Question

ArcEngine中axMapControl1.AddShapeFile()怎么使用

Answer 1

/// <summary>
/// 打开shapefile文件
/// </summary>
/// <param name="aFileName">Shape文件的全路径</param>
/// <param name="axMapControl"></param>
public void OpenFile_ShapeFile(string aFileName, AxMapControl axMapControl)//打开shapefile文件
{
string fullPath;
string path;//路径
string fileName;//文件名

fullPath = aFileName;
path = System.IO.Path.GetDirectoryName(fullPath);//路径
fileName = System.IO.Path.GetFileName(fullPath);//文件名

//int fileName_Length = fileName.Length;//FileName长
//int lastIndex = fileName.LastIndexOf('\\');//最后一个 \ 的索引
//int fPath_Length = lastIndex;//路径长
//int fPath_IndexStart = 0;//路径在 fileName 开始处 索引
//int fName_Length = fileName_Length - (fPath_Length + 1);//文件名长（包含后缀名）
//int fName_IndexStart = fileName.LastIndexOf('\\') + 1;//文件名在 fileName 开始处 索引
//string fPath = fileName.Substring(fPath_IndexStart, fPath_Length);//路径
//string fName = fileName.Substring(fName_IndexStart, fName_Length);//文件名

axMapControl.AddShapeFile(path, fileName);
axMapControl.ActiveView.Refresh();
}

下面是一些常用的加载数据的函数 可直接 使用，希望对你有帮助！

/// <summary>

/// </summary>
/// <param name="fileNames">打开lyr文件的全路径</param>
/// <param name="axMapControl"></param>
public void OpenFile_lyrFile(string aFileName, AxMapControl axMapControl)//打开*.lyr文件
{
axMapControl.AddLayerFromFile(aFileName);
axMapControl.ActiveView.Refresh();
}

{
string fullPath;
string path;//路径
string fileName;//文件名

fullPath = aFileName;

fileName = System.IO.Path.GetFileName(fullPath);//文件名

//打开CAD数据集
IWorkspaceFactory pWorkspaceFactory = new CadWorkspaceFactoryClass();
IFeatureWorkspace pFeatureWorkspace = (IFeatureWorkspace)pWorkspaceFactory.OpenFromFile(path, 0);
//打开一个要素集
IFeatureDataset pFeatureDataset = pFeatureWorkspace.OpenFeatureDataset(fileName);
//IFeaturClassContainer可以管理IFeatureDataset中的每个要素类

//对CAD文件中的要素进行遍历处理

{

if (pFeatClass.FeatureType == esriFeatureType.esriFTCoverageAnnotation)
{ //如果是注记，则添加注记层
pFeatureLayer = new CadAnnotationLayerClass();
}
else
{ //如果是点、线、面，则添加要素层
pFeatureLayer = new FeatureLayerClass();
}
pFeatureLayer.Name = pFeatClass.AliasName;
pFeatureLayer.FeatureClass = pFeatClass;
axMapControl.Map.AddLayer(pFeatureLayer);
}

axMapControl.ActiveView.Refresh();
}

Answer 2

axMapControl1.AddShapeFile("C:\arcgis\ArcTutor\Spatial","roads.shp");
axMapControl1.AddShapeFile("路径","文件名")
