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。
