使用arcgis engine9.2和.net 开发，检索小区和街道，然后定位. 该如何做，请给些思路或者代码，谢谢

<P>rt</P>

<P>c# 找到了  我再仔细研究研究。</P>
<P>谢谢了</P>

有C#的例子吗？

<P>提示什么错误？光急是没用滴：），下面是帮助里关于查询的例子</P>

<P>ls的说对了，一半是没怎末查资料，多是英文的 看不懂，思考了半天也没有所以然，毕竟是新手。</P>
<P>谢谢</P>

<P>你看看arcobjects开发的顶帖，这个是很基本的内容；</P>
<P>我想你没有查询一些资料或者经过太多思考就提出了这个问题。</P>

哎呀，也没人理我。  论坛的版主干吗去了？！！
