Example

In This Topic
    FileSystemDatastore Constructor
    In This Topic
    Opens a folder that contains datasets of type FileSystemConnectionPath.Type. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public FileSystemDatastore( 
       FileSystemConnectionPath connectionPath
    )
    Public Function New( _
       ByVal connectionPath As FileSystemConnectionPath _
    )

    Parameters

    connectionPath
    The folder that contains datasets of a specific FileSystemConnectionPath.Type.
    Exceptions
    ExceptionDescription
    connectionPath is null.
    The directory corresponding to connectionPath does not exist.
    The path to the file-system data store is invalid or the data store cannot be opened.
    A geodatabase-related exception has occurred.
    This object must be created within the lambda or delegate passed to QueuedTask.Run, or on a compatible STA thread.
    Example
    Opening a FeatureClass from a ShapeFile Datastore
    public async Task OpenShapefileFeatureClass()
    {
      await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
      {
        FileSystemConnectionPath fileConnection = new FileSystemConnectionPath(new Uri("path\\to\\folder\\containing\\shapefiles"), FileSystemDatastoreType.Shapefile);
        using (FileSystemDatastore shapefile = new FileSystemDatastore(fileConnection))
        {
          FeatureClass taxLotsFeatureClass = shapefile.OpenDataset<FeatureClass>("TaxLots");
          FeatureClass manHolesFeatureClass = shapefile.OpenDataset<FeatureClass>("ManHoles.shp"); // Can use the .shp extension, but its not needed.
          Table taxDetailsTableWithoutExtension = shapefile.OpenDataset<Table>("TaxDetails");
          Table taxDetailsTable = shapefile.OpenDataset<Table>("TaxDetails.dbf");
        }
      });
    }
    Opening a CAD Datastore
    public async Task OpenCADFeatureClass()
    {
      await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
      {
        FileSystemConnectionPath fileConnection = new FileSystemConnectionPath(new Uri("path\\to\\folder\\containing\\CAD"), FileSystemDatastoreType.Cad);
        using (FileSystemDatastore cadDatastore = new FileSystemDatastore(fileConnection))
        {
          // note - extension is required
          FeatureClass cadDataset = cadDatastore.OpenDataset<FeatureClass>("hatchplayboundaries.dwg");
          // take note of the pattern for referencing a feature class. 
          FeatureClass cadfeatureClass = cadDatastore.OpenDataset<FeatureClass>("hatchplayboundaries.dwg:Polyline");
    
          int numRows = 0;
          using (RowCursor cursor = cadfeatureClass.Search())
          {
            while (cursor.MoveNext())
              numRows++;
          }
        }
      });
    }
    Open raster dataset in a folder
    // Create a FileSystemConnectionPath using the folder path.
    FileSystemConnectionPath connectionPath = new FileSystemConnectionPath(new System.Uri(@"C:\Temp"), FileSystemDatastoreType.Raster);
    // Create a new FileSystemDatastore using the FileSystemConnectionPath.
    FileSystemDatastore dataStore = new FileSystemDatastore(connectionPath);
    // Open the raster dataset.
    RasterDataset fileRasterDataset = dataStore.OpenDataset<RasterDataset>("Sample.tif");
