在ArcEngine中如何读取tin的数据,需要读所有三角网的点号、坐标?

参考技术A 通过文件夹的方式读入TIN数据即可，系统会自动获取其中的相关信息。当然你也可以通过代码获取 TIN数据中 三角网的点号、坐标。

下面是 C# 读取 TIN数据的代码：
/// <summary>
/// 打开 TIN 文件
/// </summary>
/// <param name="aFolderName">TIN文件夹 名</param>
/// <param name="axMapControl">axMapControl（可已将其换为 Scene
或 Globe 控件）</param>
/// <returns></returns>
public void OpenFile_TINFolder(string aFolderName, AxMapControl axMapControl)//打开TIN文件

string pathToWorkspace = System.IO.Path.GetDirectoryName(aFolderName);
string tinName = System.IO.Path.GetFileName(aFolderName);

IWorkspaceFactory pWorkspaceFactory = new TinWorkspaceFactoryClass();
IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(pathToWorkspace, 0);
ITinWorkspace pTinWorkspace = pWorkspace as ITinWorkspace;
ITinLayer pTinLayer = new TinLayerClass();
if (pTinWorkspace.get_IsTin(tinName))

ITin pTin = pTinWorkspace.OpenTin(tinName);
pTinLayer.Dataset = pTin;
pTinLayer.ClearRenderers();
pTinLayer.Name = tinName;

axMapControl.AddLayer(pTinLayer);
axMapControl.ActiveView.Refresh();
