Windows Server 2008 R2 PowerShell自动部署IIS站点的代码详解

1、功能描述

　　1. 连接软件源服务器下载.NET Framework 4.0、.NET Framework 4.5。

　　2. 检测并判断当前.NET Framework版本是否小于v4.0，如果小于则进行升级。

　　3. 安装IIS组件，安装完成后删除软件及脚本。

　　在升级.NET Framework时，是先从3.5升级(可以通过执行命令"Add-WindowsFeature As-Net-Framework"直接安装3.5)，然后依次升级4.0、4.5。

2、实现

　　源码如下：
