Arcenginee如何自选一个要素类文件打开

要在 ArcEngine 中自选一个要素类文件打开，您可以使用以下代码：

// 创建要素集打开对话框
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.Filter = "Shapefile (*.shp)|*.shp";

// 如果用户选择了文件并点击了“打开”按钮
if (openFileDialog.ShowDialog() == DialogResult.OK)
{
    // 获取选中文件的路径
    string filePath = openFileDialog.FileName;

    // 打开要素类
    IWorkspaceFactory workspaceFactory = new ShapefileWorkspaceFactory();
    IWorkspace workspace = workspaceFactory.OpenFromFile(Path.GetDirectoryName(filePath), 0);
    IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace;
    IFeatureClass featureClass = featureWorkspace.OpenFeatureClass(Path.GetFileNameWithoutExtension(filePath));
}

这段代码会打开一个文件对话框，让用户选择要打开的 Shapefile 文件，然后打开该文件并获取其中的要素类。
