arcengine创建dataset COMException

码拜
 

 打开数据库
IFeatureWorkspace pFeatureWorkspace = pWorkspaceFactory.OpenFromFile(@”D:\qqq.mdb”, 0) as IFeatureWorkspace;
设置投影
ISpatialReferenceFactory pSpatialReferenceFac = new SpatialReferenceEnvironmentClass();
            ISpatialReference pSpatialReference = pSpatialReferenceFac.CreateProjectedCoordinateSystem((int)esriSRProjCS4Type.esriSRProjCS_Xian1980_3_Degree_GK_Zone_37);
创建dataset
pFeatureWorkspace.CreateFeatureDataset(“abc”,pSpatialReference);
报错
The XY domain on the spatial reference is not set or invalid.
截图如下

 pSpatialReference 需要设置domian

pSpatialReference.SetDomain(-60000000, 60000000, -60000000, 60000000);

你看看ISpatialReference的SetDomain方法的说明.

ISpatialReferenceFactory pSpatialReferenceEnvironment = new SpatialReferenceEnvironment();
                pComReleaser.ManageLifetime(pSpatialReferenceEnvironment);
                ISpatialReference pSpatialReference = pSpatialReferenceEnvironment.CreateProjectedCoordinateSystem((int)esriSRProjCSType.esriSRProjCS_World_Mercator);
                pComReleaser.ManageLifetime(pSpatialReference);
                pSpatialReferenceEnvironment.CreateGeographicCoordinateSystem((int)esriSRGeoCSType.esriSRGeoCS_WGS1984);
                pSpatialReference.SetDomain(-60000000, 60000000, -60000000, 60000000);
                //创建要素数据集
                IFeatureDataset pFeatureDataset = PGeoDbGeneral.CreateFeatureDataset(pWorkspace, txtFtDataset.Text, pSpatialReference);
                pComReleaser.ManageLifetime(pFeatureDataset);
也可以通过ISpatialReferenceTolerance与ISpatialReferenceResolution默认值达到效果
