arcengine创建dataset COMException

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
40分	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
