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);

}
