AE中Shapefile文件添加到SDE数据集 / 四六文摘

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。
