MapLayerInfo类的代码

根据SKY的要求，特给出MapLayerInfo类的代码，很简单：

public class MapLayerInfo
    {
        private IFeatureLayer _FeatureLayer = null;
        private IMap _Map = null;
        //图层的属性
        private string _FeatLyrName = null;
        private bool _Cached = false;
        private string _DataSourceType = null;
        private string _DisplayField = null;
        private double _MaximumScale = 0;
        private double _MinimunScale = 0;
        private bool _ScaleSymbols = false;
        private bool _Selectable = false;
        private bool _Visible = false;
        private bool _ShowTips = false;

        public MapLayerInfo(IFeatureLayer pFeatLyr, IMap pMap)
        {
            this._FeatureLayer = pFeatLyr;
            this._Map = pMap;

            this._FeatLyrName = pFeatLyr.Name;
            this._DataSourceType = pFeatLyr.DataSourceType;
            this._DisplayField = pFeatLyr.DisplayField;
            this._MaximumScale = pFeatLyr.MaximumScale;
            this._MinimunScale = pFeatLyr.MinimumScale;
            this._Cached = pFeatLyr.Cached;
            this._ScaleSymbols = pFeatLyr.ScaleSymbols;
            this._Selectable = pFeatLyr.Selectable;
            this._Visible = pFeatLyr.Visible;
            this._ShowTips = pFeatLyr.ShowTips;
        }

        //使用[CategoryAttribute("图层基本信息"),DefaultValueAttribute(true)]可以使得该属性在
        //PropertyGrid中显示时出现在“图层基本信息”栏中
        [CategoryAttribute("图层基本信息"), DefaultValueAttribute(true)]
