+””,ppoint.Y+””,ppoint.Z+””};
return Json.stringToJson(fileds,values);
}
5、如果C#+arcengine发布为webservice时，一定要使用功能时先注册arcengine的license，否则arcengine功能服务使用
6、注册arcengine代码
private static esriLicenseStatus pLicesestatus;//AE licese注册
public static void getEngineLicense()
{
if (m_AoInitialize == null)
{
//ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.EngineOrDesktop);
////初始化License，保证可以访问SDE
// m_AoInitialize = new AoInitializeClass();
//pLicesestatus = (esriLicenseStatus)m_AoInitialize.IsProductCodeAvailable(esriLicenseProductCode.esriLicenseProductCodeEngineGeoDB);
//if (pLicesestatus == esriLicenseStatus.esriLicenseAvailable)
//{
// if (pLicesestatus != esriLicenseStatus.esriLicenseCheckedOut)
// pLicesestatus = (esriLicenseStatus)m_AoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeEngineGeoDB);
//}
//绑定License
//ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.EngineOrDesktop);
ESRI.ArcGIS.RuntimeManager.BindLicense(ESRI.ArcGIS.ProductCode.EngineOrDesktop, ESRI.ArcGIS.LicenseLevel.Standard);
//初始化License，保证可以访问SDE
m_AoInitialize = new AoInitializeClass();
esriLicenseStatus pLicesestatus = (esriLicenseStatus)m_AoInitialize.IsProductCodeAvailable(esriLicenseProductCode.esriLicenseProductCodeEngineGeoDB);
if (pLicesestatus == esriLicenseStatus.esriLicenseAvailable)
{
if (pLicesestatus != esriLicenseStatus.esriLicenseCheckedOut)
pLicesestatus = (esriLicenseStatus)m_AoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeEngineGeoDB);
}
AoInitialize aoi = new AoInitialize();
esriLicenseExtensionCode extensionCodes = esriLicenseExtensionCode.esriLicenseExtensionCodeSpatialAnalyst;
esriLicenseExtensionCode extensionCode = esriLicenseExtensionCode.esriLicenseExtensionCode3DAnalyst;
esriLicenseExtensionCode extensionCode3 = esriLicenseExtensionCode.esriLicenseExtensionCodeAeronautical;
esriLicenseExtensionCode extensionCode4 = esriLicenseExtensionCode.esriLicenseExtensionCodeAGINSPIRE;
esriLicenseExtensionCode extensionCode5 = esriLicenseExtensionCode.esriLicenseExtensionCodeAirports;
esriLicenseExtensionCode extensionCode6 = esriLicenseExtensionCode.esriLicenseExtensionCodeGeoStats;
esriLicenseExtensionCode extensionCode7 = esriLicenseExtensionCode.esriLicenseExtensionCodeRuntimeBasic;
esriLicenseExtensionCode extensionCode8 = esriLicenseExtensionCode.esriLicenseExtensionCodeVector;
esriLicenseExtensionCode extensionCode9 = esriLicenseExtensionCode.esriLicenseExtensionCodeServerStandardEdition;
esriLicenseExtensionCode extensionCode10 = esriLicenseExtensionCode.esriLicenseExtensionCodeServerEnterprise;
esriLicenseExtensionCode extensionCode11 = esriLicenseExtensionCode.esriLicenseExtensionCodeServerAdvancedEdition;
esriLicenseExtensionCode extensionCode12 = esriLicenseExtensionCode.esriLicenseExtensionCodeSchematicsSDK;
esriLicenseExtensionCode extensionCode13 = esriLicenseExtensionCode.esriLicenseExtensionCodeSchematics;
esriLicenseExtensionCode extensionCode14 = esriLicenseExtensionCode.esriLicenseExtensionCodeRuntimeStandard;
esriLicenseExtensionCode extensionCode15 = esriLicenseExtensionCode.esriLicenseExtensionCodeRuntimeAdvanced;
esriLicenseExtensionCode extensionCode16 = esriLicenseExtensionCode.esriLicenseExtensionCodeDataReViewer;
esriLicenseExtensionCode extensionCode17 = esriLicenseExtensionCode.esriLicenseExtensionCodeBusinessStandard;
esriLicenseExtensionCode extensionCode18 = esriLicenseExtensionCode.esriLicenseExtensionCodeBusiness;
