通过画多边形实现空间查询



如果需要通过画直线查询属性，只需将代码注释段 的注释去掉，再将其下面的那段代码注释起来即可！-Arcengine gis software based on the second development space for the implementation of the functions mapped （ through an inquiry, the selected elements of the property table ） by polygons query if the need for space by line for properties, just put the code comments from the comments and the part of the code comments to you!
