SharpMap V1.1 For Web教程系列之—

开篇先说本次的开发环境吧。采用Vs2010，.Net Framework 4.0。

为了更好的调试程序，建议在IIS中进行调试及运行，个人非常不喜欢利用VS自己提供的WebServer去调试程序，而且很多在Web.config中的设置也需要在IIS中才能起到效果！

开发环境我就不要介绍了，先来说说SharpMap的组件要求吧。由于SharpMap的架构一直在变化和改进过程中，因此参考网络上别人的事例代码，你会发现都运行不起来，不是接口没了，就是命名空间变了，这点我也希望SharpMap早日稳定下来。

这次使用的SharpMap的版本是V1.1版本，官方意见提供最新稳定版的下载了，官方网址为：http://sharpmap.codeplex.com/

SharpMap 1.1版本的下载地址为：http://sharpmap.codeplex.com/downloads/get/792797，发布时间为2014年12月11日；该版本只是SharpMap的核心库(Core+UI),下载完后，为了Web开发还必须下载一个Web端的库，本人做完因为这一步走了好多弯路，网络上的教程也没有人写上着一点。在官网的DOWNLOADS节点下有个下载界面，需要下载SharpMap.Web这个组件。

OK!所需库完成后，下面进行Asp.Net的网站开发！你也可以不看下面的代码，直接下载整个网站。解决方案下载地址：http://pan.baidu.com/s/1i3vdUcd

打开VS2010,新建一个网站，新建一个WebForm，我这里命名为“Map.aspx”，下面贴代码：
