) As SourceCoordinateSystem

Parameters

Name	Type	Description
prjFileUri	Uri	A Uri object that is the URI to the *.PRJ file.

Returns

Type	Description
SourceCoordinateSystem	A SourceCoordinateSystem class descendant that contains the content of the *.PRJ file.

Remarks

Call the ShapefileDataAdapter.LoadPrjFromStream(Stream) method to load coordinate system metadata from the specified stream.

Example

Form1.cs

data.Add(new MapData() {
    Name = "LoadPrjFile( ) calling loaded coordinate system",
    FileUri = new Uri(baseUri, "../../Shapefiles/Lambert/Belize.shp"),
    CoordinateSystem = ShapefileDataAdapter.LoadPrjFile(new Uri(
        baseUri,
        "../../Shapefiles/Lambert/Projection.prj"))
});

Form1.vb

data.Add(New MapData() With {.Name = "LoadPrjFile( ) calling loaded coordinate system", .FileUri = New Uri(baseUri, "../../Shapefiles/Lambert/Belize.shp"), .CoordinateSystem = ShapefileDataAdapter.LoadPrjFile(New Uri(baseUri, "../../Shapefiles/Lambert/Projection.prj"))})
