ArcEngine加载TIN数据

与加载其它文件略显不同之处在于TIN数据包含若干文件，具体代码如下：

FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();

if (folderBrowserDialog.ShowDialog()==DialogResult.OK)

{

string filePath = folderBrowserDialog.SelectedPath;//选择tin文件夹

string tinPath = Path.GetDirectoryName(filePath);//tin文件夹所在路径

string tinFilePath = Path.GetFileName(filePath);//tin文件夹名称

IWorkspaceFactory pWF = new TinWorkspaceFactoryClass();

IWorkspace pW = pWF.OpenFromFile(tinPath, 0);

ITinWorkspace pTW = pW as ITinWorkspace;

ITin pTin = pTW.OpenTin(tinFilePath);

ITinLayer pTL = new TinLayerClass();

pTL.Dataset = pTin;

axMapControl1.AddLayer(pTL);

}