esriLicenseExtensionCode extensionCode19 = esriLicenseExtensionCode.esriLicenseExtensionCodeBusinessStandard;
esriLicenseExtensionCode[] obj = { extensionCodes,extensionCode,extensionCode3,extensionCode4,extensionCode5
,extensionCode6,extensionCode7,extensionCode8,extensionCode9
,extensionCode10,extensionCode11,extensionCode12,extensionCode13,extensionCode14
,extensionCode15,extensionCode16,extensionCode17,extensionCode18,extensionCode19, };
esriLicenseProductCode pro = esriLicenseProductCode.esriLicenseProductCodeEngine;
if (aoi.IsProductCodeAvailable(pro) == esriLicenseStatus.esriLicenseAvailable &&
aoi.IsExtensionCodeAvailable(pro, extensionCode) == esriLicenseStatus.esriLicenseAvailable &&
aoi.IsExtensionCodeAvailable(pro, extensionCodes) == esriLicenseStatus.esriLicenseAvailable
)
{
aoi.Initialize(pro);
for (int i = 0; obj.Length > i; i++)
{
aoi.CheckOutExtension(obj[i]);
}
}
}
}
7、获取IfeatureClass的3种方式，通过加载shp路径和打开sde空间表、条件查询sde值
//通过加载shp路径方式获取IFeatureClass
public IFeatureClass getPathIFeatureClass (IGeometry polygon{
IWorkspaceFactory pworkspacefactory = new ShapefileWorkspaceFactoryClass();
IWorkspace pworkspace = pworkspacefactory.OpenFromFile( “C:\\SHP”, 0);
IFeatureWorkspace pfeatureworkspace = pworkspace as IFeatureWorkspace;
IFeatureClass clipfeatureclass = pfeatureworkspace.OpenFeatureClass(“temp.shp”);
IFeatureCursor pfeautrecursor = clipfeatureclass.Search(null, false);
IFeature pfeature = pfeautrecursor.NextFeature();
while (pfeature != null)
{
pfeature.Delete(); //删除元素
pfeature = pfeautrecursor.NextFeature();
}
pfeature = clipfeatureclass.CreateFeature();
pfeature.Shape = polygon;
pfeature.Store();
//关闭资源锁定
IWorkspaceFactoryLockControl ipWsFactoryLock;
ipWsFactoryLock = (IWorkspaceFactoryLockControl)pworkspacefactory;
if (ipWsFactoryLock.SchemaLockingEnabled)
{
ipWsFactoryLock.DisableSchemaLocking();
}
}
//打开sde方式获取IFeatureClass
public static IFeatureClass GetSDEIFeatureClass (IWorkspace work,string featureClassName)
{
try
{
IFeatureWorkspace pFeatureWorkSpace =
work as IFeatureWorkspace;
return pFeatureWorkSpace.OpenFeatureClass(featureClassName);//featureClassName是空间表名称
}
catch { return null; }
}
public IFeatureClass GetFeatureClassByFilter(IWrokSpace space,string filter, string featureClassName)
{
IFeatureWorkspace pFeatureWorkSpace = space as IFeatureWorkspace;
IQueryDef pQueryDef = pFeatureWorkSpace.CreateQueryDef();
pQueryDef.Tables = featureClassName;
pQueryDef.SubFields = “*”;
pQueryDef.WhereClause = filter;//filter查询条件相当于比如: fileter=” 1=1 and id=1″
IFeatureClass pFeatureClass = null;
try
{
IFeatureDataset fDataset = pFeatureWorkSpace.OpenFeatureQuery(“temp”, pQueryDef);
IFeatureClassContainer featureClassContainer = fDataset as IFeatureClassContainer;
pFeatureClass = featureClassContainer.get_ClassByName(“temp”);
}
catch { }
return pFeatureClass;
}
8、创建IGeometry几何对象(可以是IPoint、Polygon、polyline的等)
public IGeometry getGeometry(){
IPointCollection ppointcollection = new PolygonClass();
IPoint ppoint = new PointClass();
ppoint.PutCoords(经度, 纬度);
ppoint.PutCoords(经度, 纬度);
ppoint.PutCoords(经度, 纬度);
object missing = Type.Missing;
ppointcollection.AddPoint(ppoint, ref missing, ref missing);
IPolygon polygon = ppointcollection as IPolygon;//可是是IPoint/IPolyline
//通过坐标集合构建一个闭合面d
IGeometry pgeometry = intersectPolygon as IGeometry;
pgeometry.Project(坐标系统1980); //如果原坐标值是80坐标，那么先将坐标系统设置为1980
pgeometry.Project(坐标系统1984);//第二部才可设置为1984
polygon .Close();
return pgeometry;
}
9、实现增删改查
