本文主要对数据导入等里 常用的不同格式数据创建、转换等 进行代码示例。主要用到IFeatureDataConverter.ConvertFeatureClass方法。

 

代码如下，难度不大，只是个技巧问题：

 

函数：

private void ConvertFeaCls(IWorkspace workspaceSource, IWorkspace workspaceTar, stringsSorceFeaClsName, string sTarFeaClsName, string sFeaDTName)        {            IFeatureClass feaCls = (workspaceSource asIFeatureWorkspace).OpenFeatureClass(sSorceFeaClsName);            String shapeFieldName = feaCls.ShapeFieldName;            int shapeFieldIndex = feaCls.FindField(shapeFieldName);            IField shapeField = feaCls.Fields.get_Field(shapeFieldIndex);            IGeometryDef geometryDef = shapeField.GeometryDef;             //create source workspace name              IDataset sourceWorkspaceDataset = (IDataset)workspaceSource;            IWorkspaceName sourceWorkspaceName = (IWorkspaceName)sourceWorkspaceDataset.FullName;            //create source dataset name              IFeatureClassName sourceFeatureClassName = new FeatureClassNameClass();            IDatasetName sourceDatasetName = (IDatasetName)sourceFeatureClassName;            sourceDatasetName.WorkspaceName = sourceWorkspaceName;            sourceDatasetName.Name = sSorceFeaClsName;             //create target workspace name              IDataset tarWorkspaceDataset = (IDataset)workspaceTar;            IWorkspaceName tarWorkspaceName = (IWorkspaceName)tarWorkspaceDataset.FullName;            //create target dataset name              IFeatureClassName tarFeatureClassName = new FeatureClassNameClass();            IDatasetName tarDatasetName = (IDatasetName)tarFeatureClassName;            tarDatasetName.WorkspaceName = tarWorkspaceName;            tarDatasetName.Name = sTarFeaClsName;             IFeatureDatasetName tarFeatureDatasetName = new FeatureDatasetNameClass();            (tarFeatureDatasetName as IDatasetName).WorkspaceName = tarWorkspaceName;            (tarFeatureDatasetName as IDatasetName).Name = sFeaDTName;             if (string.IsNullOrEmpty(sFeaDTName))            {                tarFeatureDatasetName = null;            }             IFeatureDataConverter featureDataConverter = new FeatureDataConverterClass();            featureDataConverter.ConvertFeatureClass(sourceFeatureClassName, null, tarFeatureDatasetName, tarFeatureClassName, geometryDef, feaCls.Fields, "", 1000, 0);    // Check for errors.        }

 

 

调用：

           

IWorkspaceFactory2 workspaceFactory = new ShapefileWorkspaceFactoryClass() asIWorkspaceFactory2;            IWorkspace workspace = workspaceFactory.OpenFromFile(@"E:\jhl", 0);            IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace;            IFeatureClass featureClass = featureWorkspace.OpenFeatureClass(Functions.g_ROAD);                       IWorkspace workspace2 = workspaceFactory.OpenFromFile(@"E:\", 0);            DeleteShapeFileIFExist(@"E:\", "test6");            ConvertFeaCls(workspace, workspace2, Functions.g_ROAD,  "test6",string.Empty);
