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 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;

        }

        //使用[CategoryAttribute("图层基本信息"),DefaultValueAttribute(true)]可以使得该属性在
