Hi
How can I export selected feature in Layer to Shapefile in VB.NET
This is example how it can export in ArcGIS desktop
https://gis.stackexchange.com/questions/121057/arcmap-vb-net-export-map-to-shp-error
Hi,
You can do it using geoprocessing Feature Class To Shapefile tool.
Geoprocessing API reference is here
I found the solution
is there any expert who can help
need to be able to apply a filter from Layer and determine the file name that will be saved
and know when Geoprocessing has finished processing
This is sample from RawMcGee which I found in the discussion
protected async Task<string> ConvertShp(string layerpath, string outpath)
{
if (!System.IO.Directory.Exists(outpath))
System.IO.Directory.CreateDirectory(outpath);
var valueArray = await QueuedTask.Run(() =>
{
//input layers list should contain the path of each layer name, i.e. if the root node is "Mapping" and the layer name is "gs_points", path is "Mapping\\gs_points".
List<string> inlayers = new List<string>();
inlayers.Add(layerpath);
//outpath is just the folder to save the shapefiles in
return Geoprocessing.MakeValueArray(inlayers, outpath);
});
// to let the GP tool run asynchronously without blocking the main thread
// use the GPThread option of GPExecuteToolFlasgs
//
GPExecuteToolFlags flags = GPExecuteToolFlags.GPThread; // instruct the tool run non-blocking GPThread
IGPResult gpResult = await Geoprocessing.ExecuteToolAsync("FeatureClassToShapefile_conversion", valueArray, null, null, null, flags);
return string.IsNullOrEmpty(gpResult.ReturnValue)
? $@"Error in gp tool: {gpResult.ErrorMessages}"
: $@"Ok: {gpResult.ReturnValue}";
}
Thanks
