我想在SharpMap框中显示一个.shp的shapefile，我写了这段代码：

    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？

分配 vlay。数据来源，就像克莱门斯说：

 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();
