C#实现CAD数据转shape或mdb

jojojojo2002 原文C#实现CAD数据转shape或mdb

　　本文所指的CAD数据为不带空间参考和扩展数据的数据。如果CAD带了空间参考或是扩展属性数据的话，就要采用图形和属性分离的方法转CAD数据，即图形转完后需要挂接属性数据库。这里就不详细说明了. ArcGIS和CAD对空间数据的归纳有所不同，在AutoCad中，点线面可以在同一个图层中，但是在ArcGIS中，点线面被严格的区分为了point、polyline和polygon三种类型的图层，所以直接用ArcCatalog查看CAD数据时会看到五个图层（点线面、注记和Multipatch）话不多说了，进入主题吧。

　　下面的方法实现了点线面图层转成Shape文件：

public bool CadDataToShape(string _cadFilePath)

{

//工作空间

IWorkspaceFactory pWorkspaceFactory;

IFeatureWorkspace pFeatureWorkspace;

IFeatureLayer pFeatureLayer;

IFeatureDataset pFeatureDataset;//图层对应数据集

ESRI.ArcGIS.ConversionTools.FeatureClassToFeatureClass feaTofea = new FeatureClassToFeatureClass();

ESRI.ArcGIS.Geoprocessor.Geoprocessor pGeoPro = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();

try

{

string strFullPath = _cadFilePath;

int index = strFullPath.LastIndexOf("\\");

string filePath = strFullPath.Substring(, index);

string fileName = strFullPath.Substring(index + );

string DataSaveFilePath=@"D:\CADToShape\";

cadGISInfo = new stMdbInfo();

cadGISInfo.mdbFeaturesName = new List<string>();

cadGISInfo.mdbname = fileName;

//打开cad数据集

pWorkspaceFactory = new CadWorkspaceFactoryClass();

pFeatureWorkspace = (IFeatureWorkspace)pWorkspaceFactory.OpenFromFile(filePath, );

if (Directory.Exists(DataSaveFilePath + @"\\" + fileName))

{

    DirectoryInfo dirInfo = new DirectoryInfo(DataSaveFilePath + @"\\" + fileName);

    foreach (FileInfo file in dirInfo.GetFiles())

    {

        file.Delete();

    }

    Directory.Delete(DataSaveFilePath + @"\\" + fileName);

}

Directory.CreateDirectory(DataSaveFilePath + @"\\" + fileName);

cadGISInfo.mdbfilepath = DataSaveFilePath + @"\\" + fileName;

//打开一个要素集

pFeatureDataset = pFeatureWorkspace.OpenFeatureDataset(fileName);

}
