SharpMap类型转换- WPF

Question

我想在一个.shp框中显示一个shapefile，我编写了以下代码：

public partial class Details : UserControl { public Details() { InitializeComponent(); SharpMap.Layers.VectorLayer vlay = new SharpMap.Layers.VectorLayer("States"); string path = @"D:\Studies\file.shp"; SharpMap.Map myMap = new SharpMap.Map(new System.Drawing.Size(500, 250)); vlay=new SharpMap.Data.Providers.ShapeFile(path); MapBox.Map.Layers.Add(vlay); MapBox.Map.ZoomToExtents(); } }

它没有运行，它显示：

SharpMap.Data.Providers.ShapeFile可以转换为SharpMap.Layers.VectorLayer

我该怎么办？

指定vlay.DataSource，就像克莱门斯说的：

 SharpMap.Layers.VectorLayer vlay = new SharpMap.Layers.VectorLayer("States");
 string path = @"D:\Studies\file.shp";
 vlay.DataSource = new SharpMap.Data.Providers.ShapeFile(path);
 MapBox.Map.Layers.Add(vlay);
 MapBox.Map.ZoomToExtents();
 MapBox.Refresh();
