Question

Arcengine + C# 打开一个固定位置的shapefile的代码。。谢谢

Answer 1

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

IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactory();

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

IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(path, 0);
IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;
IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(fileName);

IFeatureLayer pFeatureLayer = new FeatureLayerClass();
pFeatureLayer.FeatureClass = pFeatureClass;
pFeatureLayer.Name = pFeatureClass.AliasName;
ILayer pLayer = pFeatureLayer as ILayer;

axMapControl.Map.AddLayer(pLayer);
axMapControl.ActiveView.Refresh();
}

希望对你有帮助！

Answer 2

private void btnAddData_Click(object sender, EventArgs e)
{
//axMapControl1.AddShapeFile(string filepath,string filename); 例如：
axMapControl1.AddShapeFile(@"D:\desktop\测试shp","largeData");
}
