用C#编写arcgis engine程序，如何查询某个字段里的某项内容

首先查询点坐标的位置要素，然后根据空间查询分析，进行查询县要素上的名称
具体代码如下：

IPoint point = new PointClass();
point.X = 94.82; //你要查询的点坐标位置
point.Y = 32.61; //你要查询的点坐标位置

ISpatialFilter spatialFilter = new SpatialFilterClass();
spatialFilter.Geometry = (point as IPoint) as IGeometry;//设置用于筛选几何对象
spatialFilter.GeometryField = "Shape"; //设置筛选几何字段
spatialFilter.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;//设置空间几何关系

IFeatureLayer featureLayer = this.axMapControl1.Map.get_Layer(0) as IFeatureLayer; //县的图层
IFeatureCursor featureCursor = null;
featureCursor = featureLayer.FeatureClass.Search(spatialFilter, false);
IFeature feature = null;
feature = featureCursor.NextFeature();
while (feature != null)
{
string strName = feature.get_Value(feature.Fields.FindField("NAME")).ToString(); //你要查询的县的名称
feature = featureCursor.NextFeature();
}
System.Runtime.InteropServices.Marshal.ReleaseComObject(featureCursor);
