Example

The following example demonstrates how to use UriBasedVectorTileDataProvider to load vector tiles (in PBF format) from a local folder:

C#

ImageLayer layer = new ImageLayer();
UriBasedVectorTileDataProvider dataProvider = new UriBasedVectorTileDataProvider();            
dataProvider.TileUriTemplate = @"D:\PbfFiles\{x}-{y}-{level}.pbf";
layer.DataProvider = dataProvider;
mapControl1.Layers.Add(layer);

VB.NET

Dim layer As ImageLayer = New ImageLayer()
Dim dataProvider As UriBasedVectorTileDataProvider = New UriBasedVectorTileDataProvider()
dataProvider.TileUriTemplate = "D:\PbfFiles\{x}-{y}-{level}.pbf"
layer.DataProvider = dataProvider
mapControl1.Layers.Add(layer)
