主要完成用C#，通过AE将本地Shapefile文件导入到SDE的指定数据集下面。
首先说下思路：
（1） 通过OpenFileDialog打开本地的Shp文件；
（2）通过获取的Shp文件创建FeatureClass，获取shp的字段 IFields，并判断图层类别;
（3）连接SDE中指定数据集，并创建新的FeatureClass；
（4）将shp文件对应的 FeatureClass里的Feature复制到SDE中新建的FeatureClass中。
接着说明下，开发过程中遇到的一些诡异问题：
（1） 在调用IFeatureDataset的CreateFeatureClass方法时，报错提示：The application is not licensed to create or modify schema for this type of data!
其解决方案 是：修改在form窗体中添加的axLicenseControl的属性，设置为ArcGIS Engine Enterprise...选项；并重新Update下ESRI的License文件。
同时一定要记住，要将除了ArcGIS Engine Enterprise Geo....外的其它选项的勾去掉。
最后为了记录下一天的成果，贴下代码：
（1）调用 OpenFileDialog
| 1 2 3 | openFileDialog1.Filter = ( "ShapeFile 文件(*.shp)|*.shp" ); openFileDialog1.InitialDirectory = "D:\\project\\ThematicDataManager" ; //对话框目录 openFileDialog1.ShowDialog(); |
（2）打开shp文件
| 1 2 3 4 5 6 7 | //打开ShapeFile文件 ShapefileWorkspaceFactory fileWorkspaceFactory = new ShapefileWorkspaceFactoryClass(); IFeatureWorkspace featureWorkspce = fileWorkspaceFactory.OpenFromFile(strWorkspacePath, 0) as IFeatureWorkspace; IFeatureLayer featureLayer = new FeatureLayerClass(); IFeatureClass featureClass = featureWorkspce.OpenFeatureClass(strNewLayer); featureLayer.FeatureClass = featureClass; |
（3）获取shp文件所有字段信息
IFields fields;// = featureClass.Fields;IEnumFieldError pFieldError;IFieldChecker pFieldChecker = new FieldCheckerClass();pFieldChecker.ValidateWorkspace = featureWorkspce as IWorkspace;pFieldChecker.Validate(featureClass.Fields, out pFieldError, out fields);
（4）打开数据集（省略，前面已写过）
（5）创建新要素类
//创建新featureclassIFeatureClass pFCls = ztDataset.CreateFeatureClass(strtemp, fields, null, null, featureClass.FeatureType, featureClass.ShapeFieldName, "");
（6） 在新要素类中添加要素Feature(调用函数)
//追加要素,shp文件追加featureclass中(三个参数：shp文件，shp字段集，sde中FeatureClass文件)private void shp2fc(IFeatureClass featureClass, IFields sourceFeatureClassFields, IFeatureClass pFCls){IQueryFilter queryFilter = new QueryFilterClass();queryFilter.WhereClause = "";IFeatureCursor pFeaCursor = pFCls.Insert(true);IFeatureBuffer pFeaBuffer = pFCls.CreateFeatureBuffer();IField pField = new FieldClass();IFeature pFeature = null;int iIndex = 0;long n = 0;for (int i = 0; i < featureClass.FeatureCount(queryFilter); i++){pFeature = featureClass.GetFeature(i);try{pFeaBuffer = pFCls.CreateFeatureBuffer();//添加字段值for (int j = 0; j < sourceFeatureClassFields.FieldCount; j++){pField = sourceFeatureClassFields.get_Field(j);iIndex = pFeaBuffer.Fields.FindField(pField.Name);if (iIndex != -1){pFeaBuffer.set_Value(iIndex, pFeature.get_Value(j));}}pFeaCursor.InsertFeature(pFeaBuffer);}catch (System.Exception ex){MessageBox.Show("单要素写入异常！" + ex.Message, "提示");return;}finally{n++;if (n % 100 == 0){pFeaCursor.Flush();}}pFeaCursor.Flush();}}
到此，shp文件数据添加到Sde中就完成了。
