AE中Shapefile文件添加到SDE数据集

linder_lee 原文 AE中Shapefile文件添加到SDE数据集（c#)

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

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

//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featureclass
IFeatureClass 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。
